The mini AB receptacle allows to connect both a mini A plug or a mini B plug connectors. Figure 2-5 . USB mini A-B Receptacle When connected to a mini B plug, the AT90USB operates as an “USB device” (the ID pin of the plug is unconnected) and when connected to a mini A plug, the AT90USB operates as a “USB host” (the ID pin of the A plug is tied to ground). 2.4.2 Joystick The 4+1 ways joystick offers an easy user interface implementation for a USB application (it can emulate mouse movements, keyboard inputs...). Pushing the push-button causes the corresponding signal to be pulled low, while releasing (not pressed) causes an H.Z state on the signal. The user must enable internal pull-ups on the microcontroller input pins, removing the need for an external pull-up resistors on the push-button. Figure 2-6 .

They are connected to the high nibble of “Port D” of AT90USB (PORTD[4..7]). To light on a LED, the corresponding port pin must drive a high level. To light off a LED, the corresponding port pin must drive a low level. Figure 2-7 . LEDs Implementation schematic Table 2-1 . Leds references 2.4.4 Temperature Sensor The temperature sensor uses a thermistor (R29), or temperature-sensitive resistor. This thermistor have a negative temperature coefficient (NTC), meaning the resistance goes up as temperature goes down. Of all passive temperature measurement sensors, thermistors have the highest sensitivity (resistance change per degree of temperature change). Thermistors do not have a linear temperature/resistance curve. The voltage over the NTC can be found using the A/D converter (connected to channel 0). See the AT90USB Datasheet for how to use the ADC. The thermistor value (RT) is calculate with the following expression: Where: RT = Thermistor value (Ω) at T temperature (°Kelvin) RH = Second resistor of the bridge -100 KΩ ±10% at 25°C VADC0 = Voltage value on ADC-0 input (V) VCC = Board power supply LED Reference AT90USB Connection Color D2 PORTD.4 Red PORTD.5 Green D5 PORTD.6 Green PORTD.7 Red D2 D5 1k R14 1k R17 LEDs In-line Grouped LEDs PD4 PD5 PD7 PD[7..0] PD6 1k R22 1k R23 RT (RH ⋅ VADC0) VCC VADC0 – = ⁄ ( ) Using the AT90USBKey AT90USBKey Hardware User Guide 2-11 7627A–AVR–04/06 The NTC thermistor used in AT90USBKey has a resistance of 100 KΩ ±5% at 25°C (T0) and a beta-value of 4250 ±3%. By the use of the following equation, the temperature (T) can be calculated: Where: RT = Thermistor value (Ω) at T temperature (°Kelvin) ß = 4250 ±3% R0 = 100 KΩ ±5% at 25°C T0 = 298 °K (273 °K + 25°K) The following cross table also can be used. It is based on the above equation. Table 2-2 . Thermistor Values versus Temperature Temp. (°C) RT (KΩ) Temp. (°C) RT (KΩ) Temp. (°C) RT (KΩ) Temp.

This is the easiest and fastest way to reprogram the device directly over the USB interface. The “Flip” PC side application, is available from the Atmel website, offers a flexible an user friendly interface to reprogram the application over the USB bus. The HWB pin of the AT90USB allows to force the bootloader section execution after reset. (Refer to AT90USB datasheet section “boot loader support”). To force bootloader execution, operate as follow: 􀀀 Press both “RST” and “HWB” push buttons 􀀀 First release the “RST” push button 􀀀 Release the “HWB” push button For more information about the USB bootloader and “Flip” application, please refer to the “USB bootloader datasheet document” and “Flip’s user manual”. Note: The HWB pin is active only if the HWBE fuse is set (default factory configuration). 2.5.2 Programming with AVR JTAGICEmKII The AT90USB can be programmed using specific JTAG link. To use the AVR JTAGICEmkII with an AT90USBKey an optional HE10 connector should be soldered to J9 footprint. Then the JTAG probe can be connected to the AT90USBKey as shown in Figure 2-10. Note: When the JTAGEN Fuse is unprogrammed, the four TAP pins are normal port pins, and the TAP controller is in reset. When programmed, the input TAP signals are internally pulled high and the JTAG is enabled for Boundary-scan and programming. The AT90USB device is shipped with this fuse programmed. Using the AT90USBKey 2-14 AT90USBKey Hardware User Guide 7627A–AVR–04/06 Figure 2-10 . Connecting AVR JTAG ICE to AVRUSBKey The Flash, EEPROM and all Fuse and Lock Bit options ISP-programmable can be programmed individually or with the sequential automatic programming option. Note: See AVR Studio® on-line Help for information. 2.6 Debugging 2.6.1 Debugging with AVR JTAG ICE mkII The AT90USBKey can be used for debugging with JTAG ICE MK II. Connect the JTAG ICE mkII as shown in Figure 2-10, for debugging, please refer to AVR Studio® Help information. When using JTAG ICE MK II for debugging, and as AT90USB parts are factory configured with the higher security level set, a chip erase operation will be performed on the part before debugging. Thus the on-chip flash bootloader will be erased. It can be restored after the debug session using the bootloader hex file available from ATMEL website. AT90USBKey Hardware User Guide 3-15 7627A–AVR–04/06 Section 3 Troubleshooting Guide Figure 3-1 . Troubleshooting Guide Problem Reason Solution The Green “VCC-ON” LED is not on No power supply Verify the power supply source (check AVRUSBKey does not battery charge or USB connection). work The AT90USB cannot be programmed The AVR JTAG ICE probe is not connected Connect the JTAG ICE 10-PIN header to the correct AVRUSBKey JTAG header (page 13) The memory lock bits are programmed Erase the memory before programming with JTAG ICE. The fuse bits are wrongly programmed Check the fuse bits with JTAG ICE Can not connect to USB bootloader Force bootloader execution with HWB under reset. USB bootloader erased after a JTAG debugging session: reprogram the USB bootloader with JTAG. AVR Studio does not detect the AVR JTAG ICE. Serial/USB cable is not connected, or power is off Connect serial cable to RS232 (STK500 - AVR ISP) and check power connections Connect serial cable to USB (JATG ICE MKII, AVR ISPmkIIl) and check power connections PC COM port is in use Disable other programs that are using PC COM port. Change PC COM port AVR Studio does not detect COM port. Disable COM port auto-detection in AVR Studio file menu.

recommended for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC–. (3) The magnitude of the input voltage must never exceed the magnitude of the supply voltage. (4) Excessive input current will flow if a differential input voltage in excess of approximately 0.6 V is applied between the inputs, unless some limiting resistance is used. (5) The output may be shorted to ground or either power supply. Temperature and/or supply voltages must be limited to ensure the maximum dissipation rating is not exceeded. (6) The package thermal impedance is calculated in accordance with JESD 51-7. (7) Maximum power dissipation is a function of TJ(max), qJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) - TA)/qJA. Operating at the absolute maximum TJ of 150°C can affect reliability. 2 Submit Documentation Feedback Copyright © 1979–2009, Texas Instruments Incorporated Product Folder Link(s): NE5532 NE5532A SA5532 SA5532A RECOMMENDED OPERATING CONDITIONS ELECTRICAL CHARACTERISTICS NE5532, NE5532A SA5532, SA5532A www.ti.com...................................................................................................................................................

The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good indication of device performance. Note 3: For operation in ambient temperatures above 25°C, the device must be derated based on a 150°C maximum junction temperature and 1) a thermal resistance of 107°C/W junction to ambient for the dual-in-line package and 2) a thermal resistance of 170°C/W for the small outline package. LM386 www.national.com 2 Application Hints GAIN CONTROL To make the LM386 a more versatile amplifier, two pins (1 and 8) are provided for gain control. With pins 1 and 8 open the 1.35 kW resistor sets the gain at 20 (26 dB). If a capacitor is put from pin 1 to 8, bypassing the 1.35 kW resistor, the gain will go up to 200 (46 dB). If a resistor is placed in series with the capacitor, the gain can be set to any value from 20 to 200. Gain control can also be done by capacitively coupling a resistor (or FET) from pin 1 to ground. Additional external components can be placed in parallel with the internal feedback resistors to tailor the gain and frequency response for individual applications. For example, we can compensate poor speaker bass response by frequency shaping the feedback path. This is done with a series RC from pin 1 to 5 (paralleling the internal 15 kW resistor). For 6 dB effective bass boost: R . 15 kW, the lowest value for good stable operation is R = 10 kW if pin 8 is open. If pins 1 and 8 are bypassed then R as low as 2 kW can be used. This restriction is because the amplifier is only compensated for closed-loop gains greater than 9. INPUT BIASING The schematic shows that both inputs are biased to ground with a 50 kW resistor. The base current of the input transistors is about 250 nA, so the inputs are at about 12.5 mV when left open. If the dc source resistance driving the LM386 is higher than 250 kW it will contribute very little additional offset (about 2.5 mV at the input, 50 mV at the output). If the dc source resistance is less than 10 kW, then shorting the unused input to ground will keep the offset low (about 2.5 mV at the input, 50 mV at the output). For dc source resistances between these values we can eliminate excess offset by putting a resistor from the unused input to ground, equal in value to the dc source resistance. Of course all offset problems are eliminated if the input is capacitively coupled. When using the LM386 with higher gains (bypassing the 1.35 kW resistor between pins 1 and 8) it is necessary to bypass the unused input, preventing degradation of gain and possible instabilities. This is done with a 0.1 μF capacitor or a short to ground depending on the dc source resistance on the driven input.

Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the LM2902), and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage. Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational-amplifier circuits that now can be more easily implemented in single-supply-voltage systems. For example, the LM124 can be operated directly from the standard 5-V supply that is used in digital systems and provides the required interface electronics, without requiring additional ±15-V supplies.

The package thermal impedance is calculated in accordance with JESD 51-7. 6. Maximum power dissipation is a function of TJ(max), JC, and TC. The maximum allowable power dissipation at any allowable case temperature is PD = (TJ(max) − TC)/JC. Operating at the absolute maximum TJ of 150°C can affect reliability. 7. The package thermal impedance is calculated in accordance with MIL-STD-883.

for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.

Associated Script and Description 3.2.3 Control Categories The Digital Settings, Analog Settings, and Signal Processing categories provide control of many registers and other features of the TLV320AIC3254 . These categories are intended for the advanced user. Hovering the mouse cursor on top of a control displays a tip strip that contains page, register, and bit information. As an example, hovering on top of IN1_R of the Audio Inputs panel, as shown in Figure 9 displays p1_r55_b7-6 which means that this control writes to Page 1/Register 55/Bits D7 to D6. 10 TLV320AIC3254EVM-U SLAU295A–September 2009–Revised October 2012 Submit Documentation Feedback Copyright © 2009–2012, Texas Instruments Incorporated www.ti.com AIC3254EVM-U Control Software Figure 9. Tip Strip Example Before changing a control, see the data sheet to ensure that a particular control is compatible with the current state of the codec. As an example, some controls in the Analog Setup panel must be modified in a particular order as described in the data sheet. Other controls must only be modified with a specific hardware setup, such as powering up the AVDD LDO. All controls update their status with respect to the register contents in the following conditions: • A panel is opened. • The Execute Command Buffer button in the Command-Line Interface is pressed (if enabled). • The Refresh button at the bottom right of a panel is pressed SLAU295A–September 2009–Revised October 2012 TLV320AIC3254EVM-U 11 Submit Documentation Feedback Copyright © 2009–2012, Texas Instruments Incorporated AIC3254EVM-U Control Software www.ti.com 3.2.4 Status Flags Panel The TLV320AIC3254 status flags can monitored in the Status Flags panel (Figure 10) which is located below in the Panel Selection Tree . Pressing the POLL button continuously reads all the registers relevant to each flag and updates those flags accordingly. The rate at which the registers are read can be modified by changing the value in the Polling Interval numeric control. Note that a smaller interval reduces responsiveness of other controls, especially volume sliders, due to bandwidth limitations. By default, the polling interval is 200 ms and can be set to a minimum of 20 ms. The Sticky Flags tab contains indicators whose corresponding register contents clear every time a read is performed to that register. To read all the sticky flags, click the Read Sticky Flags button.

The Page Number control changes to the page to be displayed in the register table. The register table contains page information such as the register name, reset value, current value, and a bitmap of the current value. The contents of the selected page can be exported into a spreadsheet by clicking the Dump to Spreadsheet button. Figure 11.

The TAS1020B USB Controller handles all communication between the PC and the TLV320AIC3254. A script is loaded into the command buffer, either by loading a script file using the File menu or by pasting text from the clipboard using the Ctrl-V key combination (Figure 12). When the command buffer is executed, the return data packets which result from each individual command are displayed in the Command History control. This control is an array (with a maximum size of 100 elements) that contains information about each command as well as status. The Interface box displays the interface used for a particular command in the Command History array. The Command box displays the type of command executed (i.e., write, read) for a particular interface. The Flag Retries box displays the number of read iterations performed by a Wait for Flag command (see Appendix C for details). The Register Data array displays the register number and data bytes that correspond to a particular command. The Information tab provides additional information related to the Command History as well as additional settings. The Syntax and Examples tabs provide useful information related to the scripting language. The File menu provides some options for working with scripts. The first option, Open Script File..., loads a command file script into the command buffer. This script can then be executed by pressing the Execute Command Buffer button. The contents of the Command Buffer can be saved using the Save Script File... option. Both the Command Buffer and Command History can be cleared by clicking their corresponding Clear buttons Figure 12.

Each line in a script file is one command. No provision is made for extending lines beyond one line, except for the > command. A line is terminated by a carriage return. The first character of a line is the command. Commands are: I Set interface bus to use r Read from the serial control bus w Write to the serial control bus > Extend repeated write commands to lines below a w # Comment b Break d Delay f Wait for Flag The first command, I, sets the interface to use for the commands to follow. This command must be followed by one of the following parameters: i2cstd Standard mode I2C bus i2cfast Fast mode I2C bus spi8 SPI bus with 8-bit register addressing spi16 SPI bus with 16-bit register addressing For example, if a fast mode I2C bus is to be used, the script begins with: I i2cfast A double quoted string of characters following the b command can be added to provide information to the user about each breakpoint. When the script is executed, the software's command handler halts as soon as a breakpoint is detected and displays the string of characters within the double quotes. The Wait for Flag command, f, reads a specified register and verifies if the bitmap provided with the command matches the data being read. If the data does not match, the command handler retries for up to 200 times. This feature is useful when switching buffers in parts that support the adaptive filtering mode. The command f syntax follows: f [i2c address] [register] [D7][D6][D5][D4][D3][D2][D1][D0] where 'i2c address' and 'register' are in hexadecimal format and 'D7' through 'D0' are in binary format with values of 0, 1 or X for don't care. Anything following a comment command # is ignored by the parser, provided that it is on the same line. The delay command d allows the user to specify a time, in milliseconds, that the script pauses before proceeding. The delay time is entered in decimal format. A series of byte values follows either a read or write command. Each byte value is expressed in hexadecimal, and each byte must be separated by a space. Commands are interpreted and sent to the TAS1020B by the program. The first byte following an r (read) or w (write) command is the I2C slave address of the device (if I2C is used) or the first data byte to write (if SPI is usednote that SPI interfaces are not standardized on protocols, so the meaning of this byte varies with the device being addressed on the SPI bus). The second byte is the starting register address that data will be written to (again, with I2C; SPI varies. Following these two bytes are data, if writing; if reading, the third byte value is the number of bytes to read, (expressed in hexadecimal). 18 Writing Scripts SLAU295A–September 2009–Revised October 2012 Submit Documentation Feedback Copyright © 2009–2012, Texas Instruments Incorporated www.ti.com Appendix C For example, to write the values 0xAA 0x55 to an I2C device with a slave address of 0x30, starting at a register address of 0x03, the user writes: #example script I i2cfast w 30 03 AA 55 r 30 03 02 This script begins with a comment, specifies that a fast I2C bus will be used, then writes 0xAA 0x55 to the I2C slave device at address 0x30, writing the values into registers 0x03 and 0x04. The script then reads back two bytes from the same device starting at register address 0x03. Note that the slave device value does not change. It is unnecessary to set the R/W bit for I2C devices in the script; the read or write commands does that. If extensive repeated write commands are sent and commenting is desired for a group of bytes, the > command can be used to extend the bytes to other lines that follow. A usage example for the > command follows: #example script for '>' command I i2cfast # Write AA and BB to registers 3 and 4, respectively w 30 03 AA BB # Write CC, DD, EE and FF to registers 5, 6, 7 and 8, respectively > CC DD EE FF # Place a commented breakpoint b "AA BB CC DD EE FF was written, starting at register 3" # Read back all six registers, starting at register 3 r 30 03 06 The following example demonstrates usage of the Wait for Flag command, f: #example script for 'wait for flag' command I i2cfast # Switch to Page 44 w 30 00 2C # Switch buffers w 30 01 05 # Wait for bit D0 to clear. 'x' denotes a don't care. f 30 01 xxxxxxx0 Any text editor can be used to write these scripts; Jedit is an editor that is highly recommended for general usage. For more information, go to: http://www.jedit.org. Once the script is written, it can be used in the command window by running the program, and then selecting Open Script File... from the File menu. Locate the script and open it. The script is then displayed in the command buffer. The user can also edit the script once it is in the buffer and save it by selecting Save Script File... from the File menu.

If there are breakpoints in the script, the script executes to that point, and the user is presented with a dialog box with a button to press to continue executing the script. When ready to proceed, push that button and the script continues. 20 Writing Scripts SLAU295A–September 2009–Revised October 2012 Submit Documentation Feedback Copyright © 2009–2012, Texas Instruments Incorporated EVALUATION BOARD/KIT IMPORTANT NOTICE Texas Instruments (TI) provides the enclosed product(s) under the following conditions: This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use.

Figure 5 shows the power dissipated in a typical SN75372 as a function of load capacitance and frequency. Average power dissipated by this driver is derived from the equation PT(AV) = PDC(AV) + PC(AV) = PS(AV) where PDC(AV) is the steady-state power dissipation with the output high or low, PC(AV) is the power level during charging or discharging of the load capacitance, and PS(AV) is the power dissipation during switching between the low and high levels. None of these include energy transferred to the load, and all are averaged over a full cycle. The power components per driver channel are PC(AV)  C V2 C f tHL tLH tH tL T = 1/f where the times are as defined in Figure 14. Figure 12. Output Voltage Waveform PDC(AV) = PHtH + PLtL T PS(AV) = PLHtLH + PHLtHL T PL, PH, PLH, and PHL are the respective instantaneous levels of power dissipation, C is the load capacitance. VC is the voltage across the load capacitance during the charge cycle shown by the equation VC = VOH − VOL PS(AV) may be ignored for power calculations at low frequencies. In the following power calculation, both channels are operating under identical conditions: VOH =19.2 V and VOL = 0.15 V with VCC1 = 5 V, VCC2 = 20 V, VC = 19.05 V, C = 1000 pF, and the duty cycle = 60%. At 0.5 MHz, PS(AV) is negligible and can be ignored. When the output voltage is high, ICC2 is negligible and can be ignored.

The input impedance of a FET consists of a reverse biased PN junction that can be described as a large capacitance in parallel with a very high resistance. For this reason, the commonly used open-collector driver with a pullup resistor is not satisfactory for high-speed applications. In Figure 12(a), an IRF151 power MOSFET switching an inductive load is driven by an open-collector transistor driver with a 470-Ω pullup resistor. The input capacitance (Ciss) specification for an IRF151 is 4000 pF maximum. The resulting long turn-on time due to the combination of Ciss and the pullup resistor is shown in Figure 12(b). 5 V 7 4 8 3 5 2 1 6 VVO0HH − − Gate Voltage − V TLC555P 1/2 SN75447 470 Ω 48 V M VOL t − Time − μs (b) (a) IRF151 4 3 2 1 0 0 0.5 1 1.5 2 2.5 3 Figure 13.

Power MOSFET Drive Using SN75372 Power MOSFET drivers must be capable of supplying high peak currents to achieve fast switching speeds as shown by the equation Ipk  VC tr where C is the capacitive load, and tr is the desired drive time. V is the voltage that the capacitance is charged to. In the circuit shown in Figure 13(a), V is found by the equation V = VOH − VOL Peak current required to maintain a rise time of 100 ns in the circuit of Figure 13(a) is IPK  (30)4(109) 100(109)  120 mA Circuit capacitance can be ignored because it is very small compared to the input capacitance of the IRF151. With a VCC of 5 V, and assuming worst-cast conditions, the gate drive voltage is 3 V. For applications in which the full voltage of VCC2 must be supplied to the MOSFET gate, the SN75374 quad MOSFET driver should be used.

Each transceiver is designed to provide the bus-management and data-transfer signals between operating units of a single- or multiple-controller instrumentation system. When combined with the SN75160B octal bus transceiver, the SN75161B or SN75162B provides the complete 16-wire interface for the IEEE-488 bus. The SN75161B and SN75162B feature eight driver-receiver pairs connected in a front-to-back configuration to form input/output (I/O) ports at both the bus and terminal sides. A powerup/- down disable circuit is included on all bus and receiver outputs. This provides glitch-free operation during VCC power up and power down.

The SC input on the SN75162B allows the REN and IFC transceivers to be controlled independently. The driver outputs (GPIB I/O ports) feature active bus-terminating resistor circuits designed to provide a high impedance to the bus when supply voltage VCC is 0. The drivers are designed to handle loads up to 48 mA of sink current. Each receiver features pnp transistor inputs for high input impedance and hysteresis of 400 mV for increased noise immunity. All receivers have 3-state outputs to present a high impedance to the terminal when disabled. The SN75161B and SN75162B are characterized for operation from 0°C to 70°C.

Layout Used For No Heat Sink Measurements Figure 5. Layout Used For Measurements With Small Heat Sink LMT88 TRANSFER FUNCTION The LMT88 transfer function can be described in different ways with varying levels of precision. A simple linear transfer function, with good accuracy near 25°C, is VO = −11.69 mV/°C × T + 1.8663 V (1) Over the full operating temperature range of −55°C to 130°C, best accuracy can be obtained by using the parabolic transfer function. VO = (−3.88×10−6×T2) + (−1.15×10−2×T) + 1.8639 (2) solving for T: (3) A linear transfer function can be used over a limited temperature range by calculating a slope and offset that give best results over that range. A linear transfer function can be calculated from the parabolic transfer function of the LMT88. The slope of the linear transfer function can be calculated using the following equation: m = −7.76 × 10−6× T − 0.0115, (4) where T is the middle of the temperature range of interest and m is in V/°C. For example for the temperature range of TMIN = −30 to TMAX = +100°C: T = 35°C (5) and m = −11.77 mV/°C (6) The offset of the linear transfer function can be calculated using the following equation: b = (VOP(TMAX) + VOP(T) − m × (TMAX+T))/2 (7) where: VOP(TMAX) is the calculated output voltage at TMAX using the parabolic transfer function for VO VOP(T) is the calculated output voltage at T using the parabolic transfer function for VO. Using this procedure the best fit linear transfer function for many popular temperature ranges was calculated in Table 2. As shown in Table 2 the error that is introduced by the linear transfer function increases with wider temperature ranges.

It can be glued or cemented to a surface. The temperature that the LMT88 is sensing will be within about +0.02°C of the surface temperature to which the LMT88's leads are attached to. This presumes that the ambient air temperature is almost the same as the surface temperature; if the air temperature were much higher or lower than the surface temperature, the actual temperature measured would be at an intermediate temperature between the surface temperature and the air temperature. To ensure good thermal conductivity the backside of the LMT88 die is directly attached to the pin 2 GND pin. The tempertures of the lands and traces to the other leads of the LMT88 will also affect the temperature that is being sensed. Alternatively, the LMT88 can be mounted inside a sealed-end metal tube, and can then be dipped into a bath or screwed into a threaded hole in a tank. As with any IC, the LMT88 and accompanying wiring and circuits must be kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may operate at cold temperatures where condensation can occur. Printed-circuit coatings and varnishes such as Humiseal and epoxy paints or dips are often used to ensure that moisture cannot corrode the LMT88 or its connections. The thermal resistance junction to ambient (θJA) is the parameter used to calculate the rise of a device junction temperature due to its power dissipation. For the LMT88 the equation used to calculate the rise in the die temperature is as follows: TJ = TA + θJA [(V+ IQ) + (V+ − VO) IL] where IQ is the quiescent current and ILis the load current on the output. Since the LMT88's junction temperature is the actual temperature being measured care should be taken to minimize the load current that the LMT88 is required to drive. 6 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: LMT88 OUT Heavy Capacitive Load, Wiring, Etc.

CAPACITIVE LOADS The LMT88 handles capacitive loading well. Without any precautions, the LMT88 can drive any capacitive load less than 300 pF as shown in Figure 6. Over the specified temperature range the LMT88 has a maximum output impedance of 160 Ω. In an extremely noisy environment it may be necessary to add some filtering to minimize noise pickup. It is recommended that 0.1 μF be added from V+ to GND to bypass the power supply voltage, as shown in . In a noisy environment it may even be necessary to add a capacitor from the output to ground with a series resistor as shown in . A 1 μF output capacitor with the 160 Ω maximum output impedance and a 200 Ω series resistor will form a 442 Hz lowpass filter. Since the thermal time constant of the LMT88 is much slower, the overall response time of the LMT88 will not be significantly affected. Figure 6.

APPLICATION CIRCUITS Figure 8. Centigrade Thermostat Figure 9. Conserving Power Dissipation with Shutdown Figure 10. Suggested Connection to a Sampling Analog to Digital Converter Input Stage Most CMOS ADCs found in ASICs have a sampled data comparator input structure that is notorious for causing grief to analog output devices such as the LMT88 and many op amps. The cause of this grief is the requirement of instantaneous charge of the input sampling capacitor in the ADC. This requirement is easily accommodated by the addition of a capacitor. Since not all ADCs have identical input stages, the charge requirements will vary necessitating a different value of compensating capacitor. This ADC is shown as an example only.

The SN65LVDS100 and SN65LVDS101 devices both incorporate wide common-mode range receivers, allowing receipt of LVDS, LVPECL, or CML input signals. The SN65LVDS100 provides an LVDS output, the SN65LVDS101 incorporates an LVPECL output driver, and the SN65CML100 delivers a CML output. Both devices provide a VBB reference voltage to support receiving of single-ended LVPECL input signals, or biasing of ac-coupled inputs. The EVM can be ordered with the SN65LVDS100, SN65LVDS101, or SN65CML100 installed. Orderable EVM part numbers are shown in Table 1-1. Table 1-1.

LVDS drivers nominally provide a 350-mV differential signal, with a 1.25-V offset from ground. These levels are attained when driving a 100-Ω differential line-termination test load (see Figure 2-1). In real applications, there may be a ground potential between a driver and receiver(s). The driver must drive the common-mode load presented by the receiver inputs and the differential load. A TIA/EIA-644-A compliant LVDS driver is required to maintain its differential output with up to 32 standard receivers. The receiver load is represented by the 3.74-kΩ resistors shown in Figure 2-1. Figure 2-1. TIA/EIA-644-A LVDS Driver Test Load _ + A B VOD 100 Ω 3.74 kΩ 3.74 kΩ 0 V ≤ Vtest ≤ 2.4 V D LVPECL drivers are generally loaded with 50-Ω resistors to a termination bias voltage, VT. VT is usually 2-V below the supply voltage of the driver circuit. When the driver operates from a 3.3-V supply, VT is set to approximately 1.3 V. CML drivers are generally loaded with 50-Ω resistors to a termination voltage, VTT. VTT can either be equivalent to the supply voltage of the driver circuit (equal to VCC) or set to 2.5 V or 1.8 V, irrelevant to the supply voltage. If desired, the SN65CML100 can be configured to drive a dual 50-Ω load. In this configuration one 50-Ω resistor (tied to the termination voltage VTT) is placed near the output of the SN65CML100 and a second 50-Ω resistor (also tied to VTT) is placed near the end of the transmission line. The EVM has been designed to support the SN65LVDS100 LVDS-output device, the SN65LVDS101 LVPECL-output device, and the SN65CML100 CML-output device. By using the three power jacks (J1, J2, and J3), as well as installing termination resistors (R2, R3, and R4), different methods of termination and probing can be used to evaluate the device output characteristics. The typical setup for the SN65LVDS100 is shown in Figure 2-2. Applying an Input Setup and Equipment Required 2-3 Figure 2-2. EVM Power Connections for SN65LVDS100 Evaluation Pattern Generator Oscilloscope EVM Power Supply 1 + - Power Supply 2 + - EVM VCC GND DUT GND 1.22V 3.3V Matched Cables SMA to SMA Matched Cables SMA to SMA J2 J7 J6 J5 J4 J3 J1 100 Ω 50 Ω 50 Ω Warning Power jacks J1, J2, and J3 are not insulated on the backside of the EVM. Place on a nonconductive surface. 2.2 Applying an Input LVDS inputs should be applied to SMA connectors J4 and J5, while keeping R1 installed. The EVM comes with a 100-Ω termination resistor (R1) installed across the differential inputs. This 100-Ω resistor represents an LVDS termination. When using a general-purpose signal generator with 50-Ω output impedance, make sure that the signal levels are between 0 V to 4 V with respect to J3. A signal generator such as the Advantest D3186 can simulate LVDS, LVPECL, or CML inputs. When using LVPECL or CML drivers for the input signal, termination external to the EVM must be provided (see Figure 2-3). LVPECL drivers should be terminated with 50-Ω pulldowns to VT, while CML drivers should be terminated Applying an Input 2-4 with 50-Ω pullups to VTT. When using external terminations, the onboard termination resistor R1 should be removed from the EVM. It should be noted that the signal quality at the receiver input may be degraded when external terminations are used, as a significant stub exists from the external termination network to the receiver input. The user needs to verify that the transition time of the input signal, coupled with the stub length, does not lead to reflection problems. These concerns would be addressed in a real application where the terminations are placed close to the receiver input. Figure 2-3.

Locate 50-Ω resistors as close to the EVM as possible B. Remove R1 A B Y Z Finally, as mentioned above, the SN65LVDS100, SN65LVDS101, and SN65CML100 devices provide a VBB reference voltage output. This output can be used with an externally terminated, single-ended, LVPECL input to convert from a single-ended input to a differential output. The same cautions that are mentioned above concerning signal quality and reflections apply. When using VBB as a single-ended reference, R1 should be removed while R5 and JMP2 should be installed. The single-ended input signal is applied to J4. This setup directly connects the VBB output to the DUT receiver B input via a 0-Ω connection (see Figure 2-4). Observing an Output Setup and Equipment Required 2-5 Figure 2-4. External Termination for Single-Ended LVPECL Inputs to EVM 50 Ω OUT Signal Source EVM BOARD NOTES: A. Add jumper Jmp2 and 0-Ω R5 B. Remove R1 A B Y Z 2.3 Observing an Output Direct connection to an oscilloscope with 50-Ω internal terminations to ground is accomplished without R2, R3, and R41. The outputs are available at J6 and J7 for direct connection to oscilloscope inputs. Matched length cables must be used when connecting the EVM to a scope to avoid inducing skew between the noninverting (+) and inverting (-) outputs. The three power jacks (J1, J2, and J3) are used to provide power and a ground reference for the EVM. The power connections to the EVM determine the common-mode load to the device. As mentioned earlier, LVDS drivers have limited common-mode driver capability. When connecting the EVM outputs directly to oscilloscope inputs, setting of the oscilloscope common-mode offset voltage is required, as the oscilloscope presents low common-mode load impedance to the device. Returning to Figure 2-2, power supply 1 is used to provide the required 3.3 V to the EVM. Power supply 2 is used to offset the EVM ground relative to the DUT ground. The EVM ground is connected to the oscilloscope ground through the returns on SMA connectors J6 and J7. With power applied as shown in Figure 2-2, the common-mode voltage seen by the SN65LVDS100 is approximately equal to the reference voltage being used inside the device preventing significant common-mode current to flow. Optimum device setup can be confirmed by adjusting the voltage on power supply 2 until its current is minimized. It is important to note that use of the dual supplies and offsetting the EVM ground relative to the DUT ground are simply steps needed for the test and evaluation of devices. Actual designs would include high-impedance receivers, which would not require the setup steps outlined above. 1 As delivered R2, R3, and R4 are not installed Typical Test Results 2-6 LVPECL drivers need a 50-Ω termination to VT. A modification of Figure 2-2 and the above instructions are used when evaluating an SN65LVDS101 with a direct connection to a 50-Ω oscilloscope. With power supply 1 in Figure 2-2 set to 3.3 V, power supply 2 should be set to 1.3 V (2 V below VCC) to provide the correct termination voltage. CML drivers need a 50-Ω termination to VTT (VTT is either VCC, 2.5 V, or 1.8 V). A modification of Figure 2-2 and the instructions for the SN65LVDS100 are used when evaluating a SN65CML100 with direct connection to a 50-Ω oscilloscope. With power supply 1 in Figure 2-2 set to 3.3 V, power supply 2 should be set to either VCC (3.3 V), 2.5 V, or 1.8 V to provide the correct termination voltage. Dual termination of the output can be achieved by placing 49.9-Ω resistors at R2 and R3 and connecting to an oscilloscope as described above. If the EVM outputs are to be evaluated with a high-impedance probe, direct probing on the EVM is supported via installation of R2, R3, and R4. LVDS outputs can be observed by installing R4, a 100-Ω resistor. LVPECL outputs can be observed by installing R2 and R3 (49.9-Ω resistors), and setting power supply 2 to 1.3 V. CML outputs can be observed by setting power supply 2 to VTT and installing 49.9-Ω resistors at R2 and R3 for single termination, or 24.9-Ω resistors at R2 and R3 for dual termination (Note that power supply 2 must be able to sink current.) 2.4 Typical Test Results Figure 2-5 shows a typical test result obtained with the EVM. Figure 2-5 shows the output of an SN65LVDS100 being driven directly into a 50-Ω oscilloscope. For this figure, the SN65LVDS100 was stimulated with an HP 3-GBPS BERT. The input data was pseudorandom data at 2 GBPS and with a random record length of 223-1. The BERT drove two electrically matched one-meter cables with an electrical length of 3.667 ns. These cables were then connected to the EVM inputs. The EVM outputs were connected through another set of electrically matched one-meter cables and terminated by a TDS8000 oscilloscope’s 50-Ω resistors to ground.

This family is code-compatible with previous C28x-based code, as well as providing a high level of analog integration. An internal voltage regulator allows for single rail operation. Analog comparators with internal 6-bit references have been added and can be routed directly to control the PWM outputs. The ADC converts from 0 to 3.3-V fixed full scale range and supports ratio-metric VREFHI/VREFLO references. The ADC interface has been optimized for low overhead/latency. The Analog Front End (AFE) contains up to seven comparators with up to three integrated Digital-to- Analog Converters (DACs), one VREFOUT-buffered DAC, up to four Programmable Gain Amplifiers (PGAs), and up to four digital filters. The Programmable Gain Amplifiers (PGAs) are capable of amplifying the input signal in three discrete gain modes. The actual gain itself depends on the resistors defined by the user at the bipolar input end. The actual number of AFE peripherals will depend upon the 2805x device number. See Table 2-1 for more details. 2 TMS320F2805x ( Piccolo™) MCUs Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION M0 SARAM 1Kx16 (0-wait) 16-bit Peripheral Bus M1 SARAM 1Kx16 (0-wait) SCI-A, B C (4L FIFO) SCI- , SCI- SPISIMOA SPISOMIA SPICLKA SPISTEA ePWM1–ePWM7 SPI-A (4L FIFO) I2C-A (4L FIFO) 32-Bit Peripheral Bus GPIO MUX C28x CPU (60 MHz) PIE (up to 96 interrupts) CPU Timer 0 CPU Timer 1 CPU Timer 2 TRST TCK TDI TMS TDO OSC1, OSC2, Ext, PLL, LPM, WD X2 32-bit Peripheral Bus (CLA-accessible) EPWMxA EPWMxB SDAx SCLx SCIRXDx GPIO Mux LPM Wakeup CLA + Message RAMs ADC 0-wait Result Regs Boot ROM 12Kx16 (0-wait) Non-Secure L0 SARAM (2Kx16) (0-wait, Secure) CLA Data RAM2 COMP + Digital COMPAn Filter COMPBn 32-bit Peripheral Bus (CLA-accessible) eCAN-A (32-mbox) eCAP ECAPx CANTXx CANRXx eQEP EQEPxA EQEPxB EQEPxI EQEPxS SCITXDx X1 GPIO MUX Program- mable Gain Amps VREG POR/ BOR Memory Bus Memory Bus TZx Secure ROM (A) 2Kx16 (0-wait) Secure L1 DPSARAM (1Kx16) (0-wait, Secure) CLA Data RAM0 L2 DPSARAM (1Kx16) (0-wait, Secure) CLA Data RAM1 L3 DPSARAM (4Kx16) (0-wait, Secure) CLA Program RAM CLA Data ROM (4Kx16) CTRIPnOUT ADC 3.75 MSPS 32-bit Peripheral Bus (CLA-accessible) CLA Bus XRS GPIO Mux XCLKIN 3 External Interrupts Memory Bus EPWMSYNCI EPWMSYNCO PSWD Dual- Zone Security Module + ECSL OTP/Flash Wrapper Z1/Z2 User OTP Secure PUMP FLASH 28055, 28054: 64K x 16, 10 Sectors 28053, 28052, 28051: 32K x 16, 5 Sectors 28050: 16K x 16, 3 Sectors Secure TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 1.3 Functional Block Diagram A.

The protected mode makes sure that all accesses to these blocks happen as written. Because of the pipeline, a write immediately followed by a read to different memory locations will appear in reverse order on the memory bus of the CPU. This action can cause problems in certain peripheral applications where the user expected the write to occur first (as written). The CPU supports a block protection mode where a region of memory can be protected so that operations occur as written (the penalty is extra cycles are added to align the operations). This mode is programmable, and by default, it protects the selected zones. The wait-states for the various spaces in the memory map area are listed in Table 2-5. Table 2-5.

The C28xbased controllers have the same 32-bit fixed-point architecture as existing C28x MCUs. Each C28x-based controller, including the 2805x device, is a very efficient C/C++ engine, enabling users to develop not only their system control software in a high-level language, but also enabling development of math algorithms using C/C++. The device is as efficient at MCU math tasks as it is at system control tasks. This efficiency removes the need for a second processor in many systems. The 32 x 32-bit MAC 64-bit processing capabilities enable the controller to handle higher numerical resolution problems efficiently. Add to this feature the fast interrupt response with automatic context save of critical registers, resulting in a device that is capable of servicing many asynchronous events with minimal latency. The device has an 8-leveldeep protected pipeline with pipelined memory accesses. This pipelining enables the device to execute at high speeds without resorting to expensive high-speed memories. Special branch-look-ahead hardware minimizes the latency for conditional discontinuities. Special store conditional operations further improve performance. 2.3.2 Control Law Accelerator (CLA) The C28x control law accelerator is a single-precision (32-bit) floating-point unit that extends the capabilities of the C28x CPU by adding parallel processing. The CLA is an independent processor with its own bus structure, fetch mechanism, and pipeline. Eight individual CLA tasks, or routines, can be specified. Each task is started by software or a peripheral such as the ADC, ePWM, eCAP, eQEP, or CPU Timer 0. The CLA executes one task at a time to completion. When a task completes the main CPU is notified by an interrupt to the PIE and the CLA automatically begins the next highest-priority pending task. The CLA can directly access the ADC Result registers, ePWM, eCAP, eQEP, and the Comparator and DAC registers. Dedicated message RAMs provide a method to pass additional data between the main CPU and the CLA. 2.3.3 Memory Bus (Harvard Bus Architecture) As with many MCU-type devices, multiple busses are used to move data between the memories and peripherals and the CPU. The memory bus architecture contains a program read bus, data read bus, and data write bus. The program read bus consists of 22 address lines and 32 data lines. The data read and write busses consist of 32 address lines and 32 data lines each. The 32-bit-wide data busses enable single cycle 32-bit operations. The multiple bus architecture, commonly termed Harvard Bus, enables the C28x to fetch an instruction, read a data value and write a data value in a single cycle. All peripherals and memories attached to the memory bus prioritize memory accesses. Generally, the priority of memory bus accesses can be summarized as follows: Highest: Data Writes (Simultaneous data and program writes cannot occur on the memory bus.) Program Writes (Simultaneous data and program writes cannot occur on the memory bus.) Data Reads Program Reads (Simultaneous program reads and fetches cannot occur on the memory bus.) Lowest: Fetches (Simultaneous program reads and fetches cannot occur on the memory bus.)

The peripheral bus bridge multiplexes the various busses that make up the processor Memory Bus into a single bus consisting of 16 address lines and 16 or 32 data lines and associated control signals. Three versions of the peripheral bus are supported. One version supports only 16-bit accesses (called peripheral frame 2). Another version supports both 16- and 32-bit accesses (called peripheral frame 1). The third version supports CLA access and both 16- and 32-bit accesses (called peripheral frame 3). 2.3.5 Real-Time JTAG and Analysis The devices implement the standard IEEE 1149.1 JTAG (1) interface for in-circuit based debug. Additionally, the devices support real-time mode of operation allowing modification of the contents of memory, peripheral, and register locations while the processor is running and executing code and servicing interrupts. The user can also single step through non-time-critical code while enabling timecritical interrupts to be serviced without interference. The device implements the real-time mode in hardware within the CPU. This feature is unique to the 28x family of devices, and requires no software monitor. Additionally, special analysis hardware is provided that allows setting of hardware breakpoint or data/address watch-points and generating various user-selectable break events when a match occurs. These devices do not support boundary scan; however, IDCODE and BYPASS features are available if the following considerations are taken into account. The IDCODE does not come by default. The user needs to go through a sequence of SHIFT IR and SHIFT DR state of JTAG to get the IDCODE. For BYPASS instruction, the first shifted DR value would be 1. 2.3.6 Flash The F28055 and F28054 devices contain 64K x 16 of embedded flash memory, segregated into six 8K x 16 sectors and four 4K x 16 sectors. The F28053, F28052, and F28051 devices contain 32K x 16 of embedded flash memory, segregated into three 8K x 16 sectors and two 4K x 16 sectors. The F28050 device contains 16K x 16 of embedded flash memory, segregated into one 8K x 16 sector and two 4K x 16 sectors. The devices also contain a single 1K x 16 of OTP memory at address range 0x3D 7800 – 0x3D 7BFF. The user can individually erase, program, and validate a flash sector while leaving other sectors untouched. However, it is not possible to use one sector of the flash or the OTP to execute flash algorithms that erase or program other sectors. Special memory pipelining is provided to enable the flash module to achieve higher performance. The flash/OTP is mapped to both program and data space; therefore, the flash/OTP can be used to execute code or store data information. NOTE The Flash and OTP wait-states can be configured by the application. This feature allows applications running at slower frequencies to configure the flash to use fewer wait-states. Flash effective performance can be improved by enabling the flash pipeline mode in the Flash options register. With this mode enabled, effective performance of linear code execution will be much faster than the raw performance indicated by the wait-state configuration alone. The exact performance gain when using the Flash pipeline mode is application-dependent. For more information on the Flash options, Flash wait-state, and OTP wait-state registers, see the System Control and Interrupts chapter of the TMS320x2805x Piccolo Technical Reference Manual (literature number SPRUHE5).

The stack pointer points to the beginning of block M1 on reset. The M0 and M1 blocks, like all other memory blocks on C28x devices, are mapped to both program and data space. Hence, the user can use M0 and M1 to execute code or for data variables. The partitioning is performed within the linker. The C28x device presents a unified memory map to the programmer, which makes for easier programming in high-level languages. 2.3.8 L0 SARAM, and L1, L2, and L3 DPSARAMs The device contains up to 8K x 16 of single-access RAM. To ascertain the exact size for a given device, see the device-specific memory map figures in Section 2.2. This block is mapped to both program and data space. Block L0 is 2K in size and is dual mapped to both program and data space. Blocks L1 and L2 are both 1K in size, and together with L0, are shared with the CLA which can ultilize these blocks for its data space. Block L3 is 4K in size and is shared with the CLA which can ultilize this block for its program space. DPSARAM refers to the dual-port configuration of these blocks. 2.3.9 Boot ROM The Boot ROM is factory-programmed with boot-loading software. Boot-mode signals are provided to tell the bootloader software what boot mode to use on power up. The user can select to boot normally or to download new software from an external connection or to select boot software that is programmed in the internal Flash/ROM. The Boot ROM also contains standard tables, such as SIN/COS waveforms, for use in math-related algorithms. Table 2-6. Boot Mode Selection MODE GPIO37/TDO GPIO34/COMP2OUT/ TRST MODE COMP3OUT 3 1 1 0 GetMode 2 1 0 0 Wait (see Section 2.3.10 for description) 1 0 1 0 SCI 0 0 0 0 Parallel IO EMU x x 1 Emulation Boot 2.3.9.1 Emulation Boot When the emulator is connected, the GPIO37/TDO pin cannot be used for boot mode selection. In this case, the boot ROM detects that an emulator is connected and uses the contents of two reserved SARAM locations in the PIE vector table to determine the boot mode. If the content of either location is invalid, then the Wait boot option is used. All boot mode options can be accessed in emulation boot. 2.3.9.2 GetMode The default behavior of the GetMode option is to boot to flash. This behavior can be changed to another boot option by programming two locations in the OTP. If the content of either OTP location is invalid, then boot to flash is used. One of the following loaders can be specified: SCI, SPI, I2C, CAN, or OTP.

The dual-zone feature enables the user to co-develop application software with a third-party or sub-contractor by preventing visibility into each other's software IP. The security features a 128-bit password (hardcoded for 16 wait states) for each zone, which the user programs into the USER-OTP. Each zone has its own dedicated USER-OTP, which needs to be programmed by the user with the required security settings, including the 128-bit password. Since OTP cannot be erased, in order to provide the user with the flexibility of changing security-related settings and passwords multiple times, a 32-bit link pointer is stored at the beginning of each USER-OTP. Considering the fact that user can only flip a ‘1’ in USER-OTP to ‘0’, the most significant bit position in the link pointer, programmed as 0, defines the USER-OTP region (zone-select) for each zone in which security-related settings and passwords are stored.

Individual flash sectors and SARAM blocks can be attached to any of the secure zone at start-up time. Secure ROM and the CLA are always attached to Z1. Resources attached to (owned by) one zone do not have any access to code running in the other zone when it is secured. Individual flash sectors, as well as SARAM blocks, can be further protected by enabling the EXEONLY protection. EXEONLY flash sectors or SARAM blocks do not have READ/WRITE access. Only code execution is allowed from such memory blocks.

To enable access to the secure blocks of a particular zone, the user must write a 128-bit value in the zone’s CSMKEY registers that matches the values stored in the password locations in USER-OTP. If the 128 bits of the password locations in USER-OTP of a particular zone are all ones (un-programmed), then the security for that zone gets UNLOCKED as soon as a dummy read is done to the password locations in USER-OTP (the value in the CSMKEY register becomes "Don’t care" in this case). In addition to the DCSM, the Emulation Code Security Logic (ECSL) has been implemented for each zone to prevent unauthorized users from stepping through secure code. A halt inside secure code will trip the ECSL and break the emulation connection. To allow emulation of secure code while maintaining DCSM protection against secure memory reads, the user must write the lower 64 bits of the USER-OTP password into the zone's CSMKEY register to disable the ECSL. Note that dummy reads of all 128 bits of the password for that particular zone in USER-OTP must still be performed. If the lower 64 bits of the password locations of a particular zone are all zeros, then the ECSL for that zone gets disabled as soon as a dummy read is done to the password locations in USER-OTP (the value in the CSMKEY register becomes "Don’t care" in this case). When initially debugging a device with the password locations in OTP (that is, secured), the CPU will start running and may execute an instruction that performs an access to ECSL-protected area. If the CPU execution is halted when the program counter belongs to the secure code region, the ECSL will trip and cause the emulator connection to be cut. The solution is to use the Wait boot option. The Wait boot option will sit in a loop around a software breakpoint to allow an emulator to be connected without tripping security. The user can then exit this mode once the emulator is connected by using one of the emulation boot options as described in the Boot ROM chapter of the TMS320x2805x Piccolo Technical Reference Manual (literature number SPRUHE5). 2805x devices do not support hardware wait-in-reset mode. To prevent reverse-engineering of the code in secure zone, unauthorized users are prevented from looking at the CPU registers in the CCS Expressions Window. The values in the Expressions Window for all of these registers, except for PC and some status bits, display false values when code is running from a secure zone. This feature gets disabled if the zone is unlocked. NOTE • The USER-OTP contains security-related settings for their respective zone. Execution is not allowed from the USER-OTP; therefore, the user should not keep any code/data in this region. • The 128-bit password must not be programmed to zeros. Doing so would permanently lock the device. • The user must try not to write into the CPU registers through the debugger watch window when code is running/halted from/inside secure zone. This may corrupt the execution of the actual program. 20 Device Overview Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 Disclaimer Dual Code Security Module Disclaimer THE DUAL CODE SECURITY MODULE (DCSM) INCLUDED ON THIS DEVICE WAS DESIGNED TO PASSWORD PROTECT THE DATA STORED IN THE ASSOCIATED MEMORY (EITHER ROM OR FLASH) AND IS WARRANTED BY TEXAS INSTRUMENTS (TI), IN ACCORDANCE WITH ITS STANDARD TERMS AND CONDITIONS, TO CONFORM TO TI'S PUBLISHED SPECIFICATIONS FOR THE WARRANTY PERIOD APPLICABLE FOR THIS DEVICE.

The PIE block can support up to 96 peripheral interrupts. On the F2805x devices, 54 of the possible 96 interrupts are used by peripherals. The 96 interrupts are grouped into blocks of 8 and each group is fed into 1 of 12 CPU interrupt lines (INT1 to INT12). Each of the 96 interrupts is supported by its own vector stored in a dedicated RAM block that can be overwritten by the user. The vector is automatically fetched by the CPU on servicing the interrupt. Eight CPU clock cycles are needed to fetch the vector and save critical CPU registers. Hence the CPU can quickly respond to interrupt events. Prioritization of interrupts is controlled in hardware and software. Each individual interrupt can be enabled or disabled within the PIE block.

Each of the interrupts can be selected for negative, positive, or both negative and positive edge triggering and can also be enabled or disabled. These interrupts also contain a 16-bit free running up counter, which is reset to zero when a valid interrupt edge is detected. This counter can be used to accurately time stamp the interrupt. There are no dedicated pins for the external interrupts. XINT1, XINT2, and XINT3 interrupts can accept inputs from GPIO0–GPIO31 pins. 2.3.13 Internal Zero-Pin Oscillators, Oscillator, and PLL The device can be clocked by either of the two internal zero-pin oscillators, an external oscillator, or by a crystal attached to the on-chip oscillator circuit. A PLL is provided supporting up to 12 input-clock-scaling ratios. The PLL ratios can be changed on-the-fly in software, enabling the user to scale back on operating frequency if lower power operation is desired. Refer to Section 5.2 for timing details. The PLL block can be set in bypass mode. 2.3.14 Watchdog Each device contains two watchdogs: CPU-Watchdog that monitors the core and NMI-Watchdog that is a missing clock-detect circuit. The user software must regularly reset the CPU-watchdog counter within a certain time frame; otherwise, the CPU-watchdog generates a reset to the processor. The CPU-watchdog can be disabled if necessary. The NMI-Watchdog engages only in case of a clock failure and can either generate an interrupt or a device reset. 2.3.15 Peripheral Clocking The clocks to each individual peripheral can be enabled or disabled to reduce power consumption when a peripheral is not in use. Additionally, the system clock to the serial ports (except I2C) can be scaled relative to the CPU clock. 2.3.16 Low-power Modes The devices are full-static CMOS devices. Three low-power modes are provided: IDLE: Place CPU in low-power mode. Peripheral clocks may be turned off selectively and only those peripherals that need to function during IDLE are left operating. An enabled interrupt from an active peripheral or the watchdog timer will wake the processor from IDLE mode. STANDBY: Turns off clock to CPU and peripherals. This mode leaves the oscillator and PLL functional. An external interrupt event will wake the processor and the peripherals. Execution begins on the next valid cycle after detection of the interrupt event HALT: This mode basically shuts down the device and places the device in the lowest possible power consumption mode. If the internal zero-pin oscillators are used as the clock source, the HALT mode turns them off, by default. To keep these oscillators from shutting down, the INTOSCnHALTI bits in CLKCTL register may be used. The zero-pin oscillators may thus be used to clock the CPU-watchdog in this mode. If the on-chip crystal oscillator is used as the clock source, the crystal oscillator is shut down in this mode. A reset or an external signal (through a GPIO pin) or the CPUwatchdog can wake the device from this mode. The CPU clock (OSCCLK) and WDCLK should be from the same clock source before attempting to put the device into HALT or STANDBY. 22 Device Overview Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 2.3.17 Peripheral Frames 0, 1, 2, 3 (PFn) The device segregates peripherals into four sections.

This muxing enables the user to use a pin as GPIO if the peripheral signal or function is not used. On reset, GPIO pins are configured as inputs. The user can individually program each pin for GPIO mode or peripheral signal mode. For specific inputs, the user can also select the number of input qualification cycles. This selection is to filter unwanted noise glitches. The GPIO signals can also be used to bring the device out of specific low-power modes.

The timers have a 32-bit count-down register, which generates an interrupt when the counter reaches zero. The counter is decremented at the CPU clock speed divided by the prescale value setting. When the counter reaches zero, the counter is automatically reloaded with a 32-bit period value. CPU-Timer 0 is for general use and is connected to the PIE block. CPU-Timer 1 is also for general use and can be connected to INT13 of the CPU. CPU-Timer 2 is reserved for DSP/BIOS. CPU-Timer 2 is connected to INT14 of the CPU. If DSP/BIOS is not being used, CPU-Timer 2 is available for general use. CPU-Timer 2 can be clocked by any one of the following: • SYSCLKOUT (default) • Internal zero-pin oscillator 1 (INTOSC1) • Internal zero-pin oscillator 2 (INTSOC2) • External clock source 2.3.20 Control Peripherals The devices support the following peripherals that are used for embedded control and communication: ePWM: The enhanced PWM peripheral supports independent/complementary PWM generation, adjustable dead-band generation for leading/trailing edges, latched/cycle-by-cycle trip mechanism. The type 1 module found on 2805x devices also supports increased dead-band resolution, enhanced SOC and interrupt generation, and advanced triggering including trip functions based on comparator outputs. eCAP: The enhanced capture peripheral uses a 32-bit time base and registers up to four programmable events in continuous/one-shot capture modes. This peripheral can also be configured to generate an auxiliary PWM signal. eQEP: The enhanced QEP peripheral uses a 32-bit position counter, supports low-speed measurement using capture unit and high-speed measurement using a 32-bit unit timer. This peripheral has a watchdog timer to detect motor stall and input error detection logic to identify simultaneous edge transition in QEP signals. ADC: The ADC block is a 12-bit converter. The ADC has up to 16 single-ended channels pinned out, depending on the device. The ADC also contains two sample-and-hold units for simultaneous sampling. Comparator and Each comparator block consists of one analog comparator along with an Digital Filter internal 6-bit reference for supplying one input of the comparator. The Subsystems: comparator output signal filtering is achieved using the Digital Filter present on each input line and qualifies the output of the COMP/DAC subsystem. The filtered or unfiltered output of the COMP/DAC subsystem can be configured to be an input to the Digital Compare submodule of the ePWM peripheral. There is also a configurable option to bring the output of the COMP/DAC subsystem onto the GPIO’s. 24 Device Overview Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 2.3.21 Serial Port Peripherals The devices support the following serial communication peripherals: SPI: The SPI is a high-speed, synchronous serial I/O port that allows a serial bit stream of programmed length (one to sixteen bits) to be shifted into and out of the device at a programmable bit-transfer rate. Normally, the SPI is used for communications between the MCU and external peripherals or another processor. Typical applications include external I/O or peripheral expansion through devices such as shift registers, display drivers, and ADCs. Multi-device communications are supported by the master/slave operation of the SPI. The SPI contains a 4-level receive and transmit FIFO for reducing interrupt servicing overhead. SCI: The serial communications interface is a two-wire asynchronous serial port, commonly known as UART. The SCI contains a 4-level receive and transmit FIFO for reducing interrupt servicing overhead. I2C: The inter-integrated circuit (I2C) module provides an interface between an MCU and other devices compliant with Philips Semiconductors Inter-IC bus (I2C-bus) specification version 2.1 and connected by way of an I2C-bus. External components attached to this 2-wire serial bus can transmit and receive up to 8-bit data to and from the MCU through the I2C module. The I2C contains a 4-level receive and transmit FIFO for reducing interrupt servicing overhead. eCAN: The eCAN is the enhanced version of the CAN peripheral. The eCAN supports 32 mailboxes, time stamping of messages, and is CAN 2.0B-compliant.

This feature eliminates the cost and space of a second external regulator on an application board. Additionally, internal power-on reset (POR) and brown-out reset (BOR) circuits monitor both the VDD and VDDIO rails during power-up and run mode. 2.6.1 On-chip Voltage Regulator (VREG) A linear regulator generates the core voltage (VDD) from the VDDIO supply. Therefore, although capacitors are required on each VDD pin to stabilize the generated voltage, power need not be supplied to these pins to operate the device. Conversely, the VREG can be disabled, should power or redundancy be the primary concern of the application. 2.6.1.1 Using the On-chip VREG To utilize the on-chip VREG, the VREGENZ pin should be tied low and the appropriate recommended operating voltage should be supplied to the VDDIO and VDDA pins. In this case, the VDD voltage needed by the core logic will be generated by the VREG. Each VDD pin requires on the order of 1.2 μF (minimum) capacitance for proper regulation of the VREG. These capacitors should be located as close as possible to the VDD pins. 2.6.1.2 Disabling the On-chip VREG To conserve power, it is also possible to disable the on-chip VREG and supply the core logic voltage to the VDD pins with a more efficient external regulator. To enable this option, the VREGENZ pin must be tied high. 30 Device Overview Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION I/O Pin In Out DIR (0 = Input, 1 = Output) (Force Hi-Z When High) SYSRS C28x Core Sync RS XRS PLL + Clocking Logic MCLKRS VREGHALT Deglitch Filter On-Chip Voltage Regulator (VREG) VREGENZ POR/BOR Generating Module XRS Pin SYSCLKOUT WDRST (A) JTAG TCK Detect Logic PBRS (B) Internal Weak PU TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 2.6.2 On-chip Power-On Reset (POR) and Brown-Out Reset (BOR) Circuit The purpose of the POR is to create a clean reset throughout the device during the entire power-up procedure. The trip point is a looser, lower trip point than the BOR, which watches for dips in the VDD or VDDIO rail during device operation. The POR function is present on both VDD and VDDIO rails at all times. After initial device power-up, the BOR function is present on VDDIO at all times, and on VDD when the internal VREG is enabled (VREGENZ pin is tied low). Both functions tie the XRS pin low when one of the voltages is below their respective trip point. Additionally, when the internal voltage regulator is enabled, an over-voltage protection circuit will tie XRS low if the VDD rail rises above its trip point. See Section 4.3 for the various trip points as well as the delay time for the device to release the XRS pin after the undervoltage or over-voltage condition is removed. Figure 2-5 shows the VREG, POR, and BOR. To disable both the VDD and VDDIO BOR functions, a bit is provided in the BORCFG register.

By default both oscillators are turned on at power up, and internal oscillator 1 is the default clock source at this time. For power savings, unused oscillators may be powered down by the user. The center frequency of these oscillators is determined by their respective oscillator trim registers, written to in the calibration routine as part of the boot ROM execution. See Section 5.2.1 for more information on these oscillators. 2.7.2 Crystal Oscillator Option The typical specifications for the external quartz crystal (fundamental mode, parallel resonant) are listed in Table 2-19.

TI recommends that customers have the resonator/crystal vendor characterize the operation of their device with the MCU chip. The resonator/crystal vendor has the equipment and expertise to tune the tank circuit. The vendor can also advise the customer regarding the proper tank component values that will produce proper start up and stability over the entire operating range. Figure 2-9.

This module provides all the necessary clocking signals for the device, as well as control for low-power mode entry. The PLL has a 4-bit ratio control PLLCR[DIV] to select different CPU clock rates. The watchdog module should be disabled before writing to the PLLCR register. The watchdog module can be re-enabled (if need be) after the PLL module has stabilized, which takes 1 ms. The input clock and PLLCR[DIV] bits should be chosen in such a way that the output frequency of the PLL (VCOCLK) is at least 50 MHz. Table 2-20.

A reset issued by the debugger or the missing clock detect logic has no effect. (2) This register is EALLOW protected. See the System Control and Interrupts chapter of the TMS320x2805x Piccolo Technical Reference Manual (literature number SPRUHE5) for more information. (3) By default, PLLSTS[DIVSEL] is configured for /4. (The boot ROM changes the PLLSTS[DIVSEL] configuration to /1.) PLLSTS[DIVSEL] must be 0 before writing to the PLLCR and should be changed only after PLLSTS[PLLLOCKS] = 1. Table 2-21.

INTOSC1 can provide the clock for the Watchdog block, core and CPU-Timer 2. • INTOSC2 (Internal Zero-pin Oscillator 2): INTOSC2 is the on-chip internal oscillator 2. INTOSC2 can provide the clock for the Watchdog block, core and CPU-Timer 2. Both INTOSC1 and INTOSC2 can be independently chosen for the Watchdog block, core and CPU-Timer 2. • Crystal/Resonator Operation: The on-chip (crystal) oscillator enables the use of an external crystal/resonator attached to the device to provide the time base. The crystal/resonator is connected to the X1/X2 pins. Some devices may not have the X1/X2 pins. See Table 3-1 for details. • External Clock Source Operation: If the on-chip (crystal) oscillator is not used, this mode allows the on-chip (crystal) oscillator to be bypassed. The device clocks are generated from an external clock source input on the XCLKIN pin. Note that the XCLKIN is multiplexed with GPIO19 or GPIO38 pin. The XCLKIN input can be selected as GPIO19 or GPIO38 via the XCLKINSEL bit in XCLK register. The CLKCTL[XCLKINOFF] bit disables this clock input (forced low). If the clock source is not used or the respective pins are used as GPIOs, the user should disable at boot time. Before changing clock sources, ensure that the target clock is present. If a clock is not present, then that clock source must be disabled (using the CLKCTL register) before switching clocks. Table 2-22. Possible PLL Configuration Modes PLL MODE REMARKS PLLSTS[DIVSEL] CLKIN AND SYSCLKOUT Invoked by the user setting the PLLOFF bit in the PLLSTS register. The PLL block is disabled in this mode. The PLL block being disabled can be useful in reducing 0, 1 OSCCLK/4 PLL Off system noise and for low-power operation. The PLLCR register must first be set to 2 OSCCLK/2 0x0000 (PLL Bypass) before entering this mode. The CPU clock (CLKIN) is 3 OSCCLK/1 derived directly from the input clock on either X1/X2, X1 or XCLKIN. PLL Bypass is the default PLL configuration upon power-up or after an external 0, 1 OSCCLK/4 PLL Bypass reset (XRS). This mode is selected when the PLLCR register is set to 0x0000 or 2 OSCCLK/2 while the PLL locks to a new frequency after the PLLCR register has been 3 OSCCLK/1 modified. In this mode, the PLL itself is bypassed but the PLL is not turned off. Achieved by writing a non-zero value n into the PLLCR register. Upon writing to the 0, 1 OSCCLK * n/4 PLL Enable PLLCR the device will switch to PLL Bypass mode until the PLL locks. 2 OSCCLK * n/2 3 OSCCLK * n/1 2.7.4 Loss of Input Clock (NMI Watchdog Function) The 2805x devices may be clocked from either one of the internal zero-pin oscillators (INTOSC1 or INTOSC2), the on-chip crystal oscillator, or from an external clock input. Regardless of the clock source, in PLL-enabled and PLL-bypass mode, if the input clock to the PLL vanishes, the PLL will issue a limpmode clock at its output. This limp-mode clock continues to clock the CPU and peripherals at a typical frequency of 1–5 MHz. When the limp mode is activated, a CLOCKFAIL signal is generated that is latched as an NMI interrupt. Depending on how the NMIRESETSEL bit has been configured, a reset to the device can be fired immediately or the NMI watchdog counter can issue a reset when the counter overflows. In addition to this action, the Missing Clock Status (MCLKSTS) bit is set. The NMI interrupt could be used by the application to detect the input clock failure and initiate necessary corrective action such as switching over to an alternative clock source (if available) or initiate a shut-down procedure for the system. If the software does not respond to the clock-fail condition, the NMI watchdog triggers a reset after a preprogrammed time interval. Figure 2-10 shows the interrupt mechanisms involved.

NMI-watchdog 2.7.5 CPU-Watchdog Module The CPU-watchdog module on the 2805x device is similar to the one used on the 281x, 280x, and 283xx devices. This module generates an output pulse, 512 oscillator clocks wide (OSCCLK), whenever the 8-bit watchdog up counter has reached its maximum value. To prevent this occurrence, the user must disable the counter or the software must periodically write a 0x55 + 0xAA sequence into the watchdog key register that resets the watchdog counter. Figure 2-11 shows the various functional blocks within the watchdog module. Normally, when the input clocks are present, the CPU-watchdog counter decrements to initiate a CPUwatchdog reset or WDINT interrupt. However, when the external input clock fails, the CPU-watchdog counter stops decrementing (that is, the watchdog counter does not change with the limp-mode clock). NOTE The CPU-watchdog is different from the NMI watchdog. The CPU-watchdog is the legacy watchdog that is present in all 28x devices. NOTE Applications in which the correct CPU operating frequency is absolutely critical should implement a mechanism by which the MCU will be held in reset, should the input clocks ever fail. For example, an R-C circuit may be used to trigger the XRS pin of the MCU, should the capacitor ever get fully charged. An I/O pin may be used to discharge the capacitor on a periodic basis to prevent the capacitor from getting fully charged. Such a circuit would also help in detecting failure of the flash memory. 38 Device Overview Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION /512 WDCLK WDCR (WDPS[2:0]) WDCLK WDCNTR(7:0) WDKEY(7:0) Good Key 1 0 1 WDCR (WDCHK[2:0]) Bad WDCHK Key WDCR (WDDIS) Clear Counter SCSR (WDENINT) Watchdog Prescaler Generate Output Pulse (512 OSCCLKs) 8-Bit Watchdog Counter CLR WDRST WDINT Watchdog 55 + AA Key Detector XRS Core-reset WDRST(A) Internal Pullup TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 A. The WDRST signal is driven low for 512 OSCCLK cycles. Figure 2-11. CPU-watchdog Module The WDINT signal enables the watchdog to be used as a wakeup from IDLE/STANDBY mode. In STANDBY mode, all peripherals are turned off on the device. The only peripheral that remains functional is the CPU-watchdog. This module will run off OSCCLK. The WDINT signal is fed to the LPM block so that the signal can wake the device from STANDBY (if enabled). See Section 2.8, Low-power Modes Block, for more details. In IDLE mode, the WDINT signal can generate an interrupt to the CPU, via the PIE, to take the CPU out of IDLE mode. In HALT mode, the CPU-watchdog can be used to wake up the device through a device reset.

(1) The Exit column lists which signals or under what conditions the low power mode is exited. A low signal, on any of the signals, exits the low power condition. This signal must be kept low long enough for an interrupt to be recognized by the device. Otherwise, the low-power mode will not be exited and the device will go back into the indicated low power mode. (2) The JTAG port can still function even if the CPU clock (CLKIN) is turned off. (3) The WDCLK must be active for the device to go into HALT mode. The various low-power modes operate as follows: IDLE Mode: This mode is exited by any enabled interrupt that is recognized by the processor. The LPM block performs no tasks during this mode as long as the LPMCR0(LPM) bits are set to 0,0. STANDBY Mode: Any GPIO port A signal (GPIO[31:0]) can wake the device from STANDBY mode. The user must select which signals will wake the device in the GPIOLPMSEL register. The selected signals are also qualified by the OSCCLK before waking the device. The number of OSCCLKs is specified in the LPMCR0 register. HALT Mode: CPU-watchdog, XRS, and any GPIO port A signal (GPIO[31:0]) can wake the device from HALT mode. The user selects the signal in the GPIOLPMSEL register. NOTE The low-power modes do not affect the state of the output pins (PWM pins included). They will be in whatever state the code left them in when the IDLE instruction was executed. See the System Control and Interrupts chapter of the TMS320x2805x Piccolo Technical Reference Manual (literature number SPRUHE5) for more details. 2.9 Thermal Design Considerations Based on the end application design and operational profile, the IDD and IDDIO currents could vary. Systems that exceed the recommended maximum power dissipation in the end product may require additional thermal enhancements. Ambient temperature (TA) varies with the end application and product design. The critical factor that affects reliability and functionality is TJ, the junction temperature, not the ambient temperature. Hence, care should be taken to keep TJ within the specified limits. Tcase should be measured to estimate the operating junction temperature TJ. Tcase is normally measured at the center of the package top-side surface. The thermal application reports IC Package Thermal Metrics (literature number SPRA953) and Reliability Data for TMS320LF24xx and TMS320F28xx Devices (literature number SPRA963) help to understand the thermal metrics and definitions. 40 Device Overview Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION 20 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 41 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 21 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 80 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 VSSA VSS VDDIO GPIO26/SCIRXDC TEST2 GPIO9/EPWM5B/SCITXDB GPIO30/CANRXA/SCIRXDB/EPWM7A GPIO31/CANTXA/SCITXDB/EPWM7B GPIO27/SCITXDC PFCGND ADCINB7 (op-amp) ADCINB0 ADCINB6 (op-amp) ADCINB5 M2GND ADCINB4 (op-amp) ADCINB3 ADCINA7 ADCINA6 (op-amp) VREFLO GPIO23/EQEP1I/SCIRXDB GPIO11/EPWM6B/SCIRXDB GPIO5/EPWM3B/SPISIMOA/ECAP1 GPIO4/EPWM3A GPIO40/EPWM7A GPIO10/EPWM6A/ADCSOCBO GPIO3/EPWM2B/SPISOMIA/CTRIPM2OUT (COMP2OUT) GPIO2/EPWM2A GPIO1/EPWM1B/CTRIPM1OUT (COMP1OUT) GPIO0/EPWM1A VDDIO VREGENZ VSS VDD GPIO34/CTRIPM2OUT (COMP2OUT)/CTRIPPFCOUT (COMP3OUT) GPIO15/TZ1/CTRIPM1OUT/SCIRXDB GPIO13/TZ2/CTRIPM2OUT GPIO14/TZ3/CTRIPPFCOUT/SCITXDB GPIO20/EQEP1A/EPWM7A/CTRIPM1OUT (COMP1OUT) GPIO21/EQEP1B/EPWM7B/CTRIPM2OUT (COMP2OUT) VDDA GPIO22/EQEP1S/SCITXDB XRS GPIO32/SDAA/EPWMSYNCI/EQEP1S GPIO33/SCLA/EPWMSYNCO/EQEP1I GPIO24/ECAP1/EPWM7A GPIO42/EPWM7B/SCITXDC/CTRIPM1OUT (COMP1OUT) VDD VSS TRST ADCBGOUT/ADCINA4 ADCINA5 ADCINA3 (op-amp) ADCINA2 ADCINA1 (op-amp) M1GND ADCINB2 ADCINB1 (op-amp) ADCINA0/VREFOUT VREFHI GPIO29/SCITXDA/SCLA/ /CTRIPPFCOUTTZ3 GPIO36/TMS GPIO35/TDI GPIO37/TDO GPIO38/TCK/XCLKIN GPIO39/SCIRXDC/CTRIPPFCOUT GPIO19/XCLKIN/ /SCIRXDB/ECAP1SPISTEA VDD VSS X1 X2 GPIO6/EPWM4A/EPWMSYNCI/EPWMSYNCO GPIO7/EPWM4B/SCIRXDA GPIO16/SPISIMOA/EQEP1S/ /CTRIPM2OUTTZ2 GPIO12/ /CTRIPM1OUT/SCITXDATZ1 GPIO25 GPIO8/EPWM5A/ADCSOCAO GPIO17/SPISOMIA/EQEP1I/ /CTRIPPFCOUTTZ3 GPIO18/SPICLKA/SCITXDB/XCLKOUT GPIO28/SCIRXDA/SDAA/TZ2/CTRIPM2OUT TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 3 Device Pins 3.1 Pin Assignments Figure 3-1 shows the 80-pin PN Low-Profile Quad Flatpack (LQFP) pin assignments.

With the exception of the JTAG pins, the GPIO function is the default at reset, unless otherwise mentioned. The peripheral signals that are listed under them are alternate functions. Some peripheral functions may not be available in all devices. See Table 2-1 for details. Inputs are not 5-V tolerant. All GPIO pins are I/O/Z and have an internal pullup, which can be selectively enabled or disabled on a per-pin basis. This feature only applies to the GPIO pins. The pullups on the PWM pins are not enabled at reset. The pullups on other GPIO pins are enabled upon reset. NOTE: When the on-chip VREG is used, the GPIO19, GPIO34, GPIO35, GPIO36, GPIO37, and GPIO38 pins could glitch during power up. If this behavior is unacceptable in an application, 1.8 V could be supplied externally. There is no power-sequencing requirement when using an external 1.8-V supply. However, if the 3.3-V transistors in the level-shifting output buffers of the I/O pins are powered prior to the 1.9-V transistors, it is possible for the output buffers to turn on, causing a glitch to occur on the pin during power up. To avoid this behavior, power the VDD pins prior to or simultaneously with the VDDIO pins, ensuring that the VDD pins have reached 0.7 V before the VDDIO pins reach 0.7 V. Table 3-1. Terminal Functions(1) TERMINAL PN I/O/Z DESCRIPTION NAME PIN NO. JTAG JTAG test reset with internal pulldown. TRST, when driven high, gives the scan system control of the operations of the device. If this signal is not connected or driven low, the device operates in its functional mode, and the test reset signals are ignored. NOTE: TRST is an active high test pin and must be maintained low at all times during normal device operation. TRST 9 I An external pull-down resistor is required on this pin. The value of this resistor should be based on drive strength of the debugger pods applicable to the design. A 2.2-kΩ resistor generally offers adequate protection. Since the value of the resistor is application-specific, TI recommends that each target board be validated for proper operation of the debugger and the application. (↓) TCK See I See GPIO38.

XCLKOUT is either the same See frequency, one-half the frequency, or one-fourth the frequency of SYSCLKOUT. The value of XCLKOUT GPIO18 O/Z XCLKOUT is controlled by bits 1:0 (XCLKOUTDIV) in the XCLK register. At reset, XCLKOUT = SYSCLKOUT/4. The XCLKOUT signal can be turned off by setting XCLKOUTDIV to 3. The mux control for GPIO18 must also be set to XCLKOUT for this signal to propogate to the pin. See GPIO19 and GPIO38. External oscillator input. Pin source for the clock is controlled by the XCLKINSEL bit in the XCLK register, GPIO38 is the default selection. This pin feeds a clock from an external 3.3-V oscillator. In this case, the X1 pin, if available, must be tied to See GND and the on-chip crystal oscillator must be disabled via bit 14 in the CLKCTL register. If a XCLKIN GPIO19 I crystal/resonator is used, the XCLKIN path must be disabled by bit 13 in the CLKCTL register. and NOTE: Designs that use the GPIO38/TCK/XCLKIN pin to supply an external clock for normal GPIO38 device operation may need to incorporate some hooks to disable this path during debug using the JTAG connector. This action is to prevent contention with the TCK signal, which is active during JTAG debug sessions. The zero-pin internal oscillators may be used during this time to clock the device. On-chip crystal-oscillator input. To use this oscillator, a quartz crystal or a ceramic resonator X1 52 I must be connected across X1 and X2. In this case, the XCLKIN path must be disabled by bit 13 in the CLKCTL register. If this pin is not used, this pin must be tied to GND. (I) X2 51 O On-chip crystal-oscillator output. A quartz crystal or a ceramic resonator must be connected across X1 and X2. If X2 is not used, X2 must be left unconnected. (O) RESET Device Reset (in) and Watchdog Reset (out). The device has a built-in power-on-reset (POR) and brown-out-reset (BOR) circuitry. As such, no external circuitry is needed to generate a reset pulse. During a power-on or brown-out condition, this pin is driven low by the device. See Section 4.3, Electrical Characteristics, for thresholds of the POR/BOR block. This pin is also driven low by the MCU when a watchdog reset occurs. During watchdog reset, the XRS XRS 8 I/O pin is driven low for the watchdog reset duration of 512 OSCCLK cycles. If need be, an external circuitry may also drive this pin to assert a device reset. In this case, TI recommends that this pin be driven by an open-drain device. An R-C circuit must be connected to this pin for noise immunity reasons. Regardless of the source, a device reset causes the device to terminate execution. The program counter points to the address contained at the location 0x3FFFC0. When reset is deactivated, execution begins at the location designated by the program counter. The output buffer of this pin is an open-drain with an internal pullup.

(2) In order to realize the IDDA currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register. (3) The TYP numbers are applicable over room temperature and nominal voltage. (4) The following is done in a loop: • Data is continuously transmitted out of SPI-A, SCI-A, SCI-B, SCI-C, eCAN-A, and I2C-A ports. • The hardware multiplier is exercised. • Watchdog is reset. • ADC is performing continuous conversion. • GPIO17 is toggled. (5) CLA is continuously performing polynomial calculations. (6) For F2805x devices that do not have CLA, subtract the IDD current number for CLA (see Table 4-2) from the IDD (VREG disabled)/IDDIO (VREG enabled) current numbers shown in Table 4-1 for operational mode. (7) If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the on-chip crystal oscillator. NOTE The peripheral-I/O multiplexing implemented in the device prevents all available peripherals from being used at the same time because more than one peripheral function may share an I/O pin. It is, however, possible to turn on the clocks to all the peripherals at the same time, although such a configuration is not useful. If the clocks to all the peripherals are turned on at the same time, the current drawn by the device will be more than the numbers specified in the current consumption tables. 52 Device Operating Conditions Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 4.4.1 Reducing Current Consumption The 2805x devices incorporate a method to reduce the device current consumption. Since each peripheral unit has an individual clock-enable bit, significant reduction in current consumption can be achieved by turning off the clock to any peripheral module that is not used in a given application. Furthermore, any one of the three low-power modes could be taken advantage of to reduce the current consumption even further. Table 4-2 indicates the typical reduction in current consumption achieved by turning off the clocks. Table 4-2. Typical Current Consumption by Various Peripherals (at 60 MHz)(1) PERIPHERAL IDD CURRENT MODULE(2) REDUCTION (mA) ADC 2(3) I2C 3 ePWM 2 eCAP 2 eQEP 2 SCI 2 SPI 2 COMP/DAC 1 PGA 2 CPU-TIMER 1 Internal zero-pin oscillator 0.5 CAN 2.5 CLA 20 (1) All peripheral clocks (except CPU Timer clock) are disabled upon reset. Writing to or reading from peripheral registers is possible only after the peripheral clocks are turned on. (2) For peripherals with multiple instances, the current quoted is per module. For example, the 2 mA value quoted for ePWM is for one ePWM module. (3) This number represents the current drawn by the digital portion of the ADC module. Turning off the clock to the ADC module results in the elimination of the current drawn by the analog portion of the ADC (IDDA) as well. NOTE IDDIO current consumption is reduced by 15 mA (typical) when XCLKOUT is turned off. NOTE The baseline IDD current (current when the core is executing a dummy loop with no peripherals enabled) is 40 mA, typical. To arrive at the IDD current for a given application, the current-drawn by the peripherals (enabled by that application) must be added to the baseline IDD current. Following are other methods to reduce power consumption further: • The flash module may be powered down if code is run off SARAM. This method results in a current reduction of 18 mA (typical) in the VDD rail and 13 mA (typical) in the VDDIO rail. • Savings in IDDIO may be realized by disabling the pullups on pins that assume an output function.

No voltage larger than a diode drop (0.7 V) above VDDIO should be applied to any digital pin (for analog pins, this value is 0.7 V above VDDA) prior to powering up the device. Voltages applied to pins on an unpowered device can bias internal p-n junctions in unintended ways and produce unpredictable results. A. Upon power up, SYSCLKOUT is OSCCLK/4. Since the XCLKOUTDIV bits in the XCLK register come up with a reset state of 0, SYSCLKOUT is further divided by 4 before SYSCLKOUT appears at XCLKOUT. XCLKOUT = OSCCLK/16 during this phase. B. Boot ROM configures the DIVSEL bits for /1 operation. XCLKOUT = OSCCLK/4 during this phase. Note that XCLKOUT will not be visible at the pin until explicitly configured by user code. C. After reset, the boot ROM code samples Boot Mode pins. Based on the status of the Boot Mode pin, the boot code branches to destination memory or boot code function. If boot ROM code executes after power-on conditions (in debugger environment), the boot code execution time is based on the current SYSCLKOUT speed. The SYSCLKOUT will be based on user environment and could be with or without PLL enabled. D. Using the XRS pin is optional due to the on-chip power-on reset (POR) circuitry. E. The internal pullup or pulldown will take effect when BOR is driven high. Figure 5-1.

In the first phase, PLLCR = 0x0004 and SYSCLKOUT = OSCCLK x 2. The PLLCR is then written with 0x0008. Right after the PLLCR register is written, the PLL lock-up phase begins. During this phase, SYSCLKOUT = OSCCLK/2. After the PLL lock-up is complete, SYSCLKOUT reflects the new operating frequency, OSCCLK x 4. Figure 5-3.

In total, 12 CPU interrupt groups, with 8 interrupts per group equals 96 possible interrupts. Table 5-9 shows the interrupts used by 2805x devices. The TRAP #VectorNumber instruction transfers program control to the interrupt service routine corresponding to the vector specified. TRAP #0 attempts to transfer program control to the address pointed to by the reset vector. The PIE vector table does not, however, include a reset vector. Therefore, TRAP #0 should not be used when the PIE is enabled. Doing so will result in undefined behavior. When the PIE is enabled, TRAP #1 through TRAP #12 will transfer program control to the interrupt service routine corresponding to the first vector within the PIE group. For example: TRAP #1 fetches the vector from INT1.1, TRAP #2 fetches the vector from INT2.1, and so forth. Figure 5-7.

These interrupts can be used as software interrupts if they are enabled at the PIEIFRx level, provided none of the interrupts within the group is being used by a peripheral. Otherwise, interrupts coming in from peripherals may be lost by accidentally clearing their flag while modifying the PIEIFR. To summarize, there are two safe cases when the reserved interrupts could be used as software interrupts: • No peripheral within the group is asserting interrupts. • No peripheral interrupts are assigned to the group (for example, PIE group 7).

The signal combinations shown in the following timing diagrams may not necessarily represent actual cycles. For actual cycle examples, see the appropriate cycle description section of this document. 6.1.2 Test Load Circuit This test load circuit is used to measure all switching characteristics provided in this document. A. Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin. B. The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects must be taken into account. A transmission line with a delay of 2 ns or longer can be used to produce the desired transmission line effect. The transmission line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns or longer) from the data sheet timing.

Timecritical control loops serviced by the CLA can achieve low ADC sample to output delay. Thus, the CLA enables faster system response and higher frequency control loops. Utilizing the CLA for time-critical tasks frees up the main CPU to perform other system and communication functions concurently. The following is a list of major features of the CLA. • Clocked at the same rate as the main CPU (SYSCLKOUT). • An independent architecture allowing CLA algorithm execution independent of the main C28x CPU. – Complete bus architecture: • Program address bus and program data bus • Data address bus, data read bus, and data write bus – Independent eight-stage pipeline. – 12-bit program counter (MPC) – Four 32-bit result registers (MR0–MR3) – Two 16-bit auxillary registers (MAR0, MAR1) – Status register (MSTF) • Instruction set includes: – IEEE single-precision (32-bit) floating-point math operations – Floating-point math with parallel load or store – Floating-point multiply with parallel add or subtract – 1/X and 1/sqrt(X) estimations – Data type conversions. – Conditional branch and call – Data load and store operations • The CLA program code can consist of up to eight tasks or interrupt service routines. – The start address of each task is specified by the MVECT registers. – No limit on task size as long as the tasks fit within the CLA program memory space. – One task is serviced at a time through to completion. There is no nesting of tasks. – Upon task completion, a task-specific interrupt is flagged within the PIE. – When a task finishes, the next highest-priority pending task is automatically started. • Task trigger mechanisms: – C28x CPU via the IACK instruction – Task1 to Task7: the corresponding ADC, ePWM, eQEP, or eCAP module interrupt. For example: • Task1: ADCINT1 or EPWM1_INT • Task2: ADCINT2 or EPWM2_INT • Task4: ADCINT4 or EPWM4_INT or EQEPx_INT or ECAPx_INT • Task7: ADCINT7 or EPWM7_INT or EQEPx_INT or ECAPx_INT – Task8: ADCINT8 or by CPU Timer 0 or EQEPx_INT or ECAPx_INT • Memory and Shared Peripherals: – Two dedicated message RAMs for communication between the CLA and the main CPU. – The C28x CPU can map CLA program and data memory to the main CPU space or CLA space. – The CLA has direct access to the CLA Data ROM that stores the math tables required by the routines in the CLA Math Library. – The CLA has direct access to the ADC Result registers, comparator and DAC registers, eCAP, eQEP, and ePWM registers.

The sampleand- hold circuits can be sampled simultaneously or sequentially. These, in turn, are fed by a total of up to 16 analog input channels. The converter can be configured to run with an internal bandgap reference to create true-voltage based conversions or with a pair of external voltage references (VREFHI/VREFLO) to create ratiometric-based conversions. Contrary to previous ADC types, this ADC is not sequencer-based. The user can easily create a series of conversions from a single trigger. However, the basic principle of operation is centered around the configurations of individual conversions, called SOCs, or Start-Of-Conversions. Functions of the ADC module include: • 12-bit ADC core with built-in dual sample-and-hold (S/H) • Simultaneous sampling or sequential sampling modes • Full range analog input: 0 V to 3.3 V fixed, or VREFHI/VREFLO ratiometric. The digital value of the input analog voltage is derived by: – Internal Reference (VREFLO = VSSA. VREFHI must not exceed VDDA when using either internal or external reference modes.) – External Reference (VREFHI/VREFLO connected to external references. VREFHI must not exceed VDDA when using either internal or external reference modes.) • Runs at full system clock, no prescaling required • Up to 16-channel, multiplexed inputs • 16 SOCs, configurable for trigger, sample window, and channel • 16 result registers (individually addressable) to store conversion values • Multiple trigger sources – S/W – software immediate start – ePWM 1–7 – GPIO XINT2 – CPU Timer 0, CPU Timer 1, CPU Timer 2 – ADCINT1, ADCINT2 • 9 flexible PIE interrupts, can configure interrupt request after any conversion 72 Peripheral Information and Timings Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 Table 6-3.

ADC Connections ADC Connections if the ADC is Not Used TI recommends that the connections for the analog power pins be kept, even if the ADC is not used. Following is a summary of how the ADC pins should be connected, if the ADC is not used in an application: • VDDA – Connect to VDDIO • VSSA – Connect to VSS • VREFLO – Connect to VSS • ADCINAn, ADCINBn, VREFHI – Connect to VSSA When the ADC module is used in an application, unused ADC input pins should be connected to analog ground (VSSA). When the ADC is not used, be sure that the clock to the ADC module is not turned on to realize power savings. 74 Peripheral Information and Timings Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 6.3.1.2 Analog-to-Digital Converter Electrical Data/Timing Table 6-5.

The point used as zero occurs one-half LSB before the first code transition. The full-scale point is defined as level one-half LSB beyond the last code transition. The deviation is measured from the center of each particular code to the true straight line between these two points. Differential Nonlinearity An ideal ADC exhibits code transitions that are exactly 1 LSB apart. DNL is the deviation from this ideal value. A differential nonlinearity error of less than ±1 LSB ensures no missing codes. Zero Offset Zero error is the difference between the ideal input voltage and the actual input voltage that just causes a transition from an output code of zero to an output code of one. Gain Error The first code transition should occur at an analog value one-half LSB above negative full scale. The last transition should occur at an analog value one and one-half LSB below the nominal full scale. Gain error is the deviation of the actual difference between first and last code transitions and the ideal difference between first and last code transitions. Signal-to-Noise Ratio + Distortion (SINAD) SINAD is the ratio of the rms value of the measured input signal to the rms sum of all other spectral components below the Nyquist frequency, including harmonics but excluding dc. The value for SINAD is expressed in decibels. Effective Number of Bits (ENOB) For a sine wave, SINAD can be expressed in terms of the number of bits. Using the following formula, it is possible to get a measure of performance expressed as N, the effective number of bits. Thus, effective number of bits for a device for sine wave inputs at a given input frequency can be calculated directly from its measured SINAD. Total Harmonic Distortion (THD) THD is the ratio of the rms sum of the first nine harmonic components to the rms value of the measured input signal and is expressed as a percentage or in decibels. Spurious Free Dynamic Range (SFDR) SFDR is the difference in dB between the rms amplitude of the input signal and the peak spurious signal. 82 Peripheral Information and Timings Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 6.3.2 Analog Front End (AFE) 6.3.2.1 Analog Front End Device-Specific Information The Analog Front End (AFE) contains up to seven comparators with up to three integrated Digital-to- Analog Converters (DACs), one VREFOUT-buffered DAC, up to four Programmable Gain Amplifiers (PGAs), and up to four digital filters. Figure 6-11 and Figure 6-12 show the AFE. The comparator output signal filtering is achieved using the Digital Filter present on selective input line and qualifies the output of the COMP/DAC subsystem (see Figure 6-13). The filtered or unfiltered output of the COMP/DAC subsystem can be configured to be an input to the Digital Compare submodule of the ePWM peripheral. Note: The Analog inputs are brought in through the AFE subsystem rather than through an AIO Mux, which is not present.

The SPI is a high-speed, synchronous serial I/O port that allows a serial bit stream of programmed length (one to sixteen bits) to be shifted into and out of the device at a programmable bit-transfer rate. Normally, the SPI is used for communications between the MCU and external peripherals or another processor. Typical applications include external I/O or peripheral expansion through devices such as shift registers, display drivers, and ADCs. Multidevice communications are supported by the master/slave operation of the SPI. The SPI module features include: • Four external pins: – SPISOMI: SPI slave-output/master-input pin – SPISIMO: SPI slave-input/master-output pin – SPISTE: SPI slave transmit-enable pin – SPICLK: SPI serial-clock pin NOTE: All four pins can be used as GPIO if the SPI module is not used. • Two operational modes: master and slave Baud rate: 125 different programmable rates. • Data word length: one to sixteen data bits • Four clocking schemes (controlled by clock polarity and clock phase bits) include: – Falling edge without phase delay: SPICLK active-high. SPI transmits data on the falling edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal. – Falling edge with phase delay: SPICLK active-high. SPI transmits data one half-cycle ahead of the falling edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal. – Rising edge without phase delay: SPICLK inactive-low. SPI transmits data on the rising edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal. – Rising edge with phase delay: SPICLK inactive-low. SPI transmits data one half-cycle ahead of the falling edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal. • Simultaneous receive and transmit operation (transmit function can be disabled in software) • Transmitter and receiver operations are accomplished through either interrupt-driven or polled algorithms. • Nine SPI module control registers: Located in control register frame beginning at address 7040h. NOTE All registers in this module are 16-bit registers that are connected to Peripheral Frame 2. When a register is accessed, the register data is in the lower byte (7–0), and the upper byte (15–8) is read as zeros. Writing to the upper byte has no effect.

Each SCI module supports digital communications between the CPU and other asynchronous peripherals that use the standard non-return-to-zero (NRZ) format. The SCI receiver and transmitter are doublebuffered, and each has its own separate enable and interrupt bits. Both can be operated independently or simultaneously in the full-duplex mode. To ensure data integrity, the SCI checks received data for break detection, parity, overrun, and framing errors. The bit rate is programmable to over 65000 different speeds through a 16-bit baud-select register. Features of each SCI module include: • Two external pins: – SCITXD: SCI transmit-output pin – SCIRXD: SCI receive-input pin NOTE: Both pins can be used as GPIO if not used for SCI. – Baud rate programmable to 64K different rates: • Data-word format – One start bit – Data-word length programmable from one to eight bits – Optional even/odd/no parity bit – One or two stop bits • Four error-detection flags: parity, overrun, framing, and break detection • Two wake-up multiprocessor modes: idle-line and address bit • Half- or full-duplex operation • Double-buffered receive and transmit functions • Transmitter and receiver operations can be accomplished through interrupt-driven or polled algorithms with status flags. – Transmitter: TXRDY flag (transmitter-buffer register is ready to receive another character) and TX EMPTY flag (transmitter-shift register is empty) – Receiver: RXRDY flag (receiver-buffer register is ready to receive another character), BRKDT flag (break condition occurred), and RX ERROR flag (monitoring four interrupt conditions) • Separate enable bits for transmitter and receiver interrupts (except BRKDT) • NRZ (non-return-to-zero) format NOTE All registers in this module are 8-bit registers that are connected to Peripheral Frame 2. When a register is accessed, the register data is in the lower byte (7–0), and the upper byte (15–8) is read as zeros. Writing to the upper byte has no effect.

Figure 6-22 shows how the I2C peripheral module interfaces within the device. The I2C module has the following features: • Compliance with the Philips Semiconductors I2C-bus specification (version 2.1): – Support for 1-bit to 8-bit format transfers – 7-bit and 10-bit addressing modes – General call – START byte mode – Support for multiple master-transmitters and slave-receivers – Support for multiple slave-transmitters and master-receivers – Combined master transmit/receive and receive/transmit mode – Data transfer rate of from 10 kbps up to 400 kbps (I2C Fast-mode rate) • One 4-word receive FIFO and one 4-word transmit FIFO • One interrupt that can be used by the CPU. This interrupt can be generated as a result of one of the following conditions: – Transmit-data ready – Receive-data ready – Register-access ready – No-acknowledgment received – Arbitration lost – Stop condition detected – Addressed as slave • An additional interrupt that can be used by the CPU when in FIFO mode • Module enable/disable capability • Free data format mode Copyright © 2012, Texas Instruments Incorporated Peripheral Information and Timings 107 Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION I2CXSR I2CDXR I2CRSR I2CDRR Clock Synchronizer Prescaler Noise Filters Arbitrator I2C INT Peripheral Bus Interrupt to CPU/PIE SDA SCL Control/Status Registers CPU I2C Module TX FIFO RX FIFO FIFO Interrupt to CPU/PIE TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 SPRS797 –NOVEMBER 2012 www.ti.com A. The I2C registers are accessed at the SYSCLKOUT rate. The internal timing and signal waveforms of the I2C port are also at the SYSCLKOUT rate. B. The clock enable bit (I2CAENCLK) in the PCLKCRO register turns off the clock to the I2C port for low power operation. Upon reset, I2CAENCLK is clear, which indicates the peripheral internal clocks are off. Figure 6-22.

TCK, TDI, TMS and TDO pins are also GPIO pins. The TRST signal selects either JTAG or GPIO operating mode for the pins in Figure 6-28. During emulation/debug, the GPIO function of these pins are not available. If the GPIO38/TCK/XCLKIN pin is used to provide an external clock, an alternate clock source should be used to clock the device during emulation/debug since this pin will be needed for the TCK function. NOTE In 2805x devices, the JTAG pins may also be used as GPIO pins. Care should be taken in the board design to ensure that the circuitry connected to these pins do not affect the emulation capabilities of the JTAG pin function. Any circuitry connected to these pins should not prevent the emulator from driving (or being driven by) the JTAG pins for successful debug. Figure 6-28.

If the distance between the JTAG header and the MCU is greater than 6 inches, the emulation signals must be buffered. If the distance is less than 6 inches, buffering is typically not needed.

Emulator Connection Without Signal Buffering for the MCU NOTE The 2805x devices do not have EMU0/EMU1 pins.

The sampling period specifies a multiple of SYSCLKOUT cycles for sampling the input signal. The sampling window is either 3-samples or 6-samples wide and the output is only changed when ALL samples are the same (all 0s or all 1s) as shown in Figure 6-32 (for 6 sample mode). • No Synchronization (GPxQSEL1/2 = 1,1): This mode is used for peripherals where synchronization is not required (synchronization is performed within the peripheral). Due to the multi-level multiplexing that is required on the device, there may be cases where a peripheral input signal can be mapped to more then one GPIO pin. Also, when an input signal is not selected, the input signal will default to either a 0 or 1 state, depending on the peripheral. 126 Peripheral Information and Timings Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION GPxDAT (read) Input Qualification GPxMUX1/2 High Impedance Output Control GPIOx pin XRS 0 = Input, 1 = Output Low P ower Modes Block GPxDIR (latch) Peripheral 2 Input Peripheral 3 Input Peripheral 1 Output Peripheral 2 Output Peripheral 3 Output Peripheral 1 Output Enable Peripheral 2 Output Enable Peripheral 3 Output Enable 00 01 10 11 00 01 10 11 00 01 10 11 GPxCTRL Peripheral 1 Input GPxPUD N/C LPMCR0 Internal Pullup GPIOLMPSEL GPxQSEL1/2 GPxSET GPxDAT (latch) GPxCLEAR GPxTOGGLE = Default at Reset PIE External Interrupt MUX Asynchronous path Asynchronous path GPIOXINT1SEL GPIOXINT2SEL GPIOXINT3SEL TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 A. x stands for the port, either A or B.

(2) For tw(GPI), pulse width is measured from VIL to VIL for an active low signal and VIH to VIH for an active high signal. A. This glitch will be ignored by the input qualifier. The QUALPRD bit field specifies the qualification sampling period. The QUALPRD bit field value can vary from 00 to 0xFF. If QUALPRD = 00, then the sampling period is 1 SYSCLKOUT cycle. For any other value "n", the qualification sampling period in 2n SYSCLKOUT cycles (that is, at every 2n SYSCLKOUT cycles, the GPIO pin will be sampled). B. The qualification period selected via the GPxCTRL register applies to groups of 8 GPIO pins. C. The qualification block can take either three or six samples. The GPxQSELn Register selects which sample mode is used. D. In the example shown, for the qualifier to detect the change, the input should be stable for 10 SYSCLKOUT cycles or greater. In other words, the inputs should be stable for (5 x QUALPRD x 2) SYSCLKOUT cycles. This condition would ensure 5 sampling periods for detection to occur. Since external signals are driven asynchronously, an 13- SYSCLKOUT-wide pulse ensures reliable recognition. Figure 6-32.

Sampling frequency denotes how often a signal is sampled with respect to SYSCLKOUT. Sampling frequency = SYSCLKOUT/(2 * QUALPRD), if QUALPRD ≠ 0 Sampling frequency = SYSCLKOUT, if QUALPRD = 0 Sampling period = SYSCLKOUT cycle x 2 x QUALPRD, if QUALPRD ≠ 0 In the above equations, SYSCLKOUT cycle indicates the time period of SYSCLKOUT. Sampling period = SYSCLKOUT cycle, if QUALPRD = 0 In a given sampling window, either 3 or 6 samples of the input signal are taken to determine the validity of the signal. The number of samples is determined by the value written to GPxQSELn register. Case 1: Qualification using 3 samples Sampling window width = (SYSCLKOUT cycle x 2 x QUALPRD) x 2, if QUALPRD ≠ 0 Sampling window width = (SYSCLKOUT cycle) x 2, if QUALPRD = 0 Case 2: Qualification using 6 samples Sampling window width = (SYSCLKOUT cycle x 2 x QUALPRD) x 5, if QUALPRD ≠ 0 Sampling window width = (SYSCLKOUT cycle) x 5, if QUALPRD = 0 Figure 6-33.

IDLE instruction is executed to put the device into HALT mode. B. The PLL block responds to the HALT signal. SYSCLKOUT is held for the number of cycles indicated below before oscillator is turned off and the CLKIN to the core is stopped: • 16 cycles, when DIVSEL = 00 or 01 • 32 cycles, when DIVSEL = 10 • 64 cycles, when DIVSEL = 11 This delay enables the CPU pipeline and any other pending operations to flush properly. C. Clocks to the peripherals are turned off and the PLL is shut down. If a quartz crystal or ceramic resonator is used as the clock source, the internal oscillator is shut down as well. The device is now in HALT mode and consumes absolute minimum power. It is possible to keep the zero-pin internal oscillators (INTOSC1 and INTOSC2) and the watchdog alive in HALT mode. Keeping INTOSC1, INTOSC2, and the watchdog alive in HALT mode is done by writing to the appropriate bits in the CLKCTL register. After the IDLE instruction is executed, a delay of 5 OSCCLK cycles (minimum) is needed before the wake-up signal could be asserted. D. When the GPIOn pin (used to bring the device out of HALT) is driven low, the oscillator is turned on and the oscillator wake-up sequence is initiated. The GPIO pin should be driven high only after the oscillator has stabilized, which enables the provision of a clean clock signal during the PLL lock sequence. Since the falling edge of the GPIO pin asynchronously begins the wakeup procedure, care should be taken to maintain a low noise environment prior to entering and during HALT mode. E. The wake-up signal fed to a GPIO pin to wake up the device must meet the minimum pulse width requirement. Furthermore, this signal must be free of glitches. If a noisy signal is fed to a GPIO pin, the wake-up behavior of the device will not be deterministic and the device may not exit low-power mode for subsequent wake-up pulses. F. Once the oscillator has stabilized, the PLL lock sequence is initiated, which takes 1 ms. G. When CLKIN to the core is enabled, the device will respond to the interrupt (if enabled), after a latency. The HALT mode is now exited. H. Normal operation resumes. I.

For information on pricing and availability, contact the nearest TI field sales office or authorized distributor. 7.1.2 Device and Development Support Tool Nomenclature To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all TMS320™ MCU devices and support tools. Each TMS320™ MCU commercial family member has one of three prefixes: TMX, TMP, or TMS (for example, TMX320F28055). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (with TMX for devices and TMDX for tools) through fully qualified production devices and tools (with TMS for devices and TMDS for tools). Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device's electrical specifications TMP Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification TMS Fully qualified production device Support tool development evolutionary flow: TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing TMDS Fully qualified development-support product 136 Device and Documentation Support Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS320F28055 TMS320F28054 TMS320F28053 TMS320F28052 TMS320F28051 TMS320F28050 ADVANCE INFORMATION PREFIX TMX TMX = experimental device TMP = prototype device TMS = qualified device 320 DEVICE FAMILY 320 = TMS320 MCU Family F TECHNOLOGY F = Flash 28055 DEVICE 28055 28054 28053 28052 28051 28050 PN PACKAGE TYPE 80-Pin PN Low-Profile Quad Flatpack (LQFP) TEMPERATURE RANGE T −40°C to 105°C −40°C to 125°C T S = = TMS320F28055, TMS320F28054, TMS320F28053 TMS320F28052, TMS320F28051, TMS320F28050 www.ti.com SPRS797 –NOVEMBER 2012 TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, PN) and temperature range (for example, T). Figure 7-1 provides a legend for reading the complete device name for any family member.

The drift is laser-trimmed to 2.5ppm/°C max C-grade over the industrial temperature range. The REF102 achieves its precision without a heater. This results in low power, fast warm-up, excellent stability, and low noise. The output voltage is extremely insensitive to both line and load variations and can be externally adjusted with minimal effect on drift and stability. Single supply operation from 11.4V to 36V and excellent overall specifications make the REF102 an ideal choice for demanding instrumentation and system reference applications. – + A R2 R3 R4 R6 R1 R5 1 50kΩ 22kΩ 7kΩ 4kΩ 8kΩ DZ1 Noise Reduction Common VOUT Trim V+ 14kΩ 5 2 6 8 4 REF102 REF102 REF102 2 www.ti.com SBVS022A SPECIFIED MAX INITIAL MAX DRIFT PACKAGE TEMPERATURE PACKAGE ORDERING TRANSPORT PRODUCT ERROR (mV) (PPM/°C) PACKAGE-LEAD DESIGNATOR RANGE MARKING NUMBER MEDIA, QUANTITY REF102AU ±10 ±10 SO-8 D –25°C to +85°C REF102AU REF102AU Tube, 100 " ±10 ±10 SO-8 D " REF102AU/2K5 REF102AU/2K5 Tape and Reel, 2500 REF102AP ±10 ±10 DIP-8 P " REF102AP REF102AP Tube, 50 REF102BU ±5 ±5 SO-8 D " REF102BU REF102BU Tube, 100 " ±5 ±5 SO-8 D " REF102BU/2K5 REF102BU/2K5 Tape and Reel, 2500 REF102BP ±5 ±5 DIP-8 P " REF102BP REF102BP Tube, 50 REF102CU ±2.5 ±2.5 SO-8 D " REF102CU REF102CU Tube, 100 " ±2.5 ±2.5 SO-8 D " REF102CU/2K5 REF102CU/2K5 Tape and Reel, 2500 REF102CP ±2.5 ±2.5 DIP-8 P " REF102CP REF102CP Tube, 50 PIN CONFIGURATIONS Top View DIP, SO Input Voltage ...................................................................................... +40V Operating Temperature P, U ................................................................................. –25°C to +85°C Storage Temperature Range P, U ............................................................................... –40°C to +125°C Lead Temperature (soldering, 10s) ............................................... +300°C (SO, 3s) ........................................................... +260°C Short-Circuit Protection to Common or V+ ..............................

The 10V output is derived from a compensated buried zener diode DZ1, op amp A1, and resistor network R1 – R6. Approximately 8.2V is applied to the non-inverting input of A1 by DZ1. R1, R2, and R3 are laser-trimmed to produce an exact 10V output. The zener bias current is established from the regulated output voltage through R4. R5 allows user-trimming of the output voltage by providing for small external adjustment of the amplifier gain. Because the temperature coefficient (TCR) of of R5 closely matches the TCR of R1, R2 and R3 , the voltage trim has minimal effect on the reference drift. The output voltage noise of the REF102 is dominated by the noise of the zener diode. A capacitor can be connected between the Noise Reduction pin and ground to form a lowpass filter with R6 and roll off the high-frequency noise of the zener. DISCUSSION OF PERFORMANCE The REF102 is designed for applications requiring a precision voltage reference where both the initial value at room temperature and the drift over temperature are of importance to the user. Two basic methods of specifying voltage reference drift versus temperature are in common usage in the industry—the “butterfly method” and the “box method.” The REF102 is specified by the more commonly-used “box method.” The “box” is formed by the high and low specification temperatures and a diagonal, the slope of which is equal to the maximum specified drift. Since the shape of the actual drift curve is not known, the vertical position of the box is not known, either. It is, however, bounded by VUPPER BOUND and VLOWER BOUND (see Figure 1). Figure 1 uses the REF102CU as an example. It has a drift specification of 2.5ppm/°C maximum and a specification temperature range of –25°C to +85°C. The “box” height, V1 to V2, is 2.75mV.

REF102CU Output Voltage Drift. REF102 6 www.ti.com SBVS022A INSTALLATION AND OPERATING INSTRUCTIONS BASIC CIRCUIT CONNECTION Figure 2 shows the proper connection of the REF102. To achieve the specified performance, pay careful attention to layout. A low resistance star configuration will reduce voltage errors, noise pickup, and noise coupled from the power supply. Commons should be connected as indicated, being sure to minimize interconnection resistances. OPTIONAL OUTPUT VOLTAGE ADJUSTMENT Optional output voltage adjustment circuits are shown in Figures 3 and 4. Trimming the output voltage will change the voltage drift by approximately 0.008ppm/°C per mV of trimmed voltage. In the circuit in Figure 3, any mismatch in TCR between the two sections of the potentiometer will also affect drift, but the effect of the ΔTCR is reduced by a factor of five by the internal resistor divider. A high quality potentiometer, with good mechanical stability, such as a cermet, should be REF102 1μF Tantalum + RL 1 RL 2 RL 3 V+ (1) 2 (2) (1) (2) 4 6 NOTES: (1) Lead resistances here of up to a few ohms have negligible effect on performance. (2) A resistance of 0.1Ω in series with these leads will cause a 1mV error when the load current is at its maximum of 10mA. This results in a 0.01% error of 10V. FIGURE 2. REF102 Installation.

The circuit in Figure 3 has a minimum trim range of ±300mV. The circuit in Figure 4 has less range but provides higher resolution. The mismatch in TCR between RS and the internal resistors can introduce some slight drift. This effect is minimized if RS is kept significantly larger than the 50kΩ internal resistor. A TCR of 100ppm/°C is normally sufficient. REF102 7 SBVS022A www.ti.com OPTIONAL NOISE REDUCTION The high-frequency noise of the REF102 is dominated by the zener diode noise. This noise can be greatly reduced by connecting a capacitor between the Noise Reduction pin and ground. The capacitor forms a low-pass filter with R6 (refer to the figure on page 1) and attenuates the high-frequency noise generated by the zener. Figure 5 shows the effect of a 1μF noise reduction capacitor on the high-frequency noise of the REF102. R6 is typically 7kΩ so the filter has a –3dB frequency of about 22Hz. The result is a reduction in noise from about 800μVPP to under 200μVPP. If further noise reduction is required, use the circuit in Figure 14. APPLICATIONS INFORMATION High accuracy, extremely low drift, outstanding stability, and low cost make the REF102 an ideal choice for all instrumentation and system reference applications.

The TLE208x also have wider supply-voltage rails, increasing the dynamic-signal range for BiFET circuits to ±19 V. On-chip zener trimming of offset voltage yields precision grades for greater accuracy in dc-coupled applications. The TLE208x are pin-compatible with lower performance BiFET operational amplifiers for ease in improving performance in existing designs. BiFET operational amplifiers offer the inherently higher input impedance of the JFET-input transistors, without sacrificing the output drive associated with bipolar amplifiers. This makes these amplifiers better suited for interfacing with high-impedance sensors or very low level ac signals. They also feature inherently better ac response than bipolar or CMOS devices having comparable power consumption. Because BiFET operational amplifiers are designed for use with dual power supplies, care must be taken to observe common-mode input-voltage limits and output voltage swing when operating from a single supply. DC biasing of the input signal is required and loads should be terminated to a virtual ground node at mid-supply. Texas Instruments TLE2426 integrated virtual ground generator is useful when operating BiFET amplifiers from single supplies. The TLE208x are fully specified at ±15 V and ±5 V. For operation in low-voltage and/or single-supply systems, Texas Instruments LinCMOS families of operational amplifiers (TLC- and TLV-prefix) are recommended. When moving from BiFET to CMOS amplifiers, particular attention should be paid to slew rate and bandwidth requirements and output loading. For BiFET circuits requiring low noise and/or tighter dc precision, the TLE207x offer the same ac response as the TLE208x with more stringent dc and noise specifications.

Internal Input Capacitance typical values Typical values presented in this data sheet represent the median (50% point) of device parametric performance. input bias and offset current At the picoampere bias-current level typical of the TLE208x and TLE208xA, accurate measurement of the bias becomes difficult. Not only does this measurement require a picoammeter, but test socket leakages can easily exceed the actual device bias currents. To accurately measure these small currents, Texas Instruments uses a two-step process. The socket leakage is measured using picoammeters with bias voltages applied but with no device in the socket. The device is then inserted in the socket and a second test is performed that measures both the socket leakage and the device input bias current. The two measurements are then subtracted algebraically to determine the bias current of the device.
