NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7. Functional description
7.1 Architectural overview
The ARM Cortex-M4 includes three AHB-Lite buses: the system bus, the I-CODE bus,
and the D-code bus. The I-CODE and D-code core buses allow for concurrent code and
data accesses from different slave ports.
The LPC4350/30/20/10 use a multi-layer AHB matrix to connect the ARM Cortex-M4
buses and other bus masters to peripherals in a flexible manner that optimizes
performance by allowing peripherals that are on different slaves ports of the matrix to be
accessed simultaneously by different bus masters.
An ARM Cortex-M0 co-processor is included in the LPC4350/30/20/10, capable of
off-loading the main ARM Cortex-M4 application processor. Most peripheral interrupts are
connected to both processors. The processors communicate with each other via an
interprocessor communication protocol.
7.2 ARM Cortex-M4 processor
The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture
with separate local instruction and data buses as well as a third bus for peripherals, and
includes an internal prefetch unit that supports speculative branching. The ARM
Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A
hardware floating-point processor is integrated in the core. The processor includes an
NVIC with up to 53 interrupts.
7.3 ARM Cortex-M0 co-processor
The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high
performance and very low-power consumption. The ARM Cortex-M0 co-processor uses a
3-stage pipeline von-Neumann architecture and a small but powerful instruction set
providing high-end processing hardware. The co-processor incorporates an NVIC with 32
interrupts.
7.4 Interprocessor communication
The ARM Cortex-M4 and ARM Cortex-M0 interprocessor communication is based on
using shared SRAM as mailbox and one processor raising an interrupt on the other
processor's NVIC, for example after it has delivered a new message in the mailbox. The
receiving processor can reply by raising an interrupt on the sending processor's NVIC to
acknowledge the message.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.5 AHB multilayer matrix
7.6 Nested Vectored Interrupt Controller (NVIC)
The NVIC is an integral part of the Cortex-M4. The tight coupling to the CPU allows for low
interrupt latency and efficient processing of late arriving interrupts.
The ARM Cortex-M0 co-processor has its own NVIC with 32 vectored interrupts. Most
peripheral interrupts are shared between the Cortex-M0 and Cortex-M4 NVICs.

7.6.1 Features
• Controls system exceptions and peripheral interrupts.
• The Cortex-M4 NVIC supports up to 53 vectored interrupts.
• Eight programmable interrupt priority levels with hardware priority level masking.
• Relocatable vector table.
• Non-Maskable Interrupt (NMI).
• Software interrupt generation.
7.6.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags can represent more than one interrupt source.
7.7 System Tick timer (SysTick)
The ARM Cortex-M4 includes a system tick timer (SysTick) that is intended to generate a
dedicated SYSTICK exception at a 10 ms interval.
Remark: The SysTick is not included in the ARM Cortex-M0 core.
7.8 Event router
The event router combines various internal signals, interrupts, and the external interrupt
pins (WAKEUP[3:0]) to create an interrupt in the NVIC, if enabled. In addition, the event
router creates a wake-up signal to the ARM core and the CCU for waking up from Sleep,
Deep-sleep, Power-down, and Deep power-down modes. Individual events can be
configured as edge or level sensitive and can be enabled or disabled in the event router.
The event router can be battery powered.
The following events if enabled in the event router can create a wake-up signal from
sleep, deep-sleep, power-down, and deep power-down modes and/or create an interrupt:
• External pins WAKEUP0/1/2/3 and RESET
• Alarm timer, RTC (32 kHz oscillator running)
The following events if enabled in the event router can create a wake-up signal from sleep
mode only and/or create an interrupt:
• WWDT, BOD interrupts
• C_CAN0/1 and QEI interrupts
• Ethernet, USB0, USB1 signals
• Selected outputs of combined timers (SCTimer/PWM and timer0/1/3)
Remark: Any interrupt can wake up the ARM Cortex-M4 from sleep mode if enabled in
the NVIC.
7.9 Global Input Multiplexer Array (GIMA)
The GIMA routes signals to event-driven peripheral targets like the SCTimer/PWM,
timers, event router, or the ADCs.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7.9.1 Features
• Single selection of a source.
• Signal inversion.
• Can capture a pulse if the input event source is faster than the target clock.
• Synchronization of input event and target clock.
• Single-cycle pulse generation for target.
7.10 On-chip static RAM
The LPC4350/30/20/10 support up to 200 kB local SRAM and an additional 64 kB AHB
SRAM with separate bus master access for higher throughput and individual power
control for low-power operation.
7.11 In-System Programming (ISP)
In-System Programming (ISP) means programming or reprogramming the on-chip SRAM
memory, using the boot loader software and the USART0 serial port. ISP can be
performed when the part resides in the end-user board. ISP loads data into on-chip SRAM
and execute code from on-chip SRAM.
7.12 Boot ROM
The internal ROM memory is used to store the boot code of the LPC4350/30/20/10. After
a reset, the ARM processor will start its code execution from this memory.
The boot ROM memory includes the following features:
• The ROM memory size is 64 kB.
• Supports booting from UART interfaces and external static memory such as NOR
flash, quad SPI flash, and USB0 and USB1.
• Includes API for OTP programming.
• Includes a flexible USB device stack that supports Human Interface Device (HID),
Mass Storage Class (MSC), and Device Firmware Upgrade (DFU) drivers.
Several boot modes are available depending on the values of the OTP bits BOOT_SRC. If
the OTP memory is not programmed or the BOOT_SRC bits are all zero, the boot mode is
determined by the states of the boot pins P2_9, P2_8, P1_2, and P1_1.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7.14 One-Time Programmable (OTP) memory
The OTP provides 64 bit + 256 bit One-Time Programmable (OTP) memory for
general-purpose use.
7.15 General-Purpose I/O (GPIO)
The LPC4350/30/20/10 provide eight GPIO ports with up to 31 GPIO pins each.
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back as well as the current state of the port pins.
All GPIO pins default to inputs with pull-up resistors enabled and input buffer disabled on
reset. The input buffer must be turned on in the system control block SFS register before
the GPIO input can be read.
7.15.1 Features
• Accelerated GPIO functions:
– GPIO registers are located on the AHB so that the fastest possible I/O timing can
be achieved.
– Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
– All GPIO registers are byte and half-word addressable.
– Entire port value can be written in one instruction.
• Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
• Direction control of individual bits.
• Up to eight GPIO pins can be selected from all GPIO pins to create an edge- or
level-sensitive GPIO interrupt request (GPIO interrupts).
• Two GPIO group interrupts can be triggered by any pin or pins in each port (GPIO
group0 and group1 interrupts).
7.16 Configurable digital peripherals
7.16.1 State Configurable Timer (SCTimer/PWM) subsystem
The SCTimer/PWM allows a wide variety of timing, counting, output modulation, and input
capture operations. The inputs and outputs of the SCTimer/PWM are shared with the
capture and match inputs/outputs of the 32-bit general-purpose counter/timers.
The SCTimer/PWM can be configured as two 16-bit counters or a unified 32-bit counter. In
the two-counter case, in addition to the counter value the following operational elements
are independent for each half:
• State variable
• Limit, halt, stop, and start conditions
• Values of Match/Capture registers, plus reload or capture control valuesLPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 4.2 — 18 August 2014 69 of 155
NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
In the two-counter case, the following operational elements are global to the
SCTimer/PWM, but the last three can use match conditions from either counter:
• Clock selection
• Inputs
• Events
• Outputs
• Interrupts
7.16.1.1 Features
• Two 16-bit counters or one 32-bit counter.
• Counters clocked by bus clock or selected input.
• Counters can be configured as up-counters or up-down counters.
• State variable allows sequencing across multiple counter cycles.
• Event combines input or output condition and/or counter match in a specified state.
• Events control outputs and interrupts.
• Selected events can limit, halt, start, or stop a counter.
• Supports:
– up to 8 inputs
– 16 outputs
– 16 match/capture registers
– 16 events
– 32 states
7.16.2 Serial GPIO (SGPIO)
The Serial GPIOs offer standard GPIO functionality enhanced with features to accelerate
serial stream processing.
7.16.2.1 Features
• Each SGPIO input/output slice can be used to perform a serial to parallel or parallel to
serial data conversion.
• 16 SGPIO input/output slices each with a 32-bit FIFO that can shift the input value
from a pin or an output value to a pin with every cycle of a shift clock.
• Each slice is double-buffered.
• Interrupt is generated on a full FIFO, shift clock, or pattern match.
• Slices can be concatenated to increase buffer size.
• Each slice has a 32-bit pattern match filter.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.17 AHB peripherals
7.17.1 General-Purpose DMA (GPDMA)
The DMA controller allows peripheral-to memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receives. The
source and destination areas can each be either a memory region or a peripheral for
master 1, but only memory for master 0.
7.17.1.1 Features
• Eight DMA channels. Each channel can support a unidirectional transfer.
• 16 DMA request lines.
• Single DMA and burst DMA request signals. Each peripheral connected to the DMA
Controller can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the DMA Controller.
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers are supported.
• Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
• Hardware DMA channel priority.
• AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
• Two AHB bus masters for transferring data. These interfaces transfer data when a
DMA request goes active. Master 1 can access memories and peripherals, master 0
can access memories only.
• 32-bit AHB master bus width.
• Incrementing or non-incrementing addressing for source and destination.
• Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data.
• Internal four-word FIFO per channel.
• Supports 8, 16, and 32-bit wide transactions.
• Big-endian and little-endian support. The DMA Controller defaults to little-endian
mode on reset.
• An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
• Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
7.17.2 SPI Flash Interface (SPIFI)
The SPI Flash Interface allows low-cost serial flash memories to be connected to the ARM
Cortex-M4 processor with little performance penalty compared to parallel flash devices
with higher pin count. LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 4.2 — 18 August 2014 71 of 155
NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
After a few commands configure the interface at startup, the entire flash content is
accessible as normal memory using byte, halfword, and word accesses by the processor
and/or DMA channels. Simple sequences of commands handle erasing and
programming.
Many serial flash devices use a half-duplex command-driven SPI protocol for device setup
and initialization and then move to a half-duplex, command-driven 4-bit protocol for
normal operation. Different serial flash vendors and devices accept or require different
commands and command formats. SPIFI provides sufficient flexibility to be compatible
with common flash devices and includes extensions to help insure compatibility with future
devices.
7.17.2.1 Features
• Interfaces to serial flash memory in the main memory map.
• Supports classic and 4-bit bidirectional serial protocols.
• Half-duplex protocol compatible with various vendors and devices.
• Quad SPI Flash Interface (SPIFI) with 1-, 2-, or 4-bit data at rates of up to
52 MB per second.
• Supports DMA access.
7.17.3 SD/MMC card interface
The SD/MMC card interface supports the following modes to control:
• Secure Digital memory (SD version 3.0)
• Secure Digital I/O (SDIO version 2.0)
• Consumer Electronics Advanced Transport Architecture (CE-ATA version 1.1)
• MultiMedia Cards (MMC version 4.4)
7.17.4 External Memory Controller (EMC)
The LPC4350/30/20/10 EMC is a Memory Controller peripheral offering support for
asynchronous static memory devices such as RAM, ROM, and NOR flash. In addition, it
can be used as an interface with off-chip memory-mapped devices and peripherals.
7.17.4.1 Features
• Dynamic memory interface support including single data rate SDRAM.
• Asynchronous static memory device support including RAM, ROM, and NOR flash,
with or without asynchronous page mode.
• Low transaction latency.
• Read and write buffers to reduce latency and to improve performance.
• 8/16/32 data and 24 address lines-wide static memory support.
• 16 bit and 32 bit wide chip select SDRAM memory support.
• Static memory features include:
– Asynchronous page mode read
– Programmable Wait States
– Bus turnaround delayLPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

• Four chip selects for synchronous memory and four chip selects for static memory
devices.
• Power-saving modes dynamically control EMC_CKEOUT and EMC_CLK signals to
SDRAMs.
• Dynamic memory self-refresh mode controlled by software.
• Controller supports 2048 (A0 to A10), 4096 (A0 to A11), and 8192 (A0 to A12) row
address synchronous memory parts. Those are typically 512 MB, 256 MB, and
128 MB parts, with 4, 8, 16, or 32 data bits per device.
• Separate reset domains allow auto-refresh through a chip reset if desired.

7.19 Counter/timers and motor control
7.19.1 General purpose 32-bit timers/external event counters
The LPC4350/30/20/10 include four 32-bit timer/counters. The timer/counter is designed
to count cycles of the system derived clock or an externally-supplied clock. It can
optionally generate interrupts, generate timed DMA requests, or perform other actions at
specified timer values, based on four match registers. Each timer/counter also includes
two capture inputs to trap the timer value when an input signal transitions, optionally
generating an interrupt.
7.19.1.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• Counter or timer operation.
• Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event can also generate an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
• Up to two match registers can be used to generate timed DMA requests.
7.19.2 Motor control PWM
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input causes the PWM to release all
motor drive outputs immediately . At the same time, the motor control PWM is highly
configurable for other generalized timing, counting, capture, and compare applications.
7.19.3 Quadrature Encoder Interface (QEI)
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user code can track the position, direction of rotation,
and velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.
7.19.3.1 Features
• Tracks encoder position.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.19.4 Repetitive Interrupt (RI) timer
The repetitive interrupt timer provides a free-running 32-bit counter which is compared to
a selectable value, generating an interrupt when a match occurs. Any bits of the
timer/compare function can be masked such that they do not contribute to the match
detection. The repetitive interrupt timer can be used to create an interrupt that repeats at
predetermined intervals.
7.19.4.1 Features
• 32-bit counter. Counter can be free-running or be reset by a generated interrupt.
• 32-bit compare value.
• 32-bit compare mask. An interrupt is generated when the counter value equals the
compare value, after masking. This mechanism allows for combinations not possible
with a simple compare.
7.19.5 Windowed WatchDog Timer (WWDT)
The purpose of the watchdog is to reset the controller if software fails to periodically
service it within a programmable time window.
7.19.5.1 Features
• Internally resets chip if not periodically reloaded during the programmable time-out
period.
• Optional windowed operation requires reload to occur between a minimum and
maximum time period, both programmable.
• Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.

on, and optionally when it is off. It uses little power when the CPU does not access its
registers, especially in the reduced power modes. A separate 32 kHz oscillator clocks the
RTC. The oscillator produces a 1 Hz internal time reference and is powered by its own
power supply pin, VBAT.

• Calibration counter allows adjustment to better than 1 sec/day with 1 sec resolution.
• Periodic interrupts can be generated from increments of any field of the time registers.
• Alarm interrupt can be generated for a specific date/time.
7.21.2 Alarm timer
The alarm timer is a 16-bit timer and counts down at 1 kHz from a preset value generating
alarms in intervals of up to 1 min. The counter triggers a status bit when it reaches 0x00
and asserts an interrupt if enabled.
The alarm timer is part of the RTC power domain and can be battery powered.
7.22 System control
7.22.1 Configuration registers (CREG)
The following settings are controlled in the configuration register block:
• BOD trip settings
• Oscillator output
• DMA-to-peripheral muxing
• Ethernet mode
• Memory mapping
• Timer/USART inputs
• Enabling the USB controllers
In addition, the CREG block contains the part identification and part configuration
information.
7.22.2 System Control Unit (SCU)
The system control unit determines the function and electrical mode of the digital pins. By
default function 0 is selected for all pins with pull-up enabled. For pins that support a
digital and analog function, the ADC function select registers in the SCU enable the
analog function.
A separate set of analog I/Os for the ADCs and the DAC as well as most USB pins are
located on separate pads and are not controlled through the SCU.
In addition, the clock delay register for the SDRAM EMC_CLK pins and the registers that
select the pin interrupts are located in the SCU.
7.22.3 Clock Generation Unit (CGU)
The Clock Generator Unit (CGU) generates several base clocks. The base clocks can be
unrelated in frequency and phase and can have different clock sources within the CGU.
One CGU base clock is routed to the CLKOUT pins. The base clock that generates the
CPU clock is referred to as CCLK.
Multiple branch clocks are derived from each base clock. The branch clocks offer flexible
control for power-management purposes. All branch clocks are outputs of one of two
Clock Control Units (CCUs) and can be controlled independently. Branch clocks derived
from the same base clock are synchronous in frequency and phase. LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7.22.4 Internal RC oscillator (IRC)
The IRC is used as the clock source for the WWDT and/or as the clock that drives the
PLLs and the CPU. The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1.5 %
accuracy over the entire voltage and temperature range.
Upon power-up or any chip reset, the LPC4350/30/20/10 use the IRC as the clock source.
The boot loader then configures the PLL1 to provide a 96 MHz clock for the core and the
PLL0USB or PLL0AUDIO as needed if an external boot source is selected.
7.22.5 PLL0USB (for USB0)
PLL0 is a dedicated PLL for the USB0 High-speed controller.
PLL0 accepts an input clock frequency from an external oscillator in the range of 14 kHz
to 25 MHz. The input frequency is multiplied up to a high frequency with a Current
Controlled Oscillator (CCO). The CCO operates in the range of 4.3 MHz to 550 MHz.
7.22.6 PLL0AUDIO (for audio)
The audio PLL PLL0AUDIO is a general-purpose PLL with a small step size. This PLL
accepts an input clock frequency derived from an external oscillator or internal IRC. The
input frequency is multiplied up to a high frequency with a Current Controlled Oscillator
(CCO). A sigma-delta converter modulates the PLL divider ratios to obtain the desired
output frequency. The output frequency can be set as a multiple of the sampling frequency
fs to 32fs, 64fs, 128 fs, 256 fs, 384 fs, 512 fs and the sampling frequency fs can
range from 16 kHz to 192 kHz (16, 22.05, 32, 44.1, 48, 96,192) kHz. Many other
frequencies are possible as well using the integrated fractional divider.
7.22.7 System PLL1
The PLL1 accepts an input clock frequency from an external oscillator in the range of
1 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current
Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO
operates in the range of 156 MHz to 320 MHz. This range is possible through an
additional divider in the loop to keep the CCO within its frequency range while the PLL is
providing the desired output frequency. The output divider can be set to divide by 2, 4, 8,
or 16 to produce the output clock. Since the minimum output divider value is 2, it is
insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed
following a chip reset. After reset, software can enable the PLL. The program must
configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a
clock source. The PLL settling time is 100 s.
7.22.8 Reset Generation Unit (RGU)
The RGU allows generation of independent reset signals for individual blocks and
peripherals on the LPC4350/30/20/10.
7.22.9 Power control
The LPC4350/30/20/10 feature several independent power domains to control power to
the core and the peripherals (see Figure 9). The RTC and its associated peripherals (the
alarm timer, the CREG block, the OTP controller, the back-up registers, and the event
router) are located in the RTC power-domain. The main regulator or a battery supply can
power the RTC. A power selector switch ensures that the RTC block is always powered
on.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
Active mode and sleep mode apply to the state of the core. In a dual-core system, either
core can be in active or sleep mode independently of the other core.
If the core is in Active mode, it is fully operational and can access peripherals and
memories as configured by software. If the core is in Sleep mode, it receives no clocks,
but peripherals and memories remain running.
Either core can enter sleep mode from active mode independently of the other core and
while the other core remains in active mode or is in sleep mode.
Power-down modes apply to the entire system. In the Power-down modes, both cores and
all peripherals except for peripherals in the always-on power domain are shut down.
Memories can remain powered for retaining memory contents as defined by the individual
power-down mode.
Either core in active mode can put the part into one of the three power down modes if the
core is enabled to do so. If both cores are enabled for putting the system into power-down,
then the system enters power-down only once both cores have received a WFI or WFE
instruction.
Wake-up from sleep mode is caused by an interrupt or event in the core’s NVIC. The
interrupt is captured in the NVIC and an event is captured in the Event router. Both cores
can wake up from sleep mode independently of each other.
Wake-up from the Power-down modes, Deep-sleep, Power-down, and Deep power-down,
is caused by an event on the WAKEUP pins or an event from the RTC or alarm timer.
When waking up from Deep power-down mode, the part resets and attempts to boot.
7.23 Serial Wire Debug/JTAG
Debug and trace functions are integrated into the ARM Cortex-M4. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M4 is configured to support up to eight breakpoints and four
watch points.
Remark: Serial Wire Debug is supported for the ARM Cortex-M4 only,
The ARM Cortex-M0 coprocessor supports JTAG debug. A standard ARM
Cortex-compliant debugger can debug the ARM Cortex-M4 and the ARM Cortex-M0
cores separately or both cores simultaneously.
Remark: In order to debug the ARM Cortex-M0, release the M0 reset by software in the
RGU block.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

8. Limiting values
[1] The following applies to the limiting values:
a) This product includes circuitry designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless
otherwise noted.
[2] Including voltage on outputs in 3-state mode.
[3] The peak current is limited to 25 times the corresponding maximum current.
[4] Dependent on package type.
[5] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.

9. Thermal characteristics
The average chip junction temperature, Tj (C), can be calculated using the following
equation:
(1)
• Tamb = ambient temperature (C),
• Rth(j-a) = the package junction-to-ambient thermal resistance (C/W)
• PD = sum of internal and I/O power dissipation
The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of
the I/O pins is often small and many times can be negligible. However it can be significant
in some applications.

12. ADC/DAC electrical characteristics
[1] The ADC is monotonic, there are no missing codes.
[2] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 40.
[3] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See Figure 40.
[4] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 40.
[5] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error, and the straight line which fits the ideal transfer curve. See Figure 40.
[6] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
ADC and the ideal transfer curve. See Figure 40.
[7] Tamb = 25 C.

13.2 Crystal oscillator
The crystal oscillator is controlled by the XTAL_OSC_CTRL register in the CGU (see
LPC43xx user manual).
The crystal oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the PLL.
The oscillator can operate in one of two modes: slave mode and oscillation mode.
• In slave mode, couple the input clock signal with a capacitor of 100 pF (CC in
Figure 42), with an amplitude of at least 200 mV (RMS). The XTAL2 pin in this
configuration can be left unconnected.
• External components and models used in oscillation mode are shown in Figure 43,
and in Table 39 and Table 40. Since the feedback resistance is integrated on chip,
only a crystal and the capacitances CX1 and CX2 need to be connected externally in
case of fundamental mode oscillation L, CL and RS represent the fundamental
frequency). The capacitance CP in Figure 43 represents the parallel package
capacitance and must not be larger than 7 pF. Parameters FC, CL, RS and CP are
supplied by the crystal manufacturer.

13.3 RTC oscillator
In the RTC oscillator circuit, only the crystal (XTAL) and the capacitances CRTCX1 and
CRTCX2 need to be connected externally. Typical capacitance values for CRTCX1 and
CRTCX2 are CRTCX1/2 = 20 (typical) 4 pF.
An external clock can be connected to RTCX1 if RTCX2 is left open. The recommended
amplitude of the clock signal is Vi(RMS) = 100 mV to 200 mV with a coupling capacitance of
5 pF to 10 pF. Vi(RMS) must be lower than 450 mV. See Figure 42 for a similar slave-mode
set-up that uses the crystal oscillator.
13.4 XTAL and RTCX Printed Circuit Board (PCB) layout guidelines
Connect the crystal on the PCB as close as possible to the oscillator input and output pins
of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of third overtone
crystal usage have a common ground plane. Also connect the external components to the
ground plain. To keep the noise coupled in via the PCB as small as possible, make loops
and parasitics as small as possible. Choose smaller values of Cx1 and Cx2 if parasitics
increase in the PCB layout.
Ensure that no high-speed or high-drive signals are near the RTCX1/2 signals.
13.5 Standard I/O pin configuration
Figure 45 shows the possible pin modes for standard I/O pins with analog input function:
• Digital output driver enabled/disabled
• Digital input: Pull-up enabled/disabled
• Digital input: Pull-down enabled/disabled
• Digital input: Repeater mode enabled/disabled
• Digital input: Input buffer enabled/disabled
• Analog input
The default configuration for standard I/O pins is input buffer disabled and pull-up
enabled. The weak MOS devices provide a drive capability equivalent to pull-up and
pull-down resistors.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
On the LPC4350/30/20/10, USBn_VBUS pins are 5 V tolerant only when VDDIO is
applied and at operating voltage level. Therefore, if the USBn_VBUS function is
connected to the USB connector and the device is self-powered, the USBn_VBUS pins
must be protected for situations when VDDIO = 0 V.
If VDDIO is always at operating level while VBUS = 5 V, the USBn_VBUS pin can be
connected directly to the VBUS pin on the USB connector.
For systems where VDDIO can be 0 V and VBUS is directly applied to the USBn_VBUS
pins, precautions must be taken to reduce the voltage to below 3.6 V, which is the
maximum allowable voltage on the USBn_VBUS pins in this case.
One method is to use a voltage divider to connect the USBn_VBUS pins to VBUS on the
USB connector. The voltage divider ratio should be such that the USB_VBUS pin will be
greater than 0.7VDDIO to indicate a logic HIGH while below the 3.6 V allowable maximum
voltage.
For the following operating conditions
VBUSmax = 5.25 V
VDDIO = 3.6 V,
the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V.
For bus-powered devices, a regulator powered by USB can provide 3.3 V to VDDIO
whenever bus power is present and ensure that power to the USBn_VBUS pins is always
present when the 5 V VBUS signal is applied. See Figure 48.
Remark: Applying 5 V to the USBn_VBUS pins for a short time while the regulator ramps
up might compromise the long-term reliability of the part but does not affect its function.

Remark: If the VBUS function of the USB1 interface is not connected, configure the pin
function for GPIO using the function control bits in the SYSCON block.
Remark: In OTG mode, it is important to be able to detect the VBUS level and to charge
and discharge VBUS. This requires adding active devices that disconnect the link when
VDDIO is not present.

includes the functional and electrical specifications and from a system and hardware
viewpoint gives detailed information on how to design-in the device.
Remark: The CLRC632 supports all variants of the MIFARE Mini, MIFARE 1K,
MIFARE 4K and MIFARE Ultralight RF identification protocols. To aid readability
throughout this data sheet, the MIFARE Mini, MIFARE 1K, MIFARE 4K and
MIFARE Ultralight products and protocols have the generic name MIFARE.
2. General description
The CLRC632 is a highly integrated reader IC for contactless communication at
13.56 MHz. The CLRC632 reader IC provides:
• outstanding modulation and demodulation for passive contactless communication
• a wide range of methods and protocols
• a small, fully integrated package
• pin compatibility with the MFRC500, MFRC530, MFRC531 and SLRC400
All protocol layers of the ISO/IEC 14443 A and ISO/IEC 14443 B communication
standards are supported provided:
• additional components, such as the oscillator, power supply, coil etc. are correctly
applied.
• standardized protocols, such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B

9. Functional description
9.1 Digital interface
9.1.1 Overview of supported microprocessor interfaces
The CLRC632 supports direct interfacing to various 8-bit microprocessors. Alternatively,
the CLRC632 can be connected to a PC’s Enhanced Parallel Port (EPP). Table 4 shows
the parallel interface signals supported by the CLRC632.
9.1.2 Automatic microprocessor interface detection
After a Power-On or Hard reset, the CLRC632 resets parallel microprocessor interface
mode and detects the microprocessor interface type.
The CLRC632 identifies the microprocessor interface using the logic levels on the control
pins. This is performed using a combination of fixed pin connections and the dedicated
Initialization routine (see Section 9.7.4 on page 30).

9.1.3.2 Common read and write strobe
Refer to Section 13.4.2 on page 103 for timing specification.
9.1.3.3 Common read and write strobe: EPP with handshake
Refer to Section 13.4.3 on page 104 for timing specification.
Remark: In the EPP standard a chip select signal is not defined. To cover this situation,
the status of the NCS pin can be used to inhibit the nDStrb signal. If this inhibitor is not
used, it is mandatory that pin NCS is connected to pin DVSS.
Remark: After each Power-On or Hard reset, the nWait signal on pin A0 is
high-impedance. nWait is defined as the first negative edge applied to the nAStrb pin after
the reset phase. The CLRC632 does not support Read Address Cycle.
9.1.4 Serial Peripheral Interface
The CLRC632 provides compatibility with the 5-wire Serial Peripheral Interface (SPI)
standard and acts as a slave during the SPI communication. The SPI clock signal SCK
must be generated by the master. Data communication from the master to the slave uses
the MOSI line. The MISO line sends data from the CLRC632 to the master.

Figure 6 shows the microprocessor connection to the CLRC632 using SPI.
Remark: The SPI implementation for CLRC632 conforms to the SPI standard and
ensures that the CLRC632 can only be addressed as a slave.
9.1.4.1 SPI read data
The structure shown in Table 7 must be used to read data using SPI. It is possible to read
up to n-data bytes. The first byte sent defines both, the mode and the address.
The address byte must meet the following criteria:
• the Most Significant Bit (MSB) of the first byte sets the mode. To read data from the
CLRC632 the MSB is set to logic 1
• bits [6:1] define the address
• the Least Significant Bit (LSB) should be set to logic 0.
As shown in Table 8, all the bits of the last byte sent are set to logic 0.

9.2.2.3 Register initialization file (read/write)
The EEPROM memory content from block address 3 to 7 can initialize register sub
addresses 10h to 2Fh when the LoadConfig command is executed (see Section 11.5.1 on
page 95). This command requires the EEPROM starting byte address as a two byte
argument for the initialization procedure.
The byte assignment is shown in Table 16.
The register initialization file is large enough to hold values for two initialization sets and
up to one block (16-byte) of user data. The startup configuration could be adapted to the
I-CODE1 StartUp configuration and stored in register block address 3 and 4, providing
additional flexibility.
Remark: The register initialization file can be read/written by users and these bytes can
be used to store other user data.

9.2.3 Crypto1 keys (write only)
MIFARE security requires specific cryptographic keys to encrypt data stream
communication on the contactless interface. These keys are called Crypto1 keys.
9.2.3.1 Key format
Keys stored in the EEPROM are written in a specific format. Each key byte must be split
into lower four bits k0 to k3 (lower nibble) and the higher four bits k4 to k7 (higher nibble).
Each nibble is stored twice in one byte and one of the two nibbles is bit-wise inverted. This
format is a precondition for successful execution of the LoadKeyE2 (see Section 11.7.1 on
page 97) and LoadKey commands (see Section 11.7.2 on page 97).
Using this format, 12 bytes of EEPROM memory are needed to store a 6-byte key. This is
shown in Figure 7.
Example: The value for the key must be written to the EEPROM.
• If the key was: A0h A1h A2h A3h A4h A5h then
• 5Ah F0h 5Ah E1h 5Ah D2h 5Ah C3h 5Ah B4h 5Ah A5h would be written.
Remark: It is possible to load data for other key formats into the EEPROM key storage
location. However, it is not possible to validate card authentication with data which will
cause the LoadKeyE2 command (see Section 11.7.1 on page 97) to fail.
9.2.3.2 Storage of keys in the EEPROM
The CLRC632 reserves 384 bytes of memory in the EEPROM for the Crypto1 keys. No
memory segmentation is used to mirror the 12-byte structure of key storage. Thus, every
byte of the dedicated memory area can be the start of a key.
Example: If the key loading cycle starts at the last byte address of an EEPROM block, (for
example, key byte 0 is stored at 12Fh), the next bytes are stored in the next EEPROM
block, for example, key byte 1 is stored at 130h, byte 2 at 131h up to byte 11 at 13Ah.
Based on the 384 bytes of memory and a single key needing 12 bytes, then up to 32
different keys can be stored in the EEPROM.
Remark: It is not possible to load a key exceeding the EEPROM byte location 1FFh.

9.3 FIFO buffer
An 8 64 bit FIFO buffer is used in the CLRC632 to act as a parallel-to-parallel converter.
It buffers both the input and output data streams between the microprocessor and the
internal circuitry of the CLRC632. This makes it possible to manage data streams up to 64
bytes long without needing to take timing constraints into account.
9.3.1 Accessing the FIFO buffer
9.3.1.1 Access rules
The FIFO buffer input and output data bus is connected to the FIFOData register. Writing
to this register stores one byte in the FIFO buffer and increments the FIFO buffer write
pointer. Reading from this register shows the FIFO buffer contents stored at the FIFO
buffer read pointer and increments the FIFO buffer read pointer. The distance between the
write and read pointer can be obtained by reading the FIFOLength register.
When the microprocessor starts a command, the CLRC632 can still access the FIFO
buffer while the command is running. Only one FIFO buffer has been implemented which
is used for input and output. Therefore, the microprocessor must ensure that there are no
inadvertent FIFO buffer accesses. Table 18 gives an overview of FIFO buffer access
during command processing.
9.3.2 Controlling the FIFO buffer
In addition to writing to and reading from the FIFO buffer, the FIFO buffer pointers can be
reset using the FlushFIFO bit. This changes the FIFOLength[6:0] value to zero, bit
FIFOOvfl is cleared and the stored bytes are no longer accessible. This enables the FIFO
buffer to be written with another 64 bytes of data.

9.3.3 FIFO buffer status information
The microprocessor can get the following FIFO buffer status data:
• the number of bytes stored in the FIFO buffer: bits FIFOLength[6:0]
• the FIFO buffer full warning: bit HiAlert
• the FIFO buffer empty warning: bit LoAlert
• the FIFO buffer overflow warning: bit FIFOOvfl.
Remark: Setting the FlushFIFO bit clears the FIFOOvfl bit.
The CLRC632 can generate an interrupt signal when:
• bit LoAlertIRq is set to logic 1 and bit LoAlert = logic 1, pin IRQ is activated.
• bit HiAlertIRq is set to logic 1 and bit HiAlert = logic 1, pin IRQ activated.
The HiAlert flag bit is set to logic 1 only when the WaterLevel[5:0] bits or less can be
stored in the FIFO buffer. The trigger is generated by Equation 1:
(1)
The LoAlert flag bit is set to logic 1 when the FIFOLevel register’s WaterLevel[5:0] bits or
less are stored in the FIFO buffer. The trigger is generated by Equation 2:
(2)
9.3.4 FIFO buffer registers and flags
Table 18 shows the related FIFO buffer flags in alphabetic order.
9.4 Interrupt request system
The CLRC632 indicates interrupt events by setting the PrimaryStatus register bit IRq (see
Section 10.5.1.4 “PrimaryStatus register” on page 51) and activating pin IRQ. The signal
on pin IRQ can be used to interrupt the microprocessor using its interrupt handling
capabilities ensuring efficient microprocessor software.

9.4.1 Interrupt sources overview
Table 20 shows the integrated interrupt flags, related source and setting condition. The
interrupt TimerIRq flag bit indicates an interrupt set by the timer unit. Bit TimerIRq is set
when the timer decrements from one down to zero (bit TAutoRestart disabled) or from one
to the TReLoadValue[7:0] with bit TAutoRestart enabled.
Bit TxIRq indicates interrupts from different sources and is set as follows:
• the transmitter automatically sets the bit TxIRq interrupt when it is active and its state
changes from sending data to transmitting the end of frame pattern
• the CRC coprocessor sets the bit TxIRq after all data from the FIFO buffer has been
processed indicated by bit CRCReady = logic 1
• when EEPROM programming is finished, the bit TxIRq is set and is indicated by bit
E2Ready = logic 1
The RxIRq flag bit indicates an interrupt when the end of the received data is detected.
The IdleIRq flag bit is set when a command finishes and the content of the Command
register changes to Idle.
When the FIFO buffer reaches the HIGH-level indicated by the WaterLevel[5:0] value (see
Section 9.3.3 on page 20) and bit HiAlert = logic 1, then the HiAlertIRq flag bit is set to
logic 1.
When the FIFO buffer reaches the LOW-level indicated by the WaterLevel[5:0] value (see
Section 9.3.3 on page 20) and bit LoAlert = logic 1, then LoAlertIRq flag bit is set to
logic 1.
9.4.2 Interrupt request handling
9.4.2.1 Controlling interrupts and getting their status
The CLRC632 informs the microprocessor about the interrupt request source by setting
the relevant bit in the InterruptRq register. The relevance of each interrupt request bit as
source for an interrupt can be masked by the InterruptEn register interrupt enable bits.

NXP Semiconductors CLRC632
Standard multi-protocol reader solution
If any interrupt request flag is set to logic 1 (showing that an interrupt request is pending)
and the corresponding interrupt enable flag is set, the PrimaryStatus register IRq flag bit is
set to logic 1. Different interrupt sources can activate simultaneously because all interrupt
request bits are OR’ed, coupled to the IRq flag and then forwarded to pin IRQ.
9.4.2.2 Accessing the interrupt registers
The interrupt request bits are automatically set by the CLRC632’s internal state machines.
In addition, the microprocessor can also set or clear the interrupt request bits as required.
A special implementation of the InterruptRq and InterruptEn registers enables changing
an individual bit status without influencing any other bits. If an interrupt register is set to
logic 1, bit SetIxx and the specific bit must both be set to logic 1 at the same time. Vice
versa, if a specific interrupt flag is cleared, zero must be written to the SetIxx and the
interrupt register address must be set to logic 1 at the same time.
If a content bit is not changed during the setting or clearing phase, zero must be written to
the specific bit location.
Example: Writing 3Fh to the InterruptRq register clears all bits. SetIRq is set to logic 0
while all other bits are set to logic 1. Writing 81h to the InterruptRq register sets LoAlertIRq
to logic 1 and leaves all other bits unchanged.
9.4.3 Configuration of pin IRQ
The logic level of the IRq flag bit is visible on pin IRQ. The signal on pin IRQ can also be
controlled using the following IRQPinConfig register bits.
• bit IRQInv: the signal on pin IRQ is equal to the logic level of bit IRq when this bit is set
to logic 0. When set to logic 1, the signal on pin IRQ is inverted with respect to bit IRq.
• bit IRQPushPull: when set to logic 1, pin IRQ has CMOS output characteristics. When
it is set to logic 0, it is an open-drain output which requires an external resistor to
achieve a HIGH-level at pin IRQ.
Remark: During the reset phase (see Section 9.7.2 on page 29) bit IRQInv is set to
logic 1 and bit IRQPushPull is set to logic 0. This results in a high-impedance on pin IRQ.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

9.5 Timer unit
The timer derives its clock from the 13.56 MHz on-board chip clock. The microprocessor
can use this timer to manage timing-relevant tasks.
The timer unit may be used in one of the following configurations:
• Timeout counter
• WatchDog counter
• Stopwatch
• Programmable one shot
• Periodical trigger
The timer unit can be used to measure the time interval between two events or to indicate
that a specific timed event occurred. The timer is triggered by events but does not
influence any event (e.g. a time-out during data receiving does not automatically influence
the receiving process). Several timer related flags can be set and these flags can be used
to generate an interrupt.

9.5.1.1 Timer unit block diagram
Figure 8 shows the block diagram of the timer module.
The timer unit is designed, so that events when combined with enabling flags start or stop
the counter. For example, setting bit TStartTxBegin = logic 1 enables control of received
data with the timer unit. In addition, the first received bit is indicated by the TxBegin event.
This combination starts the counter at the defined TReloadValue[7:0].
The timer stops automatically when the counter value is equal to zero or if a defined stop
event happens.
9.5.1.2 Controlling the timer unit
The main part of the timer unit is a down-counter. As long as the down-counter value is
not zero, it decrements its value with each timer clock cycle.
If the TAutoRestart flag is enabled, the timer does not decrement down to zero. On
reaching value 1, the timer reloads the next clock function with the TReloadValue[7:0].

The timer is started immediately by loading a value from the TimerReload register into the
counter module.
This is activated by one of the following events:
• transmission of the first bit to the card (TxBegin event) with bit TStartTxBegin = logic 1
• transmission of the last bit to the card (TxEnd event) with bit TStartTxEnd = logic 1
• bit TStartNow is set to logic 1 by the microprocessor
Remark: Every start event reloads the timer from the TimerReload register. Thus, the
timer unit is re-triggered.
The timer can be configured to stop on one of the following events:
• receipt of the first valid bit from the card (RxBegin event) with bit
TStopRxBegin = logic 1
• receipt of the last bit from the card (RxEnd event) with bit TStopRxEnd = logic 1
• the counter module has decremented down to zero and bit TAutoRestart = logic 0
• bit TStopNow is set to logic 1 by the microprocessor.
Loading a new value, e.g. zero, into the TimerReload register or changing the timer unit
while it is counting will not immediately influence the counter. In both cases, this is
because this register only affects the counter content after a start event.
If the counter is stopped when bit TStopNow is set, no TimerIRq is flagged.
9.5.1.3 Timer unit clock and period
The timer unit clock is derived from the 13.56 MHz on-board chip clock using the
programmable divider. Clock selection is made using the TimerClock register
TPreScaler[4:0] bits based on Equation 3:
(3)
The values for the TPreScaler[4:0] bits are between 0 and 21 which results in a minimum
periodic time (TTimerClock) of between 74 ns and 150 ms.
The time period elapsed since the last start event is calculated using Equation 4:
(4)
This results in a minimum time period (tTimer) of between 74 ns and 40 s.
9.5.1.4 Timer unit status
The SecondaryStatus register’s TRunning bit shows the timer’s status. Configured start
events start the timer at the TReloadValue[7:0] and changes the status flag TRunning to
logic 1. Conversely, configured stop events stop the timer and sets the TRunning status
flag to logic 0. As long as status flag TRunning is set to logic 1, the TimerValue register
changes on the next timer unit clock cycle.
The TimerValue[7:0] bits can be read directly from the TimerValue register.

9.5.1.5 TimeSlotPeriod
When sending I-CODE1 Quit frames, it is necessary to generate the exact chronological
relationship to the start of the command frame.
If at the end of command execution TimeSlotPeriod > 0, the TimeSlotPeriod starts. If the
FIFO buffer contains data when the end of TimeSlotPeriod is reached, the data is sent. If
the FIFO buffer is empty nothing happens. As long as the TimeSlotPeriod is > 0, the
TimeSlotPeriod counter automatically starts on reaching the end.
This forms the exact time relationship between the start and finish of the command frame
used to generate and send I-CODE1 Quit frames.
When the TimeSlotPeriod > 0, the next Frame starts with exactly the same interval
TimeSlotPeriod/CoderRate delayed after each previous send frame. CoderRate defines
the clock frequency of the encoder. If TimeSlotPeriod[7:0] = 0, the send function is not
automatically triggered.
The content of the TimeSlotPeriod register can be changed while it is running but the
change is only effective after the next TimeSlotPeriod restart.
Example:
• CoderRate = 0 0.5 (~52.97 kHz)
• The interval should be 8.458 ms for I-CODE1 standard mode
Remark: The TimeSlotPeriodMSB bit is contained in the MFOUTSelect register.
Remark: Set bit TxCRCEn to logic 0 before the Quit frame is sent. If TxCRCEn is not set
to logic 0, the Quit frame is sent with a calculated CRC value. Use the CRC8 algorithm to
calculate the Quit value.

9.5.2 Using the timer unit functions
9.5.2.1 Time-out and WatchDog counters
After starting the timer using TReloadValue[7:0], the timer unit decrements the TimerValue
register beginning with a given start event. If a given stop event occurs, such as a bit
being received from the card, the timer unit stops without generating an interrupt.
If a stop event does not occur, such as the card not answering within the expected time,
the timer unit decrements down to zero and generates a timer interrupt request. This
signals to the microprocessor the expected event has not occurred within the given time
(tTimer).
9.5.2.2 Stopwatch
The time (tTimer) between a start and stop event is measured by the microprocessor using
the timer unit. Setting the TReloadValue register triggers the timer which in turn, starts to
decrement. If the defined stop event occurs, the timer stops. The time between start and
stop is calculated by the microprocessor using Equation 5, when the timer does not
decrement down to zero.
(5)
9.5.2.3 Programmable one shot timer and periodic trigger
Programmable one shot timer: The microprocessor starts the timer unit and waits for
the timer interrupt. The interrupt occurs after the time specified by tTimer.
Periodic trigger: If the microprocessor sets the TAutoRestart bit, it generates an interrupt
request after every tTimer cycle.

9.6 Power reduction modes
9.6.1 Hard power-down
Hard power-down is enabled when pin RSTPD is HIGH. This turns off all internal current
sinks including the oscillator. All digital input buffers are separated from the input pads and
defined internally (except pin RSTPD itself). The output pins are frozen at a given value.
The status of all pins during a hard power-down is shown in Table 25.
9.6.2 Soft power-down mode
Soft power-down mode is entered immediately using the Control register bit PowerDown.
All internal current sinks, including the oscillator buffer, are switched off. The digital input
buffers are not separated from the input pads and keep their functionality. In addition, the
digital output pins do not change their state.
After resetting the Control register bit PowerDown, the bit indicating Soft power-down
mode is only cleared after 512 clock cycles. Resetting it does not immediately clear it. The
PowerDown bit is automatically cleared when the Soft power-down mode is exited.
Remark: When the internal oscillator is used, time (tosc) is required for the oscillator to
become stable. This is because the internal oscillator is supplied by VDDA and any clock
cycles will not be detected by the internal logic until VDDA is stable.

9.6.3 Standby mode
The Standby mode is immediately entered when the Control register StandBy bit is set. All
internal current sinks, including the internal digital clock buffer are switched off. However,
the oscillator buffer is not switched off.
The digital input buffers are not separated by the input pads, keeping their functionality
and the digital output pins do not change their state. In addition, the oscillator does not
need time to wake-up.
After resetting the Control register StandBy bit, it takes four clock cycles on pin OSCIN for
Standby mode to exit. Resetting bit StandBy does not immediately clear it. It is
automatically cleared when the Standby mode is exited.
9.6.4 Automatic receiver power-down
It is a power saving feature to switch off the receiver circuit when it is not needed. Setting
bit RxAutoPD = logic 1, automatically powers down the receiver when it is not in use.
Setting bit RxAutoPD = logic 0, keeps the receiver continuously powered up.
9.7 StartUp phase
The events executed during the StartUp phase are shown in Figure 10.
9.7.1 Hard power-down phase
The hard power-down phase is active during the following cases:
• a Power-On Reset (POR) caused by power-up on pins DVDD or AVDD activated
when VDDD or VDDA is below the digital reset threshold.
• a HIGH-level on pin RSTPD which is active while pin RSTPD is HIGH. The HIGH level
period on pin RSTPD must be at least 100 s (tPD 100 s). Shorter phases will not
necessarily result in the reset phase (treset). The rising or falling edge slew rate on pin
RSTPD is not critical because pin RSTPD is a Schmitt trigger input.
9.7.2 Reset phase
The reset phase automatically follows the Hard power-down. Once the oscillator is
running stably, the reset phase takes 512 clock cycles. During the reset phase, some
register bits are preset by hardware. The respective reset values are given in the
description of each register (see Section 10.5 on page 50).
Remark: When the internal oscillator is used, time (tosc) is required for the oscillator to
become stable. This is because the internal oscillator is supplied by VDDA and any clock
cycles will not be detected by the internal logic until VDDA is stable.

9.7.3 Initialization phase
The initialization phase automatically follows the reset phase and takes 128 clock cycles.
During the initializing phase the content of the EEPROM blocks 1 and 2 is copied into the
register subaddresses 10h to 2Fh (see Section 9.2.2 on page 13).
Remark: During the production test, the CLRC632 is initialized with default configuration
values. This reduces the microprocessor’s configuration time to a minimum.
9.7.4 Initializing the parallel interface type
A different initialization sequence is used for each microprocessor. This enables detection
of the correct microprocessor interface type and synchronization of the microprocessor’s
and the CLRC632’s start-up. See Section 9.1.3 on page 8 for detailed information on the
different connections for each microprocessor interface type.
During StartUp phase, the command value is set to 3Fh once the oscillator attains clock
frequency stability at an amplitude of > 90 % of the nominal 13.56 MHz clock frequency. At
the end of the initialization phase, the CLRC632 automatically switches to idle and the
command value changes to 00h.
To ensure correct detection of the microprocessor interface, the following sequence is
executed:
• the Command register is read until the 6-bit register value is 00h. On reading the 00h
value, the internal initialization phase is complete and the CLRC632 is ready to be
controlled
• write 80h to the Page register to initialize the microprocessor interface
• read the Command register. If it returns a value of 00h, the microprocessor interface
was successfully initialized
• write 00h to the Page registers to activate linear addressing mode.
9.8 Oscillator circuit
The clock applied to the CLRC632 acts as a time basis for the synchronous system
encoder and decoder. The stability of the clock frequency is an important factor for correct
operation. To obtain highest performance, clock jitter must be as small as possible. This is
best achieved by using the internal oscillator buffer with the recommended circuitry.

If an external clock source is used, the clock signal must be applied to pin OSCIN. In this
case, be very careful in optimizing clock duty cycle and clock jitter. Ensure the clock
quality has been verified. It must meet the specifications described in Section 13.4.5 on
page 106.
Remark: We do not recommend using an external clock source.
9.9 Transmitter pins TX1 and TX2
The signal on pins TX1 and TX2 is the 13.56 MHz energy carrier modulated by an
envelope signal. It can be used to drive an antenna directly, using minimal passive
components for matching and filtering (see Section 15.1 on page 107). To enable this, the
output circuitry is designed with a very low-impedance source resistance. The TxControl
register is used to control the TX1 and TX2 signals.

9.9.2 Antenna operating distance versus power consumption
Using different antenna matching circuits (by varying the supply voltage on the antenna
driver supply pin TVDD), it is possible to find the trade-off between maximum effective
operating distance and power consumption. Different antenna matching circuits are
described in the Application note “MIFARE Design of MFRC500 Matching Circuit and
Antennas”.
9.9.3 Antenna driver output source resistance
The output source conductance of pins TX1 and TX2 can be adjusted between 1 and
100 using the CwConductance register GsCfgCW[5:0] bits.
The output source conductance of pins TX1 and TX2 during the modulation phase can be
adjusted between 1 and 100 using the ModConductance register GsCfgMod[5:0] bits.
The values are relative to the reference resistance (RS(ref)) which is measured during the
production test and stored in the CLRC632 EEPROM. It can be read from the product
information field (see Section 9.2.1 on page 13). The electrical specification can be found

9.9.3.2 Calculating the relative source resistance
The reference source resistance RS(ref) can be calculated using Equation 6.
(6)
The reference source resistance (RS(ref)) during the modulation phase can be calculated
using ModConductance register’s GsCfgMod[5:0].
9.9.3.3 Calculating the effective source resistance
Wiring resistance (RS(wire)): Wiring and bonding add a constant offset to the driver
resistance that is relevant when pins TX1 and TX2 are switched to low-impedance. The
additional resistance for pin TX1 (RS(wire)TX1) can be set approximately as shown in
Equation 7.
(7)
Effective resistance (RSx): The source resistances of the driver transistors (RsMaxP
byte) read from the Product Information Field (see Section 9.2.1 on page 13) are
measured during the production test with CwConductance register’s
GsCfgCW[5:0] = 01h.
To calculate the driver resistance for a specific value set in GsCfgMod[5:0], use
Equation 8.
(8)
9.9.4 Pulse width
The envelope carries the data signal information that is transmitted to the card. It is an
encoded data signal based on the Miller code. In addition, each pause of the Miller
encoded signal is again encoded as a pulse of a fixed width. The width of the pulse is
adjusted using the ModWidth register. The pulse width (tw) is calculated using Equation 9
where the frequency constant (fclk) = 13.56 MHz.

The CLRC632 uses an integrated quadrature demodulation circuit enabling it to detect an

Standard multi-protocol reader solution
The quadrature demodulator uses two different clocks (Q-clock and I-clock) with a
phase-shift of 90 between them. Both resulting subcarrier signals are amplified, filtered
and forwarded to the correlation circuitry. The correlation results are evaluated, digitized
and then passed to the digital circuitry. Various adjustments can be made to obtain
optimum performance for all processing units.
9.10.1 Receiver circuit block diagram
Figure 12 shows the block diagram of the receiver circuit. The receiving process can be
broken down in to several steps. Quadrature demodulation of the 13.56 MHz carrier signal
is performed. To achieve the optimum performance, automatic Q-clock calibration is
recommended (see Section 9.10.2.1 on page 35).
The demodulated signal is amplified by an adjustable amplifier. A correlation circuit
calculates the degree of similarity between the expected and the received signal. The
BitPhase register enables correlation interval position alignment with the received signal’s
bit grid. In the evaluation and digitizer circuitry, the valid bits are detected and the digital
results are sent to the FIFO buffer. Several tuning steps are possible for this circuit.
The signal can be observed on its way through the receiver as shown in Figure 12. One
signal at a time can be routed to pin AUX using the TestAnaSelect register as described in
Section 15.2.2 on page 112.
9.10.2 Receiver operation
In general, the default settings programmed in the StartUp initialization file are suitable for
use with the CLRC632 to MIFARE card data communication. However, in some

The quadrature demodulation concept of the receiver generates a phase signal (I-clock)
and a 90 phase-shifted quadrature signal (Q-clock). To achieve the optimum
demodulator performance, the Q-clock and the I-clock must be phase-shifted by 90. After
the reset phase, a calibration procedure is automatically performed.

Automatic calibration can be set-up to execute at the end of each Transceive command if
bit ClkQCalib = logic 0. Setting bit ClkQCalib = logic 1 disables all automatic calibrations
except after the reset sequence. Automatic calibration can also be triggered by the
software when bit ClkQCalib has a logic 0 to logic 1 transition.
Remark: The duration of the automatic Q-clock calibration is 65 oscillator periods or
approximately 4.8 s.
The ClockQControl register’s ClkQDelay[4:0] value is proportional to the phase-shift
between the Q-clock and the I-clock. The ClkQ180Deg status flag bit is set when the
phase-shift between the Q-clock and the I-clock is greater than 180.
Remark:
• The StartUp configuration file enables automatic Q-clock calibration after a reset
• If bit ClkQCalib = logic 1, automatic calibration is not performed. Leaving this bit set to
logic 1 can be used to permanently disable automatic calibration.
• It is possible to write data to the ClkQDelay[4:0] bits using the microprocessor. The
aim could be to disable automatic calibration and set the delay using the software.
Configuring the delay value using the software requires bit ClkQCalib to have been
previously set to logic 1 and a time interval of at least 4.8 s has elapsed. Each delay
value must be written with bit ClkQCalib set to logic 1. If bit ClkQCalib is logic 0, the
configured delay value is overwritten by the next automatic calibration interval.
9.10.2.2 Amplifier
The demodulated signal must be amplified by the variable amplifier to achieve the best
performance. The gain of the amplifiers can be adjusted using the RxControl1 register
Gain[1:0] bits; see Table 29.

9.10.2.3 Correlation circuitry
The correlation circuitry calculates the degree of matching between the received and an
expected signal. The output is a measure of the amplitude of the expected signal in the
received signal. This is done for both, the Q and I-channels. The correlator provides two
outputs for each of the two input channels, resulting in a total of four output signals.
The correlation circuitry needs the phase information for the incoming card signal for
optimum performance. This information is defined for the microprocessor using the
BitPhase register. This value defines the phase relationship between the transmitter and
receiver clock in multiples of the BitPhase time (tBitPhase) = 1 / 13.56 MHz.
9.10.2.4 Evaluation and digitizer circuitry
The correlation results are evaluated for each bit-half of the Manchester coded signal. The
evaluation and digitizer circuit decides from the signal strengths of both bit-halves, if the
current bit is valid
• If the bit is valid, its value is identified
• If the bit is not valid, it is checked to identify if it contains a bit-collision
Select the following levels for optimal using RxThreshold register bits:
• MinLevel[3:0]: defines the minimum signal strength of the stronger bit-halve’s signal
which is considered valid.
• CollLevel[3:0]: defines the minimum signal strength relative to the amplitude of the
stronger half-bit that has to be exceeded by the weaker half-bit of the Manchester
coded signal to generate a bit-collision. If the signal’s strength is below this value,
logic 1 and logic 0 can be determined unequivocally.
After data transmission, the card is not allowed to send its response before a preset time
period which is called the frame guard time in the ISO/IEC 14443 standard. The length of
this time period is set using the RxWait register’s RxWait[7:0] bits. The RxWait register
defines when the receiver is switched on after data transmission to the card in multiples of
one bit duration.
If bit RcvClkSelI is set to logic 1, the I-clock is used to clock the correlator and evaluation
circuits. If bit RcvClkSelI is set to logic 0, the Q-clock is used.
Remark: It is recommended to use the Q-clock.
9.11 Serial signal switch
The CLRC632 comprises two main blocks:
• digital circuitry: comprising the state machines, encoder and decoder logic etc.
• analog circuitry: comprising the modulator, antenna drivers, receiver and
amplification circuitry
The interface between these two blocks can be configured so that the interface signals
are routed to pins MFIN and MFOUT. This makes it possible to connect the analog part of
one CLRC632 to the digital part of another device.
The serial signal switch can be used to measure MIFARE and ISO/IEC 14443 A as well as
related I-CODE1 and ISO/IEC 15693 signals.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

Two CLRC632 devices configured as described in Table 33 can be connected to each
other using pins MFOUT and MFIN.
Remark: The active antenna concept can only be used at 106 kBd based on
ISO/IEC 14443 A.
9.11.2.2 Driving both RF parts
It is possible to connect both passive and active antennas to a single IC. The passive
antenna pins TX1, TX2 and RX are connected using the appropriate filter and matching
circuit. At the same time an active antenna is connected to pins MFOUT and MFIN. In this
configuration, two RF parts can be driven, one after another, by one microprocessor.
9.12 MIFARE higher baud rates
The MIFARE system is specified with a fixed baud rate of 106 kBd for communication on
the RF interface. The current version of ISO/IEC 14443 A also defines 106 kBd for the
initial phase of a communication between Proximity Integrated Circuit Cards (PICC) and
Proximity Coupling Devices (PCD).
To cover requirements of large data transmissions and to speed up terminal to card
communication, the CLRC632 supports communication at MIFARE higher baud rates in
combination with a microcontroller IC such as the MIFARE ProX.
The MIFARE higher baud rates concept is described in the application note: MIFARE
Implementation of Higher Baud rates Ref. 5. This application covers the integration of the
MIFARE higher baud rates communication concept in current applications.

9.14 MIFARE authentication and Crypto1
The security algorithm used in the MIFARE products is called Crypto1. It is based on a
proprietary stream cipher with a 48-bit key length. To access data on MIFARE cards,
knowledge of the key format is needed. The correct key must be available in the
CLRC632 to enable successful card authentication and access to the card’s data stored in
the EEPROM.
After a card is selected as defined in ISO/IEC 14443 A standard, the user can continue
with the MIFARE protocol. It is mandatory that card authentication is performed.
Crypto1 authentication is a 3-pass authentication which is automatically performed when
the Authent1 and Authent2 commands are executed (see Section 11.7.3 on page 98 and
Section 11.7.4 on page 98).
During the card authentication procedure, the security algorithm is initialized. After a
successful authentication, communication with the MIFARE card is encrypted.
9.14.1 Crypto1 key handling
On execution of the authentication command, the CLRC632 reads the key from the key
buffer. The key is always read from the key buffer and ensures Crypto1 authentication
commands do not require addressing of a key. The user must ensure the correct key is
prepared in the key buffer before triggering card authentication.
The key buffer can be loaded from:
• the EEPROM using the LoadKeyE2 command (see Section 11.7.1 on page 97)
• the microprocessor’s FIFO buffer using the LoadKey command (see Section 11.7.2
on page 97). This is shown in Figure 15.

9.14.2 Authentication procedure
The Crypto1 security algorithm enables authentication of MIFARE cards. To obtain valid
authentication, the correct key has to be available in the key buffer of the CLRC632. This
can be ensured as follows:
1. Load the internal key buffer by using the LoadKeyE2 (see Section 11.7.1 on page 97)
or the LoadKey (see Section 11.7.2 on page 97) commands.
2. Start the Authent1 command (see Section 11.7.3 on page 98). When finished, check
the error flags to obtain the command execution status.
3. Start the Authent2 command (see Section 11.7.4 on page 98). When finished, check
the error flags and bit Crypto1On to obtain the command execution status.
10. CLRC632 registers
10.1 Register addressing modes
Three methods can be used to operate the CLRC632:
• initiating functions and controlling data by executing commands
• configuring the functional operation using a set of configuration bits
• monitoring the state of the CLRC632 by reading status flags
The commands, configuration bits and flags are accessed using the microprocessor
interface. The CLRC632 can internally address 64 registers using six address lines.
10.1.1 Page registers
The CLRC632 register set is segmented into eight pages contain eight registers each. A
Page register can always be addressed, irrespective of which page is currently selected.
10.1.2 Dedicated address bus
When using the CLRC632 with the dedicated address bus, the microprocessor defines
three address lines using address pins A0, A1 and A2. This enables addressing within a
page. To switch between registers in different pages a paging mechanism needs to be
used.
Table 36 shows how the register address is assembled.
10.1.3 Multiplexed address bus
The microprocessor may define all six address lines at once using the CLRC632 with a
multiplexed address bus. In this case either the paging mechanism or linear addressing
can be used.
Table 37 shows how the register address is assembled.

R/W read and write These bits can be read and written by the microprocessor.
Since they are only used for control, their content is not
influenced by internal state machines.
Example: TimerReload register may be read and written by
the microprocessor. It will also be read by internal state
machines but never changed by them.
D dynamic These bits can be read and written by the microprocessor.
Nevertheless, they may also be written automatically by
internal state machines.
Example: the Command register changes its value
automatically after the execution of the command.
R read only These registers hold flags which have a value determined by
internal states only.
Example: the ErrorFlag register cannot be written externally
but shows internal states.
W write only These registers are used for control only. They may be written
by the microprocessor but cannot be read. Reading these
registers returns an undefined value.
Example: The TestAnaSelect register is used to determine the
signal on pin AUX however, it is not possible to read its

11. CLRC632 command set
CLRC632 operation is determined by an internal state machine capable of performing a
command set. The commands can be started by writing the command code to the
Command register. Arguments and/or data necessary to process a command are mainly
exchanged using the FIFO buffer.
• Each command needing a data stream (or data byte stream) as an input immediately
processes the data in the FIFO buffer
• Each command that requires arguments only starts processing when it has received
the correct number of arguments from the FIFO buffer
• The FIFO buffer is not automatically cleared at the start of a command. It is, therefore,
possible to write command arguments and/or the data bytes into the FIFO buffer
before starting a command.
• Each command (except the StartUp command) can be interrupted by the
microprocessor writing a new command code to the Command register e.g. the Idle
command.

11.1.1 Basic states
11.1.2 StartUp command 3Fh
Remark: This command can only be activated by a Power-On or Hard reset.
The StartUp command runs the reset and initialization phases. It does not need or return,
any data. It cannot be activated by the microprocessor but is automatically started after
one of the following events:
• Power-On Reset (POR) caused by power-up on pin DVDD
• POR caused by power-up on pin AVDD
• Negative edge on pin RSTPD
The reset phase comprises an asynchronous reset and configuration of certain register
bits. The initialization phase configures several registers with values stored in the
EEPROM.
When the StartUp command finishes, the Idle command is automatically executed.
Remark:
• The microprocessor must not write to the CLRC632 while it is still executing the
StartUp command. To avoid this, the microprocessor polls for the Idle command to
determine when the initialization phase has finished; see Section 9.7.4 on page 30.
• When the StartUp command is active, it is only possible to read from the Page 0
register.
• The StartUp command cannot be interrupted by the microprocessor.
11.1.3 Idle command 00h
The Idle command switches the CLRC632 to its inactive state where it waits for the next
command. It does not need or return, any data.
The device automatically enters the idle state when a command finishes. When this
happens, the CLRC632 sends an interrupt request by setting bit IdleIRq. When triggered
by the microprocessor, the Idle command can be used to stop execution of all other
commands (except the StartUp command) but this does not generate an interrupt request
(IdleIRq).
Remark: Stopping command execution with the Idle command does not clear the FIFO
buffer.

11.2 Commands for ISO/IEC 14443 A card communication
The CLRC632 is a fully ISO/IEC 14443 A, ISO/IEC 14443 B, ISO/IEC 15693 and
I-CODE1 compliant reader IC. This enables the command set to be more flexible and
generalized when compared to dedicated MIFARE or I-CODE1 reader ICs. Section 11.2.1
to Section 11.2.5 describe the command set for ISO/IEC 14443 A card communication
and related communication protocols.
11.2.1 Transmit command 1Ah
The Transmit command reads data from the FIFO buffer and sends it to the transmitter. It
does not return any data. The Transmit command can only be started by the
microprocessor.
11.2.1.1 Using the Transmit command
To transmit data, one of the following sequences can be used:
1. All data to be transmitted to the card is written to the FIFO buffer while the Idle
command is active. Then the command code for the Transmit command is written to
the Command register.
Remark: This is possible for transmission of a data stream up to 64 bytes.
2. The command code for the Transmit command is stored in the Command register.
Since there is not any data available in the FIFO buffer, the command is only enabled
but transmission is not activated. Data transmission starts when the first data byte is
written to the FIFO buffer. To generate a continuous data stream on the RF interface,
the microprocessor must write the subsequent data bytes into the FIFO buffer in time.
Remark: This allows transmission of any data stream length but it requires data to be
written to the FIFO buffer in time.
3. Part of the data transmitted to the card is written to the FIFO buffer while the Idle
command is active. Then the command code for the Transmit command is written to
the Command register. While the Transmit command is active, the microprocessor
can send further data to the FIFO buffer. This is then appended by the transmitter to
the transmitted data stream.
Remark: This allows transmission of any data stream length but it requires data to be
written to the FIFO buffer in time.
When the transmitter requests the next data byte to ensure the data stream on the RF
interface is continuous and the FIFO buffer is empty, the Transmit command automatically
terminates. This causes the internal state machine to change its state from transmit to
idle.
When the data transmission to the card is finished, the TxIRq flag is set by the CLRC632
to indicate to the microprocessor transmission is complete.
Remark: If the microprocessor overwrites the transmit code in the Command register
with another command, transmission stops immediately on the next clock cycle. This can
produce output signals that are not in accordance with ISO/IEC 14443 A.

11.2.1.2 RF channel redundancy and framing
Each ISO/IEC 14443 A transmitted frame consists of a Start Of Frame (SOF) pattern,
followed by the data stream and is closed by an End Of Frame (EOF) pattern. These
different phases of the transmission sequence can be monitored using the PrimaryStatus
register ModemState[2:0] bit; see Section 11.2.4 on page 85.
Depending on the setting of the ChannelRedundancy register bit TxCRCEn, the CRC is
calculated and appended to the data stream. The CRC is calculated according to the
settings in the ChannelRedundancy register. Parity generation is handled according to the
ChannelRedundancy register ParityEn and ParityOdd bits settings.
11.2.1.3 Transmission of bit oriented frames
The transmitter can be configured to send an incomplete last byte. To achieve this the
BitFraming register’s TxLastBits[2:0] bits must be set at above zero (for example, 1). This
is shown in Figure 16.
Figure 16 shows the data stream if bit ParityEn is set in the ChannelRedundancy register.
All fully transmitted bytes are followed by a parity check bit but the incomplete byte is not
followed by a parity check bit. After transmission, the TxLastBits[2:0] bits are automatically
cleared.
Remark: If the TxLastBits[2:0] bits are not equal to zero, CRC generation must be
disabled. This is done by clearing the ChannelRedundancy register TxCRCEn bit.
11.2.1.4 Transmission of frames with more than 64 bytes
To generate frames of more than 64 bytes, the microprocessor must write data to the
FIFO buffer while the Transmit command is active. The state machine checks the FIFO
buffer status when it starts transmitting the last bit of the data stream; the check time is
marked in Figure 17 with arrows.

NXP Semiconductors CLRC632
Standard multi-protocol reader solution
As long as the internal accept further data signal is logic 1, further data can be written to
the FIFO buffer. The CLRC632 appends this data to the data stream transmitted using the
RF interface.
If the internal accept further data signal is logic 0, the transmission terminates. All data
written to the FIFO buffer after accept further data signal was set to logic 0 is not
transmitted, however, it remains in the FIFO buffer.
Remark: If parity generation is enabled (ParityEn = logic 1), the parity bit is the last bit
transmitted. This delays the accept further data signal by a duration of one bit.
If the TxLastBits[2:0] bits are not zero, the last byte is not transmitted completely. Only the
number of bits set by TxLastBits[2:0], starting with the least significant bit are transmitted.
This means that the internal state machine has to check the FIFO buffer status at an
earlier point in time; see Figure 18.
Since in this example TxLastBits[2:0] = 4, transmission stops after bit 3 is transmitted and
the frame is completed with an EOF, if configured.

Figure 18 also shows write access to the FIFOData register just before the FIFO buffer’s
status is checked. This leads to FIFO empty state being held LOW which keeps the
accept further data active. The new byte written to the FIFO buffer is transmitted using the
RF interface.
Accept further data is only changed by the check FIFO empty function. This function
verifies FIFO empty for one bit duration before the last expected bit transmission.
11.2.2 Receive command 16h
The Receive command activates the receiver circuitry. All data received from the RF
interface is written to the FIFO buffer. The Receive command can be started either using
the microprocessor or automatically during execution of the Transceive command.
Remark: This command can only be used for test purposes since there is no timing
relationship to the Transmit command.
11.2.2.1 Using the Receive command
After starting the Receive command, the internal state machine decrements to the RxWait
register value on every bit-clock. The analog receiver circuitry is prepared and activated
from 3 down to 1. When the counter reaches 0, the receiver starts monitoring the incoming
signal at the RF interface.
When the signal strength reaches a level higher than the RxThreshold register
MinLevel[3:0] bits value, it starts decoding. The decoder stops when the signal can longer
be detected on the receiver input pin RX. The decoder sets bit RxIRq indicating receive
termination.
The different phases of the receive sequence are monitored using the PrimaryStatus
register ModemState[2:0] bits; see Section 11.2.4 on page 85.
Remark: Since the counter values from 3 to 0 are needed to initialize the analog receiver
circuitry, the minimum value for RxWait[7:0] is 3.
11.2.2.2 RF channel redundancy and framing
The decoder expects the SOF pattern at the beginning of each data stream. When the
SOF is detected, it activates the serial-to-parallel converter and gathers the incoming data
bits. Every completed byte is forwarded to the FIFO buffer.

If an EOF pattern is detected or the signal strength falls below the RxThreshold register
MinLevel[3:0] bits setting, both the receiver and the decoder stop. Then the Idle command
is entered and an appropriate response for the microprocessor is generated (interrupt
request activated, status flags set).
When the ChannelRedundancy register bit RxCRCEn is set, a CRC block is expected.
The CRC block can be one byte or two bytes depending on the ChannelRedundancy
register CRC8 bit setting.
Remark: If the CRC block received is correct, it is not sent to the FIFO buffer. This is
realized by shifting the incoming data bytes through an internal buffer of either one or two
bytes (depending on the defined CRC). The CRC block remains in this internal buffer.
Consequently, all data bytes in the FIFO buffer are delayed by one or two bytes. If the
CRC fails, all received bytes are sent to the FIFO buffer including the faulty CRC.
If ParityEn is set in the ChannelRedundancy register, a parity bit is expected after each
byte. If ParityOdd = logic 1, the expected parity is odd, otherwise even parity is expected.
11.2.2.3 Collision detection
If more than one card is within the RF field during the card selection phase, they both
respond simultaneously. The CLRC632 supports the algorithm defined in
ISO/IEC 14443 A to resolve card serial number data collisions by performing the
anti-collision procedure. The basis for this procedure is the ability to detect bit-collisions.
Bit-collision detection is supported by the Manchester coding bit encoding scheme used in
the CLRC632. If in the first and second half-bit of a subcarrier, modulation is detected,
instead of forwarding a 1-bit or 0-bit, a bit-collision is indicated. The CLRC632 uses the
RxThreshold register CollLevel[3:0] bits setting to distinguish between a 1-bit or 0-bit and
a bit-collision. If the amplitude of the half-bit with smaller amplitude is larger than that
defined by the CollLevel[3:0] bits, the CLRC632 flags a bit-collision using the error flag
CollErr. If a bit-collision is detected in a parity bit, the ParityErr flag is set.
On a detected collision, the receiver continues receiving the incoming data stream. In the
case of a bit-collision, the decoder sends logic 1 at the collision position.
Remark: As an exception, if bit ZeroAfterColl is set, all bits received after the first
bit-collision are forced to zero, regardless whether a bit-collision or an unequivocal state
has been detected. This feature makes it easier for the control software to perform the
anti-collision procedure as defined in ISO/IEC 14443 A.
When the first bit collision in a frame is detected, the bit-collision position is stored in the
CollPos register.
Table 139 shows the collision positions.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

Parity bits are not counted in the CollPos register because bit-collisions in parity bit occur
after bit-collisions in the data bits. If a collision is detected in the SOF, a frame error is
flagged and no data is sent to the FIFO buffer. In this case, the receiver continues to
monitor the incoming signal. It generates the correct notifications to the microprocessor
when the end of the faulty input stream is detected. This helps the microprocessor to
determine when it is next allowed to send data to the card.
11.2.2.4 Receiving bit oriented frames
The receiver can manage byte streams with incomplete bytes which result in bit-oriented
frames. To support this, the following values may be used:
• BitFraming register’s RxAlign[2:0] bits select a bit offset for the first incoming byte. For
example, if RxAlign[2:0] = 3, the first 5 bits received are forwarded to the FIFO buffer.
Further bits are packed into bytes and forwarded. After reception, RxAlign[2:0] is
automatically cleared. If RxAlign[2:0] = logic 0, all incoming bits are packed into one
byte.
• RxLastBits[2:0] returns the number of bits valid in the last received byte. For example,
if RxLastBits[2:0] evaluates to 5 bits at the end of the received command, the 5 least
significant bits are valid. If the last byte is complete, RxLastBits[2:0] evaluates to zero.
RxLastBits[2:0] is only valid if a frame error is not indicated by the FramingErr flag. If
RxAlign[2:0] is not zero and ParityEn is active, the first parity bit is ignored and not
checked.

The events which can set error flags are shown in Table 140.

11.2.3 Transceive command 1Eh
The Transceive command first executes the Transmit command (see Section 11.2.1 on
page 79) and then starts the Receive command (see Section 11.2.2 on page 82). All data
transmitted is sent using the FIFO buffer and all data received is written to the FIFO buffer.
The Transceive command can only be started by the microprocessor.
Remark: To adjust the timing relationship between transmitting and receiving, use the
RxWait register. This register is used to define the time delay between the last bit
transmitted and activation of the receiver. In addition, the BitPhase register determines the
phase-shift between the transmitter and receiver clock.
11.2.4 States of the card communication
The status of the transmitter and receiver state machine can be read from bits
ModemState[2:0] in the PrimaryStatus register.

11.3 I-CODE1 and ISO/IEC 15693 label communication commands
The CLRC632 is a fully ISO/IEC 14443 A, ISO/IEC 14443 B, ISO/IEC 15693 and
I-CODE1 compliant reader IC. This enables the command set to be more flexible and
generalized when compared to dedicated MIFARE or I-CODE1 reader ICs. Section 11.3.1
to Section 11.3.5 give an overview of the command set for I-CODE1 and ISO/IEC 15693
card communication and related communication protocols.
11.3.1 Transmit command 1Ah
The Transmit command reads data from the FIFO buffer and sends it to the transmitter. It
does not return any data. The Transmit command can only be started by the
microprocessor.
11.3.1.1 Using the Transmit command
To transmit data, one of the following sequences can be used:
1. All data to be transmitted to the label is written to the FIFO buffer while the Idle
command is active. Then the command code for the Transmit command is written to
the Command register.
Remark: This is possible for transmission of a data stream up to 64 bytes long.
2. The command code for the Transmit command is stored in the Command register.
Since there is not any data available in the FIFO buffer, the command is only enabled
but transmission is not triggered. Data transmission starts when the first data byte is
written to the FIFO buffer. To generate a continuous data stream on the RF interface,
the microprocessor must write the subsequent data bytes into the FIFO buffer in time.
Remark: This allows transmission of any data stream length but it requires data to be
written to the FIFO buffer in time.
3. Part of the data transmitted to the label is written to the FIFO buffer while the Idle
command is active. Then the command code for the Transmit command is written to
the Command register. While the Transmit command is active, the microprocessor
can send further data to the FIFO buffer. This is then appended by the transmitter to
the transmitted data stream.
Remark: This allows transmission of any data stream length but it requires data to be
written to the FIFO buffer in time.
When the transmitter requests the next data byte, to ensure that the data stream on the
RF interface is continuous and the FIFO buffer is empty, the Transmit command
automatically terminates. This causes the internal state machine to change its state from
transmit to idle. When the data transmission to the label is finished, the TxIRq flag is set
by the CLRC632 to indicate transmission is complete to the microprocessor.
Remark: If the microprocessor overwrites the transmit code in the Command register
with another command, transmission stops immediately on the next clock cycle. This can
produce output signals that do not comply with the ISO/IEC 15693 standard or the
I-CODE1 protocol.

11.3.1.2 RF channel redundancy and framing
Each transmitted ISO/IEC 15693 frame consists of a Start Of Frame (SOF) pattern,
followed by the data stream and is closed by an End Of Frame (EOF) pattern. All
I-CODE1 command frames consists of a start pulse followed by the data stream. The
I-CODE1 commands have a fixed length and do not need an EOF. The phases of the
transmission sequence are monitored using the PrimaryStatus register’s ModemState[2:0]
bits; see Section 11.2.4 on page 85.
Depending on the ChannelRedundancy register TxCRCEn bit setting, the CRC is
calculated and appended to the data stream. The CRC is calculated using the
ChannelRedundancy register settings.
11.3.1.3 Transmission of frames of more than 64 bytes
To generate frames of more than 64 bytes of data, the microprocessor has to write data to
the FIFO buffer while the Transmit command is active. The state machine checks the
FIFO buffer status when it starts transmitting the last bit of the data stream (the check time
is shown in Figure 20 with arrows).
As long as the internal accept further data signal is logic 1 further data can be written to
the FIFO buffer. The CLRC632 appends this data to the data stream transmitted using the
RF interface.
If the internal accept further data signal is logic 0 the transmission terminates. All data
written to the FIFO buffer after accept further data signal was set to logic 0 is not
transmitted, however, it remains in the FIFO buffer.
11.3.2 Receive command 16h
The Receive command activates the receiver circuitry. All data received from the RF
interface is written to the FIFO buffer. The Receive command can be started either by the
microprocessor or automatically during execution of the Transceive command.

Standard multi-protocol reader solution
Remark: This command may be used for test purposes only, since there is no timing
relation to the Transmit command.
11.3.2.1 Using the Receive command
After starting the Receive command the internal state machine decrements the RxWait
register value on every bit-clock. The analog receiver circuitry is prepared and activated
from 3 down to 1. When the counter reaches 0, the receiver starts monitoring the incoming
signal using the RF interface. If the signal strength reaches a level above the value set in
the RxThreshold register’s MinLevel[3:0] bits, the receiver starts decoding. The decoder
stops when the signal cannot be detected on the receiver input pin RX. The decoder sets
the RxIRq flag bit to indicate that the operation has finished.
The receive sequence phases can be monitored using bits ModemStatus[2:0] in the
PrimaryStatus register; see Section 11.2.4 on page 85.
Remark: The minimum value for RxWait[7:0] is 3 because counter values from 3 to 0 are
needed to initialize the analog receiver circuitry.
11.3.2.2 RF channel redundancy and framing
In ISO/IEC 15693 mode, the decoder expects a SOF pattern at the beginning of each data
stream. When a SOF is detected, it activates the serial-to-parallel converter and gathers
the incoming data bits. If an EOF pattern (ISO/IEC 15693) is detected or the signal
strength falls below the MinLevel value, the receiver and the decoder stop, the Idle
command is entered and an appropriate response for the microprocessor is generated
(interrupt request activated, status flags set).
In I-CODE1 mode, the decoder does not expect a SOF pattern at the beginning of each
data stream. It activates the serial-to-parallel converter on the first received bit of the data.
Every full byte is then sent to the FIFO buffer.
If ChannelRedundancy register bit RxCRCEn is set a CRC block is expected. The CRC
block may be one byte or two bytes based on the ChannelRedundancy register’s CRC8
bit.
Remark: If it is correct, the CRC block is not forwarded to the FIFO buffer. The CRC is
realized by shifting the incoming data bytes through an internal buffer of one or two bytes
(depending on the defined CRC). The CRC block remains in this internal buffer.
Consequently, all data bytes in the FIFO buffer are delayed by one or two bytes. If the
CRC fails, all bytes received are forwarded to the FIFO buffer (including the faulty CRC).
11.3.2.3 Collision detection
If more than one label is within the RF field during the label selection phase, they will
respond simultaneously. The CLRC632 supports the algorithm defined in ISO/IEC 15693
as well as the I-CODE1 anti-collision algorithm to resolve label serial number data
collisions using the anti-collision procedure. The basis for this procedure is the ability to
detect bit-collisions.
Bit-collision detection is supported by the Manchester coding bit encoding scheme used. If
in the first and second half-bit of a bit a subcarrier modulation is detected, instead of
forwarding a 1-bit or a 0-bit, a bit-collision is flagged.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors CLRC632
Standard multi-protocol reader solution
To distinguish between a 1-bit or 0-bit from a bit-collision, the RxThreshold register’s
CollLevel[3:0] value is used. If the amplitude of the half-bit with smaller amplitude is larger
than defined by CollLevel[3:0], a bit-collision is flagged by setting the CollErr error flag.
The receiver continues receiving the incoming data stream independently from the
detected collision. In case of a bit-collision, the decoder forwards logic 1 at the collision
position.
Remark: As an exception, if bit ZeroAfterColl is set, all bits received after the first
bit-collision are forced to zero, regardless of whether a bit-collision or an unequivocal
state has been detected. This feature makes it easier for the software to carry out the
anti-collision procedure as defined in ISO/IEC 15693.
When the first bit-collision in a frame is detected, the bit position of the collision is stored in
the CollPos register.
The collision positions are shown in Table 145.
If a collision is detected in the SOF, a frame error is reported and no data is sent to the
FIFO buffer. In this case the receiver continues to monitor the incoming signal and
generates the correct notifications to the microprocessor when the end of the faulty input
stream is detected. This helps the microprocessor to determine the time when it is next
allowed to send data to the label.

The Transceive command first executes the Transmit command (see Section 11.2.1 on
page 79) and then starts the Receive command (see Section 11.2.2 on page 82). All data

11.4 EEPROM commands
11.4.1 WriteE2 command 01h
The WriteE2 command interprets the first two bytes in the FIFO buffer as the EEPROM
start byte address. Any further bytes are interpreted as data bytes and are programmed
into the EEPROM, starting from the given EEPROM start byte address. This command
does not return any data.
The WriteE2 command can only be started by the microprocessor. It will not stop
automatically but has to be stopped explicitly by the microprocessor by issuing the Idle
command.
11.4.1.1 Programming process
One byte up to 16-byte can be programmed into the EEPROM during a single
programming cycle. The time needed is approximately 5.8 ms.
The state machine copies all the prepared data bytes to the FIFO buffer and then to the
EEPROM input buffer. The internal EEPROM input buffer is 16 bytes long which is equal
to the block size of the EEPROM. A programming cycle is started if the last position of the
EEPROM input buffer is written or if the last byte of the FIFO buffer has been read.
The E2Ready flag remains logic 0 when there are unprocessed bytes in the FIFO buffer or
the EEPROM programming cycle is still in progress. When all the data from the FIFO
buffer are programmed into the EEPROM, the E2Ready flag is set to logic 1. Together
with the rising edge of E2Ready the TxIRq interrupt request flag shows logic 1. This can
be used to generate an interrupt when programming of all data is finished.
Remark: During the E2PROM programming indicated by E2Ready = logic 0, the WriteE2
command cannot be stopped using any other command.
Once E2Ready = logic 1, the WriteE2 command can be stopped by the microprocessor by
sending the Idle command.

11.4.1.2 Timing diagram
Figure 22 shows programming five bytes into the EEPROM.
Assuming that the CLRC632 finds and reads byte 0 before the microprocessor is able to
write byte 1 (tprog,del = 300 ns). This causes the CLRC632 to start the programming cycle
(tprog), which takes approximately 5.8 ms to complete. In the meantime, the
microprocessor stores byte 1 to byte 4 in the FIFO buffer.
If the EEPROM start byte address is 16Ch then byte 0 is stored at that address. The
CLRC632 copies the subsequent data bytes into the EEPROM input buffer. Whilst
copying byte 3, it detects that this data byte has to be programmed at the EEPROM byte
address 16Fh. As this is the end of the memory block, the CLRC632 automatically starts a
programming cycle.
Next, byte 4 is programmed at the EEPROM byte address 170h. As this is the last data
byte, the E2Ready and TxIRq flags are set indicating the end of the EEPROM
programming activity.
Although all data has been programmed into the E2PROM, the CLRC632 stays in the
WriteE2 command. Writing more data to the FIFO buffer would lead to another EEPROM
programming cycle continuing from EEPROM byte address 171h. The command is
stopped using the Idle command.
11.4.1.3 WriteE2 command error flags
Programming is restricted for EEPROM block 0 (EEPROM byte address 00h to 0Fh). If
you program these addresses, the AccessErr flag is set and a programming cycle is not
started.
Addresses above 1FFh are taken modulo 200h; see Section 9.2 on page 12 for the
EEPROM memory organization.

11.4.2 ReadE2 command 03h
The ReadE2 command interprets the first two bytes stored in the FIFO buffer as the
EEPROM starting byte address. The next byte specifies the number of data bytes
returned.
When all three argument bytes are available in the FIFO buffer, the specified number of
data bytes is copied from the EEPROM into the FIFO buffer, starting from the given
EEPROM starting byte address.
The ReadE2 command can only be triggered by the microprocessor and it automatically
stops when all data has been copied.
11.4.2.1 ReadE2 command error flags
Reading is restricted to EEPROM blocks 8h to 1Fh (key memory area). Reading from
these addresses sets the flag AccessErr = logic 1.
Addresses above 1FFh are taken as modulo 200h; see Section 9.2 on page 12 for the
EEPROM memory organization.
11.5 Diverse commands
11.5.1 LoadConfig command 07h
The LoadConfig command interprets the first two bytes found in the FIFO buffer as the
EEPROM starting byte address. When the two argument bytes are available in the FIFO
buffer, 32 bytes from the EEPROM are copied into the Control and other relevant
registers, starting at the EEPROM starting byte address. The LoadConfig command can
only be started by the microprocessor and it automatically stops when all relevant
registers have been copied.
11.5.1.1 Register assignment
The 32 bytes of EEPROM content are written to the CLRC632 registers 10h to register
2Fh; see Section 9.2 on page 12 for the EEPROM memory organization.
Remark: The procedure for the register assignment is the same as it is for the startup
initialization (see Section 9.7.3 on page 30). The difference is, the EEPROM starting byte
address for the startup initialization is fixed to 10h (block 1, byte 0). However, it can be
chosen with the LoadConfig command.

11.5.1.2 Relevant LoadConfig command error flags
Valid EEPROM starting byte addresses are between 10h and 60h.
Copying from block 8h to 1Fh (keys) is restricted. Reading from these addresses sets the
flag AccessErr = logic 1.
Addresses above 1FFh are taken as modulo 200h; see Section 9.2 on page 12 for the
EEPROM memory organization.
11.5.2 CalcCRC command 12h
The CalcCRC command takes all the data from the FIFO buffer as the input bytes for the
CRC coprocessor. All data stored in the FIFO buffer before the command is started is
processed.
This command does not return any data to the FIFO buffer but the content of the CRC can
be read using the CRCResultLSB and CRCResultMSB registers.
The CalcCRC command can only be started by the microprocessor and it does not
automatically stop. It must be stopped by the microprocessor sending the Idle command.
If the FIFO buffer is empty, the CalcCRC command waits for further input before
proceeding.
11.5.2.1 CRC coprocessor settings
Table 153 shows the parameters that can be configured for the CRC coprocessor.
The CRC polynomial for the 8-bit CRC is fixed to x8 + x4 + x3 + x2 + 1.
The CRC polynomial for the 16-bit CRC is fixed to x16 + x12 + x5 + 1.
11.5.2.2 CRC coprocessor status flags
The CRCReady status flag indicates that the CRC coprocessor has finished processing
all the data bytes in the FIFO buffer. When the CRCReady flag is set to logic 1, an
interrupt is requested which sets the TxIRq flag. This supports interrupt driven use of the
CRC coprocessor.
When CRCReady and TxIRq flags are set to logic 1 the content of the CRCResultLSB
and CRCResultMSB registers and the CRCErr flag are valid. The CRCResultLSB and

11.6 Error handling during command execution
If an error is detected during command execution, the PrimaryStatus register Err flag is
set. The microprocessor can evaluate the status flags in the ErrorFlag register to get
information about the cause of the error.
11.7 MIFARE security commands
11.7.1 LoadKeyE2 command 0Bh
The LoadKeyE2 command interprets the first two bytes found in the FIFO buffer as the
EEPROM starting byte address. The EEPROM bytes starting from the given starting byte
address are interpreted as the key when stored in the correct key format as described in
Section 9.2.3.1 “Key format” on page 18. When both argument bytes are available in the
FIFO buffer, the command executes.
The LoadKeyE2 command can only be started by the microprocessor and it automatically
stops after copying the key from the EEPROM to the key buffer.
11.7.1.1 Relevant LoadKeyE2 command error flags
If the key format is incorrect (see Section 9.2.3.1 “Key format” on page 18) an undefined
value is copied into the key buffer and the KeyErr flag is set.

The LoadKey command interprets the first twelve bytes it finds in the FIFO buffer as the
key when stored in the correct key format as described in Section 9.2.3.1 “Key format” on
page 18. When the twelve argument bytes are available in the FIFO buffer they are
checked and, if valid, are copied into the key buffer.
The LoadKey command can only be started by the microprocessor and it automatically
stops after copying the key from the FIFO buffer to the key buffer.
11.7.2.1 Relevant LoadKey command error flags
All bytes requested are copied from the FIFO buffer to the key buffer. If the key format is
not correct (see Section 9.2.3.1 “Key format” on page 18) an undefined value is copied
into the key buffer and the KeyErr flag is set.
11.7.3 Authent1 command 0Ch
The Authent1 command is a special Transceive command; it sends six argument bytes to
the card. The card’s response is not sent to the microprocessor, it is used instead to
authenticate the card to the CLRC632 and vice versa.
The Authent1 command can be triggered only by the microprocessor. The sequence of
states for this command are the same as those for the Transceive command; see
Section 11.2.3 on page 85.
11.7.4 Authent2 command 14h
The Authent2 command is a special Transceive command. It does not need any argument
byte, however all the data needed to be sent to the card is assembled by the CLRC632.
The card response is not sent to the microprocessor but is used to authenticate the card
to the CLRC632 and vice versa.
The Authent2 command can only be started by the microprocessor. The sequence of
states for this command are the same as those for the Transceive command; see

11.7.4.1 Authent2 command effects
If the Authent2 command is successful, the authenticity of card and the CLRC632 are
proved. This automatically sets the Crypto1On control bit. When bit Crypto1On = logic 1,
all further card communication is encrypted using the Crypto1 security algorithm. If the
Authent2 command fails, bit Crypto1On is cleared (Crypto1On = logic 0).
Remark: The Crypto1On flag can only be set by a successfully executed Authent2
command and not by the microprocessor. The microprocessor can clear bit Crypto1On to
continue with unencrypted (plain) card communication.
Remark: The Authent2 command must be executed immediately after a successful
Authent1 command; see Section 11.7.3 “Authent1 command 0Ch”. In addition, the keys
stored in the key buffer and those on the card must match.

15.1.2 Circuit description
The matching circuit consists of an EMC low-pass filter (L0 and C0), matching circuitry
(C1 and C2), a receiver circuit (R1, R2, C3 and C4) and the antenna itself.
Refer to the following application notes for more detailed information about designing and
tuning an antenna.
• MICORE reader IC family; Directly Matched Antenna Design Ref. 1
• MIFARE (14443 A) 13.56 MHz RFID Proximity Antennas Ref. 2.
15.1.2.1 EMC low-pass filter
The MIFARE system operates at a frequency of 13.56 MHz. This frequency is generated
by a quartz oscillator to clock the CLRC632. It is also the basis for driving the antenna
using the 13.56 MHz energy carrier. This not only causes power emissions at 13.56 MHz,
it also emits power at higher harmonics. International EMC regulations define the
amplitude of the emitted power over a broad frequency range. To meet these regulations,
appropriate filtering of the output signal is required.
A multilayer board is recommended to implement a low-pass filter as shown in Figure 27.
The low-pass filter consists of the components L0 and C0. The recommended values are
given in Application notes MICORE reader IC family; Directly Matched Antenna Design
Ref. 1 and MIFARE (14443 A) 13.56 MHz RFID Proximity Antennas Ref. 2.
Remark: To achieve best performance, all components must be at least equal in quality to
those recommended.
Remark: The layout has a major influence on the overall performance of the filter.
15.1.2.2 Antenna matching
Due to the impedance transformation of the low-pass filter, the antenna coil has to be
matched to a given impedance. The matching elements C1 and C2 can be estimated and
have to be fine tuned depending on the design of the antenna coil.
The correct impedance matching is important to ensure optimum performance. The
overall quality factor has to be considered to guarantee a proper ISO/IEC 14443 A and
ISO/IEC 14443 B communication schemes. Environmental influences have to considered
and common EMC design rules.
Refer to Application notes MICORE reader IC family; Directly Matched Antenna Design
Ref. 1 and MIFARE (14443 A) 13.56 MHz RFID Proximity Antennas Ref. 2 for details.
Remark: Do not exceed the current limits (IDD(TVDD)), otherwise the chip might be
destroyed.
Remark: The overall 13.56 MHz RFID proximity antenna design in combination with the
CLRC632 IC does not require any specialist RF knowledge. However, all relevant
parameters have to be considered to guarantee optimum performance and international
EMC compliance.
15.1.2.3 Receiver circuit
The internal receiver of the CLRC632 makes use of both subcarrier load modulation
side-bands. No external filtering is required.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

It is recommended to use the internally generated VMID potential as the input potential for
pin RX. This VMID DC voltage level has to be coupled to pin RX using resistor (R2). To
provide a stable DC reference voltage, a capacitor (C4) must be connected between
VMID and ground.
The AC voltage divider of R1 + C3 and R2 has to be designed taking in to account the AC
voltage limits on pin RX. Depending on the antenna coil design and the impedance,
matching the voltage at the antenna coil will differ. Therefore the recommended way to
design the receiver circuit is to use the given values for R1, R2, and C3; refer to
Application note; MIFARE (14443 A) 13.56 MHz RFID Proximity Antennas Ref. 2. The
voltage on pin RX can be altered by varying R1 within the given limits.
Remark: R2 is AC connected to ground using C4.
15.1.2.4 Antenna coil
The precise calculation of the antenna coil’s inductance is not practicable but the
inductance can be estimated using Equation 10. We recommend designing an antenna
that is either circular or rectangular.
(10)
• l1 = length of one turn of the conductor loop
• D1 = diameter of the wire or width of the PCB conductor, respectively
• K = antenna shape factor (K = 1.07 for circular antennas and K = 1.47 for square
antennas)
• N1 = number of turns
• ln = natural logarithm function
The values of the antenna inductance, resistance, and capacitance at 13.56 MHz depend
on various parameters such as:
• antenna construction (type of PCB)
• thickness of conductor
• distance between the windings
• shielding layer
• metal or ferrite in the near environment
Therefore a measurement of these parameters under real life conditions or at least a
rough measurement and a tuning procedure is highly recommended to guarantee a
reasonable performance. Refer to Application notes MICORE reader IC family; Directly
Matched Antenna Design Ref. 1 and MIFARE (14443 A) 13.56 MHz RFID Proximity
Antennas Ref. 2 for details.

15.2 Test signals
The CLRC632 allows different kinds of signal measurements. These measurements can
be used to check the internally generated and received signals using the serial signal
switch as described in Section 9.11 on page 37.
In addition, the CLRC632 enables users to select between:
• internal analog signals for measurement on pin AUX
• internal digital signals for observation on pin MFOUT (based on register selections)
These measurements can be helpful during the design-in phase to optimize the receiver’s
behavior, or for test purposes.
15.2.1 Measurements using the serial signal switch
Using the serial signal switch on pin MFOUT, data is observed that is sent to the card or
received from the card. Table 174 gives an overview of the different signals available.
Remark: The routing of the Manchester or the Manchester with subcarrier signal to pin
MFOUT is only possible at 106 kBd based on ISO/IEC 14443 A.
15.2.1.1 TX control
Figure 28 shows as an example of an ISO/IEC 14443 A communication.
The signal is measured on pin MFOUT using the serial signal switch to control the data
sent to the card. Setting the flag MFOUTSelect[2:0] = 3 sends the data to the card coded
as NRZ. Setting MFOUTSelect[2:0] = 2 shows the data as a Miller coded signal.
The RFOut signal is measured directly on the antenna and gives the RF signal pulse
shape. Refer to Application note Directly matched Antenna - Excel calculation (Ref. 3) for
detail information on the RF signal pulse.

1. General description
The NTAG I2C is the first product of NXP’s NTAG family offering both contactless and
contact interfaces (see Figure 1). In addition to the passive NFC Forum compliant
contactless interface, the IC features an I2C contact interface, which can communicate
with a microcontroller if the NTAG I2C is powered from an external power supply. An
additional externally powered SRAM mapped into the memory allows a fast data transfer
between the RF and I2C interfaces and vice versa, without the write cycle limitations of the
EEPROM memory.
The NTAG I2C product features a configurable Field Detection Pin, which provides a
trigger to an external device depending on the activities at the RF interface.
The NTAG I2C product can also supply power to external (low power) devices (e.g., a
microcontroller) via the embedded energy harvesting circuitry.

8. Functional description
8.1 Block description
NTAG I2C ICs consist of (see details below): 2016 bytes of EEPROM memory, 64 Bytes of
SRAM, a RF interface, Digital Control Unit (DCU), Power Management Unit (PMU) and an
I²C interface. Energy and data are transferred via an antenna consisting of a coil with a
few turns, which is directly connected to NTAG I2C IC. No further external components are
necessary.
• RF interface:
– modulator/demodulator
– rectifier
– clock regenerator
– Power-On Reset (POR)
– voltage regulator
• Anticollision: multiple cards may be selected and managed in sequence
• Command interpreter: processes memory access commands supported by the NTAG
I
2C
• EEPROM interface
8.2 RF interface
The RF-interface is based on the ISO/IEC 14443 Type A standard.
During operation, the NFC device generates an RF field. The RF field must always be
present (with short pauses for data communication), as it is used for both communication
and as power supply for the tag.
For both directions of data communication, there is one start bit at the beginning of each
frame. Each byte is transmitted with an odd parity bit at the end. The LSB of the byte with
the lowest address of the selected block is transmitted first. The maximum length of an
NFC device to tag frame is 163 bits (16 data bytes + 2 CRC bytes = 16×9 + 2×9 + 1 start
bit). The maximum length of a fixed size tag to NFC device frame is 307 bits (32 data
bytes + 2 CRC bytes = 32 9 + 2 9 + 1 start bit). The FAST_READ command has a
variable frame length, which depends on the start and end address parameters. The
maximum frame length supported by the NFC device must be taken into account when
issuing this command.
For a multi-byte parameter, the least significant byte is always transmitted first. For
example, when reading from the memory using the READ command, byte 0 from the
addressed block is transmitted first, followed by bytes 1 to byte 3 out of this block. The
same sequence continues for the next block and all subsequent blocks.
8.2.1 Data integrity
The following mechanisms are implemented in the contactless communication link
between the NFC device and the NTAG I²C IC to ensure very reliable data transmission:
• 16 bits CRC per blockNT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NFC Forum type 2 Tag compliant IC with I2C interface
• Parity bits for each byte
• Bit count checking
• Bit coding to distinguish between “1”, “0” and “no information”
• Channel monitoring (protocol sequence and bit stream analysis)
The commands are initiated by the NFC device and controlled by the Digital Control Unit
of the NTAG I2C IC. The command response depends on the state of the IC, and for
memory operations, also on the access conditions valid for the corresponding page.
8.2.2 RF communication principle
The overall RF communication principle is summarized in Figure 4.
8.2.2.1 IDLE state
After a power-on reset (POR), the NTAG I2C switches to the IDLE state. It only exits this
state when a REQA or a WUPA command is received from the NFC device. Any other
data received while in this state is interpreted as an error, and the NTAG I2C remains in
the IDLE state.

NXP Semiconductors NT3H1101/NT3H1201
NFC Forum type 2 Tag compliant IC with I2C interface
After a correctly executed HLTA command e.g., out of the ACTIVE state, the default
waiting state changes from the IDLE state to the HALT state. This state can then only be
exited with a WUPA command.
8.2.2.2 READY 1 state
In the READY 1 state, the NFC device resolves the first part of the UID (3 bytes) using the
ANTICOLLISION or SELECT commands in cascade level 1. This state is correctly exited
after execution of the following command:
• SELECT command from cascade level 1: the NFC device switches the NTAG I2C into
READY2 state where the second part of the UID is resolved.
8.2.2.3 READY 2 state
In the READY 2 state, the NTAG I2C supports the NFC device in resolving the second part
of its UID (4 bytes) with the cascade level 2 ANTICOLLISION command. This state is
usually exited using the cascade level 2 SELECT command.
Remark: The response of the NTAG I2C to the cascade level 2 SELECT command is the
Select AcKnowledge (SAK) byte. In accordance with ISO/IEC 14443, this byte indicates if
the anticollision cascade procedure has finished. NTAG I2C is now uniquely selected and
only this device will communicate with the NFC device even when other contactless
devices are present in the NFC device field.
8.2.2.4 ACTIVE state
All memory operations are operated in the ACTIVE state.
The ACTIVE state is exited with the HLTA command and upon reception, the NTAG I2C
transits to the HALT state. Any other data received when the device is in this state is
interpreted as an error. Depending on its previous state, the NTAG I2C returns to either
the IDLE state or HALT state.
8.2.2.5 HALT state
HALT and IDLE states constitute the two wait states implemented in the NTAG I2C. An
already processed NTAG I2C can be set into the HALT state using the HLTA command. In
the anticollision phase, this state helps the NFC device distinguish between processed
tags and tags yet to be selected. The NTAG I2C can only exit this state upon execution of
the WUPA command. Any other data received when the device is in this state is
interpreted as an error, and NTAG I2C state remains unchanged.
8.3 Memory organization
The memory map is detailed in Figure 5 (1k memory) and Figure 6 (2k memory) from the
RF interface and in Figure 7 (1k memory) and Figure 8 (2k memory) from the I2C
interface. The SRAM memory is not mapped from the RF interface, because in the default
settings of the NTAG I2C the Pass-through mode is not enabled. Please refer to
Section 11 for examples of memory map from the RF interface with SRAM mapping.
The structure of manufacturing data, static lock bytes, capability container and user
memory pages (except of the user memory length) are compatible with other NTAG
products.NT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

8.3.3 EEPROM
The EEPROM is a non volatile memory that stores the 7 byte UID, the memory lock
conditions, IC configuration information and the 1904 bytes User Data (888 byte User
Data in case of the NTAG I2C 1k version).
8.3.4 SRAM
For frequently changing data, a volatile memory of 64 bytes with unlimited endurance is
built in. The 64 bytes are mapped in a similar way as is done in the EEPROM, i.e., 64
bytes are seen as 16 pages of 4 bytes.
Remark: *The Byte 0 of Block 0 is always read as 04h. Writing to this byte modifies the I²C

NXP Semiconductors NT3H1101/NT3H1201
NFC Forum type 2 Tag compliant IC with I2C interface
The SRAM is only available if the tag is powered via the VCC pin.
The SRAM is located at the end of the memory space and it is always directly accessible
by the I2C host (addresses F8h to FBh). An RF reader cannot access the SRAM memory
in normal mode (i.e., outside the Pass-through mode). The SRAM is only accessible by
the RF reader if the SRAM is mirrored onto the EEPROM memory space.
With Memory Mirror enabled (SRAM_MIRROR_ON_OFF=1 - see Section 11.2), the
SRAM can be mirrored in the User Memory (page 1 to page 119 - see Section 11.2) for
access from the RF side.
The Memory mirror must be enabled once both interfaces are ON as this feature is
disabled after each POR.
The register SRAM_MIRROR_BLOCK (see Table 10) indicates the address of the first
page of the SRAM buffer. In the case where the SRAM mirror is enabled and the READ
command is addressing blocks where the SRAM mirror is located, the SRAM mirror byte
values will be returned instead of the EEPROM byte values. Similarly, if the tag is not VCC
powered, the SRAM mirror is disabled and reading out the bytes related to the SRAM
mirror position would return the values from the EEPROM.
In the Pass-through mode (PTHRU_ON_OFF=1 - see Section 8.3.11), the SRAM is
mirrored to the fixed address 240 -255 for RF access (see Section 11) in the first memory
sector for NTAG I2C 1k and in the second memory sector for NTAG I2C 2k.
8.3.5 UID/serial number
The unique 7-byte serial number (UID) is programmed into the first 7 bytes of memory
covering page addresses 00h and 01h - see Figure 9. These bytes are programmed and
write protected in the production test.
SN0 holds the Manufacturer ID for NXP Semiconductors (04h) in accordance with
ISO/IEC 14443-3.
8.3.6 Static lock bytes
The bits of byte 2 and byte 3 of page 02h (via RF) or byte 10 and 11 address 0h (via I2C)
represent the field programmable, read-only locking mechanism (see Figure 10). Each
page from 03h (CC) to 0Fh can be individually locked by setting the corresponding locking
bit Lx to logic 1 to prevent further write access. After locking, the corresponding page
becomes read-only memory.

NXP Semiconductors NT3H1101/NT3H1201
NFC Forum type 2 Tag compliant IC with I2C interface
The three least significant bits of lock byte 0 are the block-locking bits. Bit 2 controls
pages 0Ah to 0Fh (via RF), bit 1 controls pages 04h to 09h (via RF) and bit 0 controls
page 03h (CC). Once the block-locking bits are set, the locking configuration for the
corresponding memory area is frozen.
For example, if BL15-10 is set to logic 1, then bits L15 to L10 (lock byte 1, bit[7:2]) can no
longer be changed. The static locking and block-locking bits are set by the bytes 2 and 3
of the WRITE command to page 02h. The contents of the lock bytes are bit-wise OR’ed
and the result then becomes the new content of the lock bytes.
This process is irreversible from RF perspective. If a bit is set to logic 1, it cannot be
changed back to logic 0. From I²C perspective, the bits can be reset to “0”.
The contents of bytes 0 and 1 of page 02h are unaffected by the corresponding data bytes
of the WRITE.
The default value of the static lock bytes is 00 00h.
8.3.7 Dynamic Lock Bytes
To lock the pages of NTAG I2C starting at page address 0Fh and onwards, the dynamic
lock bytes are used. The dynamic lock bytes are located at page E2h sector 0h (NTAG I2C
1k) or address E0h sector 1 (NTAG I2C 2k). The three lock bytes cover the memory area
of 830 data bytes (NTAG I2C 1k) or 1846 data bytes (NTAG I2C 2k). The granularity is 16
pages for NTAG I2C 1k and 32 pages for NTAG I2C 2k compared to a single page for the
first 48 bytes (NTAG I2C 1k) or the first 64 bytes (NTAG I2C 2k) as shown in Figure 11 and
Figure 12.
Remark: Set all bits marked with RFUI to 0 when writing to the dynamic lock bytes.

The default value of the dynamic lock bytes is 00 00 00h. The value of Byte 3 is always
00h when read.
Reading the 3 bytes for the dynamic lock bytes and the Byte 3 (00h) from RF interface
(address E2h sector 0 (NTAG I2C 1k) or E0h sector 1 (NTAG I2C 2k) or from I2C (address
38h (NTAG I2C 1k) or 78h (NTAG I2C 2k)) will also return a fixed value for the next 12
bytes of 00h.
Like for the static lock bytes, this process of modifying the dynamic lock bytes is
irreversible from RF perspective. If a bit is set to logic 1, it cannot be changed back to
logic 0. From I²C perspective, the bits can be reset to “0”.
8.3.8 Capability Container (CC bytes)
The Capability Container CC (page 3) is programmed during the IC production according
to the NFC Forum Type 2 Tag specification (see Ref. 1). These bytes may be bit-wise
modified by a WRITE command from the I²C or RF interface. See examples for NTAG I2C
1k version in Figure 13 and for NTAG I2C 2k version in Figure 14.
The default values of the CC bytes at delivery are defined in Section 8.3.10.

8.3.10 Memory content at delivery
The capability container in page 03h and the page 04h and 05h of NTAG I2C is
pre-programmed to the initialized state according to the NFC Forum Type 2 Tag
specification (see Ref. 1) as defined in Table 4 (NTAG I2C 1k version) and Table 5 (NTAG
I
2C 2k version). This content is READ only from the RF side and READ&WRITE from the
I²C side.
The User memory contains an empty NDEF TLV.
Remark: The default content of the data pages from page 05h onwards is not defined at
delivery.
8.3.11 NTAG I2C configuration and session registers
NTAG I2C functionalities can be configured and read in two separate locations depending
if the configurations shall be effective within the communication session (session
registers) or by default after Power On Reset (POR) (configuration bits).
The configuration registers of pages E8h to E9h (sector 0 or 1 depending if it is for NTAG
I²C 1k or 2k) via the RF interface or block 3Ah or 7Ah (depending if it is for NTAG I²C 1k or
2k) via the I2C interface, see Figure 5, Figure 6, Figure 7 and Figure 8, are used to
configure the default functionalities of the NTAG I2C - see Table 6. Those bits values are
stored in the EEPROM and represent the default settings to be effective after POR. Their
values can be read & written by both interfaces when applicable and when not locked by
the register lock bits (see REG_LOCK in Table 9).

The session registers Pages F8h to F9h (sector 3) via the RF interface or block FEh via
I
2C, see Table 8, are used to configure or monitor the values of the current communication
session- see Figure 6 and Figure 8. Those bits can only be read via the RF interface but
both read and written via the I2C interface.
Both the session and the configuration bits have the same register except the
REG_LOCK bits, which are only available in the configuration bits and the NS_REG bits
which are only available in the session registers. After POR, the configuration bits are
loaded into the session registers. During the communication session, the values can be
changed, but the related effect will only be visible within the communication session for
the session registers or after POR for the configuration bits. After POR, the registers
values will be again brought back to the default configuration values.
All registers and configuration default values, access and descriptions are described in
Table 9 and Table 10.
Reading and writing the session registers via I²C can only be done via the READ &
WRITE registers operation - see Section 9.8.

8.5 Watchdog timer
In order to allow the I²C interface to perform all necessary commands (READ, WRITE...),
the memory access remains locked to the I²C interface til the register I2C_LOCKED is
cleared by the host - see Table 10.
In order however to avoid that the memory stays 'locked' to the I²C for a long period of
time, it is possible to program a watchdog timer to unlock the I2C host from the tag, so that
the RF reader can access the tag after a period of time of inactivity. The host itself will not
be notified of this event directly, but the NS_REG register is updated accordingly (the
register bit I2C_LOCKED will be cleared - see Table 10).
The default value is set to 20 ms (848h), but the watch dog timer can be freely set from
0001h (9.43 s) up to FFFFh (617.995 s). The timer starts ticking when the
communication between the NTAG I2C and the I2C interface starts. In case the

communication with the I2C is still going on after the watchdog timer expires, the
communication will continue until the communication has completed. Then the status
register I2C_LOCKED will be immediately cleared.
In the case where the communication with the I2C interface has completed before the end
of the timer and the status register I2C_LOCKED was not cleared by the host, it will be
cleared at the end of the watchdog timer.
The watchdog timer is only effective if the VCC pin is powered and will be reset and
stopped if the NTAG I2C is not VCC powered or if the register status I2C_LOCKED is set
to 0 and RF_LOCKED is set to 1.
8.6 Energy harvesting
The NTAG I2C provides the capability to supply external low power devices with energy
generated from the RF field of a NFC device.
The voltage and current from the energy harvesting depend on various parameters, such
as the strength of the RF field, the tag antenna size, or the distance from the NFC device.
At room temperature, NTAG I2C could provide typically 5 mA at 2 V on the VOUT pin with
an NFC Phone.
Operating NTAG I2C in energy harvesting mode requires a number of precautions:
• A significant buffer capacitor in the range of typically 10nF up to 100 nF maximum
shall be connected between VOUT and GND close to the terminals.
• If NTAG I2C also powers the I2C bus, then VCC must be connected to VOUT, and
pull-up resistors on the SCL and SDA pins must be sized to control SCL and SDA sink
current when those lines are pulled low by NTAG I2C or the I2C host
• If NTAG I2C also powers the Field Detect bus, then the pull-up resistor on the Field
Detect line must be sized to control the sink current into the Field Detect pin when
NTAG I2C pulls it low
• The NFC reader device communicating with NTAG I2C shall apply polling cycles
including an RF Field Off condition of at least 5.1 ms as defined in NFC Forum Activity
specification (see Ref. 4, chapter 6).
Note that increasing the output current on the Vout decreases the RF communication
range.NT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

9. I²C commands
For details about I2C interface refer to Ref. 3.
The NTAG I2C supports the I2C protocol. This protocol is summarized in Figure 18. Any
device that sends data onto the bus is defined as a transmitter, and any device that reads
the data from the bus is defined as a receiver. The device that controls the data transfer is
known as the “bus master”, and the other as the “slave” device. A data transfer can only
be initiated by the bus master, which will also provide the serial clock for synchronization.
The NTAG I2C is always a slave in all communications.
9.1 Start condition
Start is identified by a falling edge of Serial Data (SDA), while Serial Clock (SCL) is stable
in the high state. A Start condition must precede any data transfer command. The NTAG
I
2C continuously monitors SDA (except during a Write cycle) and SCL for a Start
condition, and will not respond unless one is given.
9.2 Stop condition
Stop is identified by a rising edge of SDA while SCL is stable and driven high. A Stop
condition terminates communication between the NTAG I2C and the bus master. A Stop
condition at the end of a Write command triggers the internal Write cycle.

9.3 Soft reset feature
In the case where the I2C interface is constantly powered on, NTAG I2C can trigger a reset
of the I2C interface via its soft reset feature- see Table 9.
When this feature is enabled, if the microcontroller does not issue a stop condition
between two start conditions, this situation will trigger a reset of the I2C interface and
hence may hamper the communication via the I2C interface.
9.4 Acknowledge bit (ACK)
The acknowledge bit is used to indicate a successful byte transfer. The bus transmitter,
whether it is the bus master or slave device, releases Serial Data (SDA) after sending
eight bits of data. During the 9th clock pulse period, the receiver pulls Serial Data (SDA)
low to acknowledge the receipt of the eight data bits.
9.5 Data input
During data input, the NTAG I2C samples SDA on the rising edge of SCL. For correct
device operation, SDA must be stable during the rising edge of SCL, and the SDA signal
must change only when SCL is driven low.
9.6 Addressing
To start communication between a bus master and the NTAG I2C slave device, the bus
master must initiate a Start condition. Following this initiation, the bus master sends the
device address. The NTAG I2C address from I2C consists of a 7-bit device identifier (see
Table 11 for default value).
The 8th bit is the Read/Write bit (RW). This bit is set to 1 for Read and 0 for Write
operations.
If a match occurs on the device address, the NTAG I2C gives an acknowledgment on SDA
during the 9th bit time. If the NTAG I2C does not match the device select code, it deselects
itself from the bus and clear the register I2C_LOCKED (see Table 8).
[1] Initial values - can be changed.
The I2C address of the NTAG I2C (byte 0 - block 0h) can only be modified by the I2C
interface. Both interfaces have no READ access to this address and a READ command
from the RF or I²C interface to this byte will only return 04h (manufacturer ID for NXP
Semiconductors - see Figure 9).

The READ and WRITE operation handle always 16 bytes to be read or written (one block
- see Figure 8)
For the READ operation (see Figure 19), following a Start condition, the bus master/host
sends the NTAG I2C slave address code (SA - 7 bits) with the Read/Write bit (RW) reset to
0. The NTAG I2C acknowledges this (A), and waits for one address byte (MEMA), which
should correspond to the address of the block of memory (SRAM or EEPROM) that is
intended to be read. The NTAG I2C responds to a valid address byte with an acknowledge
(A). A Stop condition can be then issued. Then the host again issues a start condition
followed by the NTAG I2C slave address with the Read/Write bit set to “1”. The NTAG I2C
acknowledges this (A) and sends the first byte of data read (D0).The bus master/host
acknowledges it (A) and the NTAG I2C will subsequently transmit the following 15 bytes of
memory read with an acknowledge from the host after every byte. After the last byte of
memory data has been transmitted by the NTAG I2C, the bus master/host will
acknowledge it and issue a Stop condition.
For the WRITE operation (see Figure 19), following a Start condition, the bus master/host
sends the NTAG I2C slave address code (SA - 7 bits) with the Read/Write bit (RW) reset to
0. The NTAG I2C acknowledges this (A), and waits for one address byte (MEMA), which
should correspond to the address of the block of memory (SRAM or EEPROM) that is
intended to be written. The NTAG I2C responds to a valid address byte with an
acknowledge (A) and, in the case of a WRITE operation, the bus master/host starts
transmitting each 16 bytes (D0...D15) that shall be written at the specified address with an
acknowledge of the NTAG I²C after each byte (A). After the last byte acknowledge from
the NTAG I²C, the bus master/host issues a Stop condition.
The memory address accessible via the READ and WRITE operations can only
correspond to the EEPROM or SRAM (respectively 00h to 3Ah or F8h to FBh for NTAG
I²C 1k and 00h to 7Ah or F8h to FBh for NTAG I²C 2k).xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxx x x x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xx xx xxxxx

For the READ register operation, following a Start condition the bus master/host sends the
NTAG I²C slave address code (SA - 7 bits) with the Read/Write bit (RW) reset to 0. The
NTAG I2C acknowledges this (A), and waits for one address byte (MEMA) which
corresponds to the address of the block of memory with the session register bytes (FEh).
The NTAG I2C responds to the address byte with an acknowledge (A). Then the bus
master/host issues a register address (REGA), which corresponds to the address of the
targeted byte inside the block FEh (00h, 01h...to 07h) and then waits for the Stop
condition.
Then the bus master/host again issues a start condition followed by the NTAG I²C slave
address with the Read/Write bit set to “1”. The NTAG I²C acknowledges this (A), and
sends the selected byte of session register data (REGDAT) within the block FEh. The bus
master/host will acknowledge it and issue a Stop condition.
For the WRITE register operation, following a Start condition, the bus master/host sends
the NTAG I²C slave address code (SA - 7 bits) with the Read/Write bit (RW) reset to 0.
The NTAG I2C acknowledges this (A), and waits for one address byte (MEMA), which
corresponds to the address of the block of memory within the session register bytes
(FEh). After the NTAG I2C acknowledge (A), the bus master/host issues a MASK byte that
defines exactly which bits shall be modified by a “1” bit value at the corresponding bit
position. Following the NTAG I²C acknowledge (A), the new register data (one byte -
REGDAT) to be written is transmitted by the bus master/host. The NTAG I²C
acknowledges it (A), and the bus master/host issues a stop condition.NT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

10. RF Command
NTAG activation follows the ISO/IEC 14443 Type A specification. After NTAG I2C has
been selected, it can either be deactivated using the ISO/IEC 14443 HALT command, or
NTAG commands (e.g., READ or WRITE) can be performed. For more details about the
card activation refer to Ref. 2.
10.1 NTAG I2C command overview
All available commands for NTAG I2C are shown in Table 12.
[1] Unless otherwise specified, all commands use the coding and framing as described in Ref. 1.
10.2 Timing
The command and response timing shown in this document are not to scale and values
are rounded to 1 s.
All given command and response times refer to the data frames, including start of
communication and end of communication. They do not include the encoding (like the
Miller pulses). An NFC device data frame contains the start of communication (1
“start bit”) and the end of communication (one logic 0 + 1 bit length of unmodulated
carrier). An NFC tag data frame contains the start of communication (1 “start bit”) and the
end of communication (1 bit length of no subcarrier).
The minimum command response time is specified according to Ref. 1 as an integer n,
which specifies the NFC device to NFC tag frame delay time. The frame delay time from
NFC tag to NFC device is at least 87 s. The maximum command response time is
specified as a time-out value. Depending on the command, the TACK value specified for
command responses defines the NFC device to NFC tag frame delay time. It does it for
either the 4-bit ACK value specified or for a data frame.
All timing can be measured according to the ISO/IEC 14443-3 frame specification as
shown for the Frame Delay Time in Figure 21. For more details refer to Ref. 2.

Remark: The ATQA coding in bits 7 and 8 indicate the UID size according to
ISO/IEC 14443 independent from the settings of the UID usage.
Remark: The bit numbering in the ISO/IEC 14443 specification starts with LSB = bit 1 and
not with
LSB = bit 0. So 1 byte counts bit 1 to bit 8 instead of bit 0 to 7.

The user memory for NTAG I²C 1k is 888 bytes. This memory size is between 512 bytes
and 1024 bytes. Therefore, the most significant 7 bits of the value 13h, are interpreted as
9d, and the least significant bit is 1b.
The user memory for NTAG I²C 2k is 1904 bytes. This memory size is between 1024
bytes and 2048 bytes. Therefore, the most significant 7 bits of the value 15h, are
interpreted as 10d, and the least significant bit is 1b.
10.6 READ
The READ command requires a start page address, and returns the 16 bytes of four
NTAG I2C pages. For example, if address (Addr) is 03h then pages 03h, 04h, 05h, 06h are
returned. Special conditions apply if the READ command address is near the end of the
accessible memory area. For details on those cases and the command structure refer to
Figure 23 and Table 19.

[1] Refer to Section 10.2 “Timing”.
In the initial state of NTAG I2C, all memory pages are allowed as Addr parameter to the
READ command:
• Page address from 00h to E2h and E8h for NTAG I²C 1k
• Page address from 00h to FFh (sector 0h), from page 00h to E0h and E8h (sector 1h)
for NTAG I²C 2k
• SRAM buffer when Passthrough is ON
Addressing a start memory page beyond the limits above results in a NAK response from
NTAG I2C.
In case a READ command addressing start with a valid memory area but extends over an
invalid memory area, the content of the invalid memory area will be reported as 00h.
10.7 FAST_READ
The FAST_READ command requires a start page address and an end page address and
returns all n*4 bytes of the addressed pages. For example, if the start address is 03h and
the end address is 07h, then pages 03h, 04h, 05h, 06h and 07h are returned.
For details on those cases and the command structure, refer to Figure 24 and Table 21.

The WRITE command requires a block address, and writes 4 bytes of data into the
addressed NTAG I2C page. The WRITE command is shown in Figure 25 and Table 23.
Table 24 shows the required timing.
[1] Refer to Section 10.2 “Timing”.
In the initial state of NTAG I2C, the following memory pages are valid Addr parameters to
the WRITE command:
• Page address from 02h to E2h, E8h and E9h (sector 0h) for NTAG I²C 1k
• Page address from 02h to FFh (sector 0h), from 00h to E2h, E8h and E9h (sector 1h)
for NTAG I²C 2k
• SRAM buffer address in Passthrough mode
Addressing a memory page beyond the limits above results in a NAK response from
NTAG I2C.
Pages that are locked against writing cannot be reprogrammed using any write command.
The locking mechanisms include static and dynamic lock bits, as well as the locking of the
configuration pages.

10.9 SECTOR SELECT
The SECTOR SELECT command consists of two commands packet: the first one is the
SECTOR SELECT command (C2h), FFh and CRC. Upon an ACK answer from the Tag,
the second command packet needs to be issued with the related sector address to be
accessed and 3 bytes RFU.
To successfully access to the requested memory sector, the tag shall issue a passive
ACK, which is sending NO REPLY for more than 1ms after the CRC of the second
command set.

11. Communication and arbitration between RF and I²C interface
If both interfaces are powered by their corresponding source, only one interface shall
have access according to the "first-come, first-serve" principle.
In NS_REG, the two status bits I2C_LOCKED and RF_LOCKED reflect the status of the
NTAG I²C memory access and indicate which interface is locking the memory access. At
power on, both bits are 0, setting the arbitration in idle mode.
In the case arbiter locks to the I²C interface, an RF reader still can access the session
registers. If the ISO state machine is in 'active' state, only the SECTOR SELECT
command is allowed. But any other command requiring EEPROM access like READ or
WRITE is handled as an illegal command and replied to with a special NAK value.
In the case where the memory access is locked to the RF interface, the I²C host still can
access the NFC register, by issuing a 'Register READ/WRITE' command. All other read or
write commands will be replied to with a NACK to the I²C host.
11.1 Non Pass-through Mode
PTHRU_ON_OFF = 0 (see Table 10) indicates non-Pass-through mode.
11.1.1 I²C interface access
If the tag is in the IDLE or HALT state (RF state after POR or HALT-command) and the
correct I²C slave address of NTAG I²C is specified following the START condition, bit
I2C_LOCKED will be automatically set to “1b”. If I2C_LOCKED=,1 the I²C interface has
access to the tag memory and the tag will respond with a NACK to any memory
READ/WRITE command on the RF interface other than reading the register bytes
command during this time.
I2C_LOCKED must be either reset to 0 at the end of the I²C sequence or wait until the end
of the watch dog timer.
11.1.2 RF interface access
The arbitration will allow the RF interface to read and write accesses to EEPROM only
when I2C_LOCKED is not set to “1b”.
RF_LOCKED is automatically set to “1b” if the tag receives a valid command (EEPROM
Access Commands) on the RF interface. If RF_LOCKED=1, the tag is locked to the RF
interface and will not respond to any command from the I²C interface other than READ
register command (see Table 10).
RF_LOCKED is automatically set to 0 in one of the following conditions
• At POR or if the RF field is switched off
• If the tag is set to the HALT state with a HALT command on the RF interface
• If the memory access command is finished on the RF interface
When the RF interface has read the last page of the NDEF message specified in
LAST_NDEF_BLOCK (see Table 9 and Table 10) the bit NDEF_DATA_READ - in the
register NS_REG see Table 10 - is set to “1b” and indicates to the I²C interface that, for
example, new NDEF data can be written. NT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

11.2 SRAM buffer mapping with Memory Mirror enabled
With SRAM_MIRROR_ON_OFF= 1, the SRAM buffer mirroring is enabled. This mode
cannot be combined with the pass through mode (see Section 11.3).
With the Memory Mirror enabled, the SRAM is now mapped into the User Memory from
the RF interface perspective using the SRAM mirror lower page address specified in
SRAM_MIRROR_BLOCK byte (Table 9 and Table 10). See Figure 27 (NTAG I²C 1k) and
Figure 28(NTAG I²C 2k) for an illustration of this SRAM memory mapping when
SRAM_MIRROR_BLOCK is set to 1h. The SRAM buffer will be then available in 2
locations: inside the User memory and at the end of the first or second memory sector
(respectively NTAG I²C 1k or NTAG I²C 2k).
The tag must be VCC powered to make this mode work, because without VCC, the SRAM
will not be accessible via RF powered only.
When mapping the SRAM buffer to the User Memory, the User shall be aware that all data
written into the SRAM part of the User memory will be lost once the NTAG I²C is no longer
powered from the I²C side (as SRAM is a volatile memory).NT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

11.3 Pass-through mode
PTHRU_ON_OFF = 1 (see Table 10) enables and indicates Pass-through mode.
To handle large amount of data transfer from one interface to the other, NTAG I²C offers
the Pass-through mode where data is transferred via a 64 byte SRAM buffer. This buffer
offers fast write access and unlimited WRITE endurance as well as an easy handshake
mechanism between the 2 interfaces.

NFC Forum type 2 Tag compliant IC with I2C interface
This buffer is mapped directly at the end of the sector 0h (NTAG I²C 1k) or sector 1h
(NTAG I²C 2k) of the memory (from the RF interface perspective).
In both cases, the principle of access to the SRAM buffer via the RF and I²C interface is
exactly the same (see Section 11.3.2 and Section 11.3.3).
The data flow direction must be set with the PTHRU_DIR bit (see Table 10) within the
current communication session with the session registers (in this case, it can only be set
via the I²C interfaces) or for the configuration bits after POR (in this case both RF and I²C
interface can set it). This pass through direction settings avoids locking the memory
access during the data transfer from one interface to the SRAM buffer.
The pass-through mode can only be enabled when both interfaces are ON and only via
the I²C interface via the bit PTHRU_ON_OFF located in the session registers NC_REG
(see Section 8.3.11). In case one interface powers off, the pass-through mode is disabled
automatically.
11.3.1 SRAM buffer mapping
In Pass-through mode, the SRAM is mirrored to pages F0h to FFh sector 0h for the NTAG
I²C 1k - see Figure 29 - or sector 1h for the NTAG I²C 2k - see Figure 30 - outside the User
memory.
The last page/block of the SRAM buffer (page 16) is used as the terminator page. Once
the terminator page/block in the respective interfaces is read/written, the control would be
transferred to other interface (RF/I²C) - see Section 11.3.2 and Section 11.3.3 for more
details.
Accordingly, the application can align on the Reader & Host side to transfer 16/32/48/64
bytes of data in one pass through step by only using the last blocks/page of the SRAM
buffer.
When using FAST_READ to read the SRAM buffer from RF, the EndAddress input of the
FAST_READ command has to be always set to FFh.NT3H1101/NT3H1201 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors NT3H1101/NT3H1201
NFC Forum type 2 Tag compliant IC with I2C interface
To signal to the host that data is ready to be read following mechanisms are in place:
• The host polls/reads bit SRAM_I2C_READY from NS_REG (see Table 10) to know if
data is ready in SRAM
• A trigger on the "FD" pin indicates to the host that data is ready to be read from
SRAM. This feature can be enabled by programming bits 5:2 (FD_OFF, FD_ON) of
the NC_REG appropriately (see Table 9)
This is illustrated in the Figure 31.
If the tag is addressed with the correct I²C slave address, the I2C_LOCKED bit is
automatically set to 1 (according to the interface arbitration). After a READ from the
terminator page of the SRAM, bit SRAM_I2C_READY and bit I2C_LOCKED are
automatically reset to 0, and the tag returns to the arbitration idle mode where, for
example, further data from the RF interface can be transferred.xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxx x x x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xx xx xxxxx

11.3.3 I²C to RF Data transfer
If the I²C interface is enabled (I2C_LOCKED is 1) and data is written to the terminator
page of the SRAM via the I²C interface, at the end of the WRITE command, bit
SRAM_RF_READY is set to 1 and bit I2C_LOCKED is automatically reset to 0 to set the
tag in the arbitration idle state.
The RF_LOCKED bit is then automatically set to 1 (according to the interface arbitration).
After a READ or FAST_READ command involving the terminator block/page of the
SRAM, bit SRAM_RF_READY and bit RF_LOCKED are automatically reset to 0 allowing
the I²C interface to further write data into the SRAM buffer.
To signal to the host that further data is ready to be written, the following mechanisms are
in place:
• The RF interface polls/reads the bit SRAM_RF_READY from NS_REG (see Table 10)
to know if new data has been written by the I²C interface in the SRAM
• A trigger on the "FD" pin indicates to the host that data has been read from SRAM by
the RF interface. This feature can be enabled by programming bits 5:2 (FD_OFF,
FD_ON) of the NC_REG appropriately (see Table 9)
The above mechanism is illustrated in the Figure 32.xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxx x x x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xx xx xxxxx

NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
Two/one 16 kB SRAM blocks with separate access paths for higher throughput.
These SRAM blocks may be used for Ethernet, USB, and DMA memory, as well as
for general purpose CPU instruction and data storage.
Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer
matrix that can be used with SSP, I2S-bus, UART, Analog-to-Digital and
Digital-to-Analog converter peripherals, timer match signals, and for
memory-to-memory transfers.
Multilayer AHB matrix interconnect provides a separate bus for each AHB master.
AHB masters include the CPU, General Purpose DMA controller, Ethernet MAC, and
the USB interface. This interconnect provides communication with no arbitration
delays.
Split APB bus allows high throughput with few stalls between the CPU and DMA.
Serial interfaces:
Ethernet MAC with RMII interface and dedicated DMA controller. (Not available on
all parts, see Table 2.)
USB 2.0 full-speed device/Host/OTG controller with dedicated DMA controller and
on-chip PHY for device, Host, and OTG functions. (Not available on all parts, see
Table 2.)
Four UARTs with fractional baud rate generation, internal FIFO, and DMA support.
One UART has modem control I/O and RS-485/EIA-485 support, and one UART
has IrDA support.
CAN 2.0B controller with two channels. (Not available on all parts, see Table 2.)
SPI controller with synchronous, serial, full duplex communication and
programmable data length.
Two SSP controllers with FIFO and multi-protocol capabilities. The SSP interfaces
can be used with the GPDMA controller.

I
2C specification and Fast mode plus with data rates of 1 Mbit/s, two with standard
port pins. Enhancements include multiple address recognition and monitor mode.
I
2S (Inter-IC Sound) interface for digital audio input or output, with fractional rate
control. The I2S-bus interface can be used with the GPDMA. The I2S-bus interface
supports 3-wire and 4-wire data transmit and receive as well as master clock
input/output. (Not available on all parts, see Table 2.)
Other peripherals:
70 (100 pin package) General Purpose I/O (GPIO) pins with configurable
pull-up/down resistors. All GPIOs support a new, configurable open-drain operating
mode. The GPIO block is accessed through the AHB multilayer bus for fast access
and located in memory such that it supports Cortex-M3 bit banding and use by the
General Purpose DMA Controller.

NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
8. Functional description
8.1 Architectural overview
Remark: In the following, the notation LPC17xx refers to all parts:
LPC1769/68/67/66/65/64/63.
The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and
the D-code bus (see Figure 1). The I-code and D-code core buses are faster than the
system bus and are used similarly to TCM interfaces: one bus dedicated for instruction
fetch (I-code) and one bus for data access (D-code). The use of two core buses allows for
simultaneous operations if concurrent operations target different devices.
The LPC17xx use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and
other bus masters to peripherals in a flexible manner that optimizes performance by
allowing peripherals that are on different slaves ports of the matrix to be accessed
simultaneously by different bus masters.
8.2 ARM Cortex-M3 processor
The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM Cortex-M3 offers many new
features, including a Thumb-2 instruction set, low interrupt latency, hardware divide,
interruptible/continuable multiple load and store instructions, automatic state save and
restore for interrupts, tightly integrated interrupt controller with wake-up interrupt
controller, and multiple core buses capable of simultaneous accesses.
Pipeline techniques are employed so that all parts of the processing and memory systems
can operate continuously. Typically, while one instruction is being executed, its successor
is being decoded, and a third instruction is being fetched from memory.
The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical
Reference Manual that can be found on official ARM website.
8.3 On-chip flash program memory
The LPC17xx contain up to 512 kB of on-chip flash memory. A new two-port flash
accelerator maximizes performance for use with the two fast AHB-Lite buses.
8.4 On-chip SRAM
The LPC17xx contain a total of 64 kB on-chip static RAM memory. This includes the main
32 kB SRAM, accessible by the CPU and DMA controller on a higher-speed bus, and two
additional 16 kB each SRAM blocks situated on a separate slave port on the AHB
multilayer matrix.
This architecture allows CPU and DMA accesses to be spread over three separate RAMs
that can be accessed simultaneously.
8.5 Memory Protection Unit (MPU)
The LPC17xx have a Memory Protection Unit (MPU) which can be used to improve the
reliability of an embedded system by protecting critical data within the user application.LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 9.5 — 24 June 2014 22 of 89
NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
The MPU allows separating processing tasks by disallowing access to each other's data,
disabling access to memory regions, allowing memory regions to be defined as read-only
and detecting unexpected memory accesses that could potentially break the system.
The MPU separates the memory into distinct regions and implements protection by
preventing disallowed accesses. The MPU supports up to 8 regions each of which can be
divided into 8 subregions. Accesses to memory locations that are not defined in the MPU
regions, or not permitted by the region setting, will cause the Memory Management Fault
exception to take place.
8.6 Memory map
The LPC17xx incorporates several distinct memory regions, shown in the following
figures. Figure 5 shows the overall map of the entire address space from the user
program viewpoint following reset. The interrupt vector area supports address remapping.
The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals.
The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.xxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxx x x x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx xx xx xxxxx

NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
8.7 Nested Vectored Interrupt Controller (NVIC)
The NVIC is an integral part of the Cortex-M3. The tight coupling to the CPU allows for low
interrupt latency and efficient processing of late arriving interrupts.
8.7.1 Features
• Controls system exceptions and peripheral interrupts
• In the LPC17xx, the NVIC supports 33 vectored interrupts
• 32 programmable interrupt priority levels, with hardware priority level masking
• Relocatable vector table
• Non-Maskable Interrupt (NMI)
• Software interrupt generation
8.7.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags may also represent more than one interrupt
source.
Any pin on Port 0 and Port 2 (total of 42 pins) regardless of the selected function, can be
programmed to generate an interrupt on a rising edge, a falling edge, or both.
8.8 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on-chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated and prior
to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
Most pins can also be configured as open-drain outputs or to have a pull-up, pull-down, or
no resistor enabled.
8.9 General purpose DMA controller
The GPDMA is an AMBA AHB compliant peripheral allowing selected peripherals to have
DMA support.
The GPDMA enables peripheral-to-memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. The source and
destination areas can each be either a memory region or a peripheral, and can be
accessed through the AHB master. The GPDMA controller allows data transfers between
the USB and Ethernet controllers and the various on-chip SRAM areas. The supported
APB peripherals are SSP0/1, all UARTs, the I2S-bus interface, the ADC, and the DAC.
Two match signals for each timer can be used to trigger DMA transfers.
Remark: The Ethernet controller is available on parts LPC1769/68/67/66/64. The USB
controller is available on parts LPC1769/68/66/65/64. The I2S-bus interface is available on

32-bit ARM Cortex-M3 microcontroller
8.9.1 Features
• Eight DMA channels. Each channel can support an unidirectional transfer.
• 16 DMA request lines.
• Single DMA and burst DMA request signals. Each peripheral connected to the DMA
Controller can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the DMA Controller.
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers are supported.
• Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
• Hardware DMA channel priority.
• AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
• One AHB bus master for transferring data. The interface transfers data when a DMA
request goes active.

mode on reset.
• An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
• Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
8.10 Fast general purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back as well as the current state of the port pins.

The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial Clock line
(SCL) and a Serial DAta line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be
controlled by more than one bus master connected to it.
8.19.1 Features
• I
2C0 is a standard I2C compliant bus interface with open-drain pins. I2C0 also

8.20 I2S-bus serial I/O controllers
Remark: The I2S-bus interface is available on parts LPC1769/68/67/66/65/63. See
Table 2.
The I2S-bus provides a standard communication interface for digital audio applications.
The I
2S-bus specification defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. The basic I2S-bus connection has one master, which is
always the master, and one slave. The I2S-bus interface provides a separate transmit and
receive channel, each of which can operate as either a master or a slave.
8.20.1 Features
• The interface has separate input/output channels each of which can operate in master
or slave mode.
• Capable of handling 8-bit, 16-bit, and 32-bit word sizes.
• Mono and stereo audio data supported.
• The sampling frequency can range from 16 kHz to 96 kHz (16, 22.05, 32, 44.1, 48,
96) kHz.
• Support for an audio master clock.
• Configurable word select period in master mode (separately for I2S-bus input and
output).
• Two 8-word FIFO data buffers are provided, one for transmit and one for receive.
• Generates interrupt requests when buffer levels cross a programmable boundary.
• Two DMA requests, controlled by programmable buffer levels. These are connected
to the GPDMA block.
• Controls include reset, stop and mute options separately for I2S-bus input and I2S-bus
output.
8.21 General purpose 32-bit timers/external event counters
The LPC17xx include four 32-bit timer/counters. The timer/counter is designed to count
cycles of the system derived clock or an externally-supplied clock. It can optionally
generate interrupts, generate timed DMA requests, or perform other actions at specified
timer values, based on four match registers. Each timer/counter also includes two capture
inputs to trap the timer value when an input signal transitions, optionally generating an
interrupt.
8.21.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• Counter or timer operation.
• Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event may also generate an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
• Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
• Up to two match registers can be used to generate timed DMA requests.
8.22 Pulse width modulator
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC17xx. The Timer is designed to count
cycles of the system derived clock and optionally switch pins, generate interrupts or
perform other actions when specified timer values occur, based on seven match registers.
The PWM function is in addition to these features, and is based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires
three non-overlapping PWM outputs with individual control of all three pulse widths and
positions.
Two match registers can be used to provide a single edge controlled PWM output. One
match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon
match. The other match register controls the PWM edge position. Additional single edge
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, the PWMMR0 match register controls the PWM cycle rate. The other match
registers control the two PWM edge positions. Additional double edge controlled PWM
outputs require only two match registers each, since the repetition rate is the same for all
PWM outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
8.22.1 Features
• One PWM block with Counter or Timer operation (may use the peripheral clock or one
of the capture inputs as the clock source).
• Seven match registers allow up to 6 single edge controlled or 3 double edge
controlled PWM outputs, or a mix of both types. The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
• Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go high at the beginning of each cycle unless the
output is a constant low. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.
• Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
• May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler
if the PWM mode is not enabled.
8.23 Motor control PWM
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input is also provided that causes the
PWM to immediately release all motor drive outputs. At the same time, the motor control
PWM is highly configurable for other generalized timing, counting, capture, and compare
applications.
8.24 Quadrature Encoder Interface (QEI)
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user can track the position, direction of rotation, and
velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.
8.24.1 Features
• Tracks encoder position.
• Increments/decrements depending on direction.
• Programmable for 2 or 4 position counting.
• Velocity capture using built-in timer.
• Velocity compare function with “less than” interrupt.
• Uses 32-bit registers for position and velocity.
• Three position compare registers with interrupts.
• Index counter for revolution counting.
• Index compare register with interrupts.

32-bit ARM Cortex-M3 microcontroller
• Digital filter with programmable delays for encoder input signals.
• Can accept decoded signal inputs (clk and direction).
• Connected to APB.
8.25 Repetitive Interrupt (RI) timer
The repetitive interrupt timer provides a free-running 32-bit counter which is compared to
a selectable value, generating an interrupt when a match occurs. Any bits of the
timer/compare can be masked such that they do not contribute to the match detection.
The repetitive interrupt timer can be used to create an interrupt that repeats at
predetermined intervals.
8.25.1 Features
• 32-bit counter running from PCLK. Counter can be free-running or be reset by a
generated interrupt.
• 32-bit compare value.
• 32-bit compare mask. An interrupt is generated when the counter value equals the
compare value, after masking. This allows for combinations not possible with a simple
compare.
8.26 ARM Cortex-M3 system tick timer
The ARM Cortex-M3 includes a system tick timer (SYSTICK) that is intended to generate
a dedicated SYSTICK exception at a 10 ms interval. In the LPC17xx, this timer can be
clocked from the internal AHB clock or from a device pin.
8.27 Watchdog timer
The purpose of the watchdog is to reset the microcontroller within a reasonable amount of
time if it enters an erroneous state. When enabled, the watchdog will generate a system
reset if the user program fails to ‘feed’ (or reload) the watchdog within a predetermined
amount of time.
8.27.1 Features
• Internally resets chip if not periodically reloaded.
• Debug mode.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect/Incomplete feed sequence causes reset/interrupt if enabled.
• Flag to indicate watchdog reset.
• Programmable 32-bit timer with internal prescaler.
• Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 232 4) in
multiples of Tcy(WDCLK) 4.

conditions. It also provides the ability to run the WDT from an entirely internal source
that is not dependent on an external crystal and its associated components and wiring
for increased reliability.
• Includes lock/safe feature.
8.28 RTC and backup registers
The RTC is a set of counters for measuring time when system power is on, and optionally
when it is off. The RTC on the LPC17xx is designed to have extremely low power
consumption, i.e. less than 1 A. The RTC will typically run from the main chip power
supply, conserving battery power while the rest of the device is powered up. When
operating from a battery, the RTC will continue working down to 2.1 V. Battery power can
be provided from a standard 3 V Lithium button cell.
An ultra-low power 32 kHz oscillator will provide a 1 Hz clock to the time counting portion
of the RTC, moving most of the power consumption out of the time counting function.
The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way
that will provide less than 1 second per day error when operated at a constant voltage and
temperature. A clock output function (see Section 8.29.4) makes measuring the oscillator
rate easy and accurate.
The RTC contains a small set of backup registers (20 bytes) for holding data while the
main part of the LPC17xx is powered off.
The RTC includes an alarm function that can wake up the LPC17xx from all reduced
power modes with a time resolution of 1 s.
8.28.1 Features
• Measures the passage of time to maintain a calendar and clock.
• Ultra low power design to support battery powered systems.
• Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and
Day of Year.
• Dedicated power supply pin can be connected to a battery or to the main 3.3 V.
• Periodic interrupts can be generated from increments of any field of the time registers.
• Backup registers (20 bytes) powered by VBAT.
• RTC power supply is isolated from the rest of the chip.
8.29 Clocking and power control
8.29.1 Crystal oscillators
The LPC17xx include three independent oscillators. These are the main oscillator, the IRC
oscillator, and the RTC oscillator. Each oscillator can be used for more than one purpose
as required in a particular application. Any of the three clock sources can be chosen by
software to drive the main PLL and ultimately the CPU.
Following reset, the LPC17xx will operate from the Internal RC oscillator until switched by
software. This allows systems to operate without any external crystal and the bootloader
code to operate at a known frequency. LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

32-bit ARM Cortex-M3 microcontroller
See Figure 6 for an overview of the LPC17xx clock generation.
8.29.1.1 Internal RC oscillator
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
PLL and subsequently the CPU. The nominal IRC frequency is 4 MHz. The IRC is
trimmed to 1 % accuracy over the entire voltage and temperature range.
Upon power-up or any chip reset, the LPC17xx use the IRC as the clock source. Software
may later switch to one of the other available clock sources.
8.29.1.2 Main oscillator
The main oscillator can be used as the clock source for the CPU, with or without using the
PLL. The main oscillator also provides the clock source for the dedicated USB PLL.
The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the main
PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock
frequency is referred to as CCLK elsewhere in this document. The frequencies of
PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The
clock frequency for each peripheral can be selected individually and is referred to as
PCLK. Refer to Section 8.29.2 for additional information.
8.29.1.3 RTC oscillator
The RTC oscillator can be used as the clock source for the RTC block, the main PLL,
and/or the CPU.

NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
8.29.2 Main PLL (PLL0)
The PLL0 accepts an input clock frequency in the range of 32 kHz to 25 MHz. The input
frequency is multiplied up to a high frequency, then divided down to provide the actual
clock used by the CPU and/or the USB block.
The PLL0 input, in the range of 32 kHz to 25 MHz, may initially be divided down by a
value ‘N’, which may be in the range of 1 to 256. This input division provides a wide range
of output frequencies from the same input frequency.
Following the PLL0 input divider is the PLL0 multiplier. This can multiply the input divider
output through the use of a Current Controlled Oscillator (CCO) by a value ‘M’, in the
range of 1 through 32768. The resulting frequency must be in the range of 275 MHz to
550 MHz. The multiplier works by dividing the CCO output by the value of M, then using a
phase-frequency detector to compare the divided CCO output to the multiplier input. The
error value is used to adjust the CCO frequency.
The PLL0 is turned off and bypassed following a chip Reset and by entering Power-down
mode. PLL0 is enabled by software only. The program must configure and activate the
PLL0, wait for the PLL0 to lock, and then connect to the PLL0 as a clock source.
8.29.3 USB PLL (PLL1)
The LPC17xx contain a second, dedicated USB PLL1 to provide clocking for the USB
interface.
The PLL1 receives its clock input from the main oscillator only and provides a fixed
48 MHz clock to the USB block only. The PLL1 is disabled and powered off on reset. If the
PLL1 is left disabled, the USB clock will be supplied by the 48 MHz clock from the main
PLL0.
The PLL1 accepts an input clock frequency in the range of 10 MHz to 25 MHz only. The
input frequency is multiplied up the range of 48 MHz for the USB clock using a Current
Controlled Oscillators (CCO). It is insured that the PLL1 output has a 50 % duty cycle.
8.29.4 RTC clock output
The LPC17xx feature a clock output function intended for synchronizing with external
devices and for use during system development to allow checking the internal clocks
CCLK, IRC clock, main crystal, RTC clock, and USB clock in the outside world. The RTC
clock output allows tuning the RTC frequency without probing the pin, which would distort
the results.
8.29.5 Wake-up timer
The LPC17xx begin operation at power-up and when awakened from Power-down mode
by using the 4 MHz IRC oscillator as the clock source. This allows chip operation to
resume quickly. If the main oscillator or the PLL is needed by the application, software will
need to enable these features and wait for them to stabilize before they are used as a
clock source.
When the main oscillator is initially activated, the wake-up timer allows software to ensure
that the main oscillator is fully functional before the processor uses it as a clock source
and starts to execute instructions. This is important at power on, all types of Reset, and LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 9.5 — 24 June 2014 39 of 89
NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
whenever any of the aforementioned functions are turned off for any reason. Since the
oscillator and other functions are turned off during Power-down mode, any wake-up of the
processor from Power-down mode makes use of the wake-up timer.
The Wake-up Timer monitors the crystal oscillator to check whether it is safe to begin
code execution. When power is applied to the chip, or when some event caused the chip
to exit Power-down mode, some time is required for the oscillator to produce a signal of
sufficient amplitude to drive the clock logic. The amount of time depends on many factors,
including the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its
electrical characteristics (if a quartz crystal is used), as well as any other external circuitry
(e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.
8.29.6 Power control
The LPC17xx support a variety of power control features. There are four special modes of
processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and
Deep power-down mode. The CPU clock rate may also be controlled as needed by
changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider
value. This allows a trade-off of power versus processing speed based on application
requirements. In addition, Peripheral Power Control allows shutting down the clocks to
individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all
dynamic power use in any peripherals that are not required for the application. Each of the
peripherals has its own clock divider which provides even better power control.
Integrated PMU (Power Management Unit) automatically adjust internal regulators to
minimize power consumption during Sleep, Deep sleep, Power-down, and Deep
power-down modes.
The LPC17xx also implement a separate power domain to allow turning off power to the
bulk of the device while maintaining operation of the RTC and a small set of registers for
storing data during any of the power-down modes.
8.29.6.1 Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence but re-enabling the clock to the ARM core.
In Sleep mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
8.29.6.2 Deep-sleep mode
In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Deep-sleep mode and the logic levels of chip pins remain static.
The output of the IRC is disabled but the IRC is not powered down for a fast wake-up later.
The RTC oscillator is not stopped because the RTC interrupts may be used as the
wake-up source. The PLL is automatically turned off and disconnected. The CCLK and
USB clock dividers automatically get reset to zero.LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 9.5 — 24 June 2014 40 of 89
NXP Semiconductors LPC1769/68/67/66/65/64/63
32-bit ARM Cortex-M3 microcontroller
The Deep-sleep mode can be terminated and normal operation resumed by either a
Reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power
consumption to a very low value. Power to the flash memory is left on in Deep-sleep
mode, allowing a very quick wake-up.
On wake-up from Deep-sleep mode, the code execution and peripherals activities will
resume after 4 cycles expire if the IRC was used before entering Deep-sleep mode. If the
main external oscillator was used, the code execution will resume when 4096 cycles
expire. PLL and clock dividers need to be reconfigured accordingly.
8.29.6.3 Power-down mode
Power-down mode does everything that Deep-sleep mode does, but also turns off the
power to the IRC oscillator and the flash memory. This saves more power but requires
waiting for resumption of flash operation before execution of code or data access in the
flash memory can be accomplished.
On the wake-up of Power-down mode, if the IRC was used before entering Power-down
mode, it will take IRC 60 s to start-up. After this 4 IRC cycles will expire before the code
execution can then be resumed if the code was running from SRAM. In the meantime, the
flash wake-up timer then counts 4 MHz IRC clock cycles to make the 100 s flash start-up
time. When it times out, access to the flash will be allowed. Users need to reconfigure the
PLL and clock dividers accordingly.
8.29.6.4 Deep power-down mode
The Deep power-down mode can only be entered from the RTC block. In Deep
power-down mode, power is shut off to the entire chip with the exception of the RTC
module and the RESET pin.
The LPC17xx can wake up from Deep power-down mode via the RESET pin or an alarm
match event of the RTC.
8.29.6.5 Wake-up interrupt controller
The Wake-up Interrupt Controller (WIC) allows the CPU to automatically wake up from
any enabled priority interrupt that can occur while the clocks are stopped in Deep sleep,
Power-down, and Deep power-down modes.
The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When
the CPU enters Deep sleep, Power-down, or Deep power-down mode, the NVIC sends a
mask of the current interrupt situation to the WIC.This mask includes all of the interrupts
that are both enabled and of sufficient priority to be serviced immediately. With this
information, the WIC simply notices when one of the interrupts has occurred and then it
wakes up the CPU.
The WIC eliminates the need to periodically wake up the CPU and poll the interrupts
resulting in additional power savings.
8.29.7 Peripheral power control
A Power Control for Peripherals feature allows individual peripherals to be turned off if
they are not needed in the application, resulting in additional power savings. LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

32-bit ARM Cortex-M3 microcontroller
8.29.8 Power domains
The LPC17xx provide two independent power domains that allow the bulk of the device to
have power removed while maintaining operation of the RTC and the backup Registers.
On the LPC17xx, I/O pads are powered by the 3.3 V (VDD(3V3)) pins, while the
VDD(REG)(3V3) pin powers the on-chip voltage regulator which in turn provides power to the
CPU and most of the peripherals.
Depending on the LPC17xx application, a design can use two power options to manage
power consumption.
The first option assumes that power consumption is not a concern and the design ties the
VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.
The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and
a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator
powered independently from the I/O pad ring enables shutting down of the I/O pad power
supply “on the fly”, while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of
power to operate, which can be supplied by an external battery. The device core power
(VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. Therefore,
there is no power drain from the RTC battery when VDD(REG)(3V3) is available. LPC1769_68_67_66_65_64_63 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

8.30 System control
8.30.1 Reset
Reset has four sources on the LPC17xx: the RESET pin, the Watchdog reset, power-on
reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt
trigger input pin. Assertion of chip Reset by any source, once the operating voltage attains
a usable level, causes the RSTOUT pin to go LOW and starts the wake-up timer (see
description in Section 8.29.5). The wake-up timer ensures that reset remains asserted
until the external Reset is de-asserted, the oscillator is running, a fixed number of clocks
have passed, and the flash controller has completed its initialization. Once reset is
de-asserted, or, in case of a BOD-triggered reset, once the voltage rises above the BOD
threshold, the RSTOUT pin goes HIGH.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the Boot Block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
