See the DS-TM4C123GH6PGE microcontroller data sheet for complete device details. Most of the microcontroller signals are routed to 0.1" pitch break-out pads and labeled with their GPIO reference. An internal multiplexer allows different peripheral functions to be assigned to each of these GPIO pads. When adding external circuitry, consideration should be given to the additional load on the development board’s power rails. The Tiva PinMux Utility can be used to quickly develop pin assignments and the code required to configure them. The TM4C123GH6PGE microcontroller is factory-programmed with a quickstart data logger demo program. The quickstart program resides in on-chip flash memory and runs each time power is applied, unless the application has been replaced with a user program. 2.1.2 USB Host/Device/OTG The DK-TM4C123G includes a USB Micro-AB (OTG) connector to allow for USB Host, Device, and OTG operation. The following signals are used for USB OTG.: Table 2-1. USB Host/Device/OTG Signals GPIO Pin Pin Function USB OTG PL6 USB0DP D+ PL7 USB0DM D- PB0 USB0ID ID PB1 USB0VBUS USB VBUS Load Switch PG4 USB0EPEN USB VBUS Power Enable (EN2) PG5 USB0PFLT Power Fault ( OC2 ) In USB Host mode, the development board can provide power to the OTG connector. The USB0EPEN signal controls the Channel 2 Enable (EN2) of a Texas Instruments’ TPS2052B Load Switch (U7), which enables power to the connector's VBUS pin. The POWER SELECT jumper must be in the “ICDI” position. In Device mode, the development board can be powered from either the ICDI or the OTG connectors. The user can select the power source by moving the POWER SELECT jumper to the appropriate position. In OTG mode, the POWER SELECT jumper's position requires special consideration depending on the system and code configuration. 8 Hardware Description SPMU357B – August 2013 – Revised March 2014 Submit Documentation Feedback Copyright © 2013–2014, Texas Instruments Incorporated www.ti.com Data Logger, Motion Sensor, Temperature Sensors, CAN Transceiver, OLED, and SD Card (Schematic page 2) 2.1.3 User Switches and User LED Five switches on the board provide navigation and selection for the preloaded quickstart application. These switches can be used for other purposes in the user’s custom applications. The development board also has a green user LED. Table 2-2 shows how these features are connected to the pins on the microcontroller. Table 2-2.

The remaining pins are broken out to headers located near the hardware feature that uses them. These are also on a 0.1" grid. All of these headers are labeled with the port and pin name, and, where possible, labeled with their function. See Schematics for detailed information on these signals. 2.2 Data Logger, Motion Sensor, Temperature Sensors, CAN Transceiver, OLED, and SD Card (Schematic page 2) 2.2.1 Data Logger The DK-TM4C123G comes with a quickstart application loaded into the Flash memory. This application implements a multi-channel data logger that can measure up to four analog channels (0-20 V), nine axes from the motion sensor, two analog temperature sensors, and the microcontroller running current. A Windows quickstart companion application is also provided on the development kit USB flash drive and serves as a secondary display for the Data Logger application. See Software Description for more information. 2.2.2 4-Channel Analog Measurement An 8-position screw terminal block is included on the development board to make easy connections to external signals.Table 2-3 shows how the screw terminals and channels are arranged.

A voltage divider on each channel scales the 0-20 V range on the terminal to the 0-3 V range of the 12-bit Analog-to-Digital Converter (ADC) of the TM4C123GH6PGE microcontroller. Each scaled-down signal passes through a unity-gain amplifier to provide a low-impedance source for the microcontroller’s ADC. Below are some useful equations to keep on hand when using the four data logger channels.

Table 2-5 shows the signal used by the temperature sensor. Table 2-5. Temperature Sensor Signals GPIO Pin Pin Function Temp.

The output of a Texas Instruments INA198 Current Shunt Amplifier (U15) is connected to the ADC on the microcontroller. This amplifier increases the voltage drop on a 0.1-Ohm current shunt resistor in line with the VDD source for the microcontroller. Table 2-7 shows the signal used to measure the amplifier output. Table 2-7. Microcontroller Running Current Signals GPIO Pin Pin Function Amplifier PP0 AIN23 OUT See Current Shunt Resistors for more details on calculating the running current from the ADC readings. 2.2.6 CAN Transciever A Texas Instruments SN65HVD1050D High-Speed CAN Transceiver is included on the development kit. The DK-TM4C123G can easily be connected to other CAN enabled devices via the screw terminals on the board, see Figure 2-2. The following signals are used for CAN: Table 2-8. CAN Transceiver Signals GPIO Pin Pin Function CAN Transciever PE4 CAN0RX RXD PE5 CAN0TX TXD The CAN bus signals from the transceiver are brought out on the screw terminals alongside the analog channels. Depending on the position of the development kit in the network, a termination resistor may be required. A standard 0.125 W through-hole resistor can easily be screwed into the terminals in addition to the bus wires. For example: +VBUS CH3 CH2 CH1 CH0 GND CANH 120 CANL Figure 2-2.

The OLED display is powered from the on-board 13 V regulator, which must be enabled before using the display. Data is written to the display using the SSI2 peripheral. Table 2-9 shows the signals used by the display. Table 2-9.

Table 2-10 shows the signals used with the SD card. Table 2-10. SD Card Signals 2.3 GPIO Pin Pin Function PA5 SSI0TX SD Card Function DI PA4 SSI0RX DO PA3 SSI0FSS CS PA2 SSI0CLK CLK Hibernate, Current Shunts, Power Supplies, Reset and Crystals (Schematic page 3) 2.3.1 Hibernate The DK-TM4C123G provides a 32.768 kHz crystal (Y1) as the clock source for the TM4C123GH6PGE’s Hibernation module. Along with a 3.0-V CR2032 lithium coin-cell backup battery that is connected to the VBAT pin and provides power to the Hibernation module when the microcontroller is in Hibernate mode. The current draw while in Hibernate mode can be measured indirectly by measuring the voltage across the 1-kΩ current shunt resistor. See Current Shunt Resistors for more details. Several conditions can generate a wake signal to the Hibernate module; waking on a Real-time Clock (RTC) match, waking on low battery, and/or waking on assertion of the WAKE pin. (1) The SELECT/WAKE switch is connected to the WAKE pin on the microcontroller. When the microcontroller is configured to wake on WAKE assertion, the switch can be used to wake the part from Hibernate mode. The SELECT/WAKE switch is also connected to PM4 by way of a diode to prevent PM4 from asserting WAKE when the part enters Hibernate mode. See Appendix A: Schematics for details. To achieve the lowest power consumption while in Hibernate mode, the HIB signal is connected to the Channel 1 Enable (EN1) signal of the Texas Instruments TPS2052B load switch (U7). In Hibernate mode, the HIB signal is asserted and the load switch cuts main power to the entire board, excluding the on-board ICDI. The Hibernation module is powered solely by the back-up battery. (1) If the board does not turn on when you connect it to a power source, the microcontroller might be in Hibernate mode (depending on the programmed applications). You must satisfy one of the programmed wake conditions and connect the power to bring the microcontroller out of Hibernate mode and turn on the board. SPMU357B – August 2013 – Revised March 2014 Submit Documentation Feedback Copyright © 2013–2014, Texas Instruments Incorporated Hardware Description 13 Hibernate, Current Shunts, Power Supplies, Reset and Crystals (Schematic page 3) www.ti.com The DK-TM4C123G has additional circuitry that allows the development board to be turned on when a battery is not present or when the battery voltage is too low. A Texas Instruments TPS3803-01 Voltage Detector (U12) monitors VBAT and produces a VBAT_GOOD signal when the battery voltage is above 2.1 V. Using standard logic gates and the state of VBAT and VDD, the HIB signal can be forced high when VBAT is not valid and the microcontroller is not already powered. With this circuit, a USB-powered board can turn itself on when the back-up battery is either missing or fully discharged. See Appendix A: Schematics for more details. This additional circuitry may not be needed in all applications. For example, when using the Hibernate module in VDD3ON mode, power is cut to the microcontroller internally which eliminates the need to turn off an external supply using HIB. By default the DK-TM4C123G is not configured to use VDD3ON mode; HIB is connected to the load switch, WAKE is pulled up to VBAT, and VBAT is connected to the battery. VDD3ON mode can be used if the board is reconfigured as follows (2): Disconnect HIB from the load swich by removing the HIB DISC jumper (JP3). Next, ensure that WAKE is pulled HIGH either by leaving the battery connected or by removing the battery and connecting VBAT to VDD. CAUTION Failure to remove the battery when connecting VBAT to VDD will damage the battery and can cause a fire. There are many different ways that Hibernate mode can be implemented in an embedded system. Each implementation requires its own special design considerations. 2.3.2 Current Shunt Resistors The development board provides two current shunt resistors to measure the MCU running current, IDD, and the hibernation battery current, IVBAT. IDD can be measured by the MCU through a TI INA198 Current Shunt Amplifier (U15). See MCU Running Current section. IBAT must be measured externally. 2.3.2.1 Microcontroller Running Current IVDD The shunt resistor for IDD, RVDDSHUNT, is 0.1Ω and the INA198 amplifier gain is 100 V/V. Therefore: VVDDSHUNT VVDDSHUNT IDD R VDDSHUNT 0.1 (8) VADC (9) VVDDSHUNT u Gain VVDDSHUNT u 100 Given the ADC measurement, you can calculate IVDD: § VADC · VVDDSHUNT ¨© 100 ¸¹ VADC IDD R VDDSHUNT 0.1 10 (10) Or simply, 10mV per mA. 2.3.2.2 Hibernation Battery Current IBAT The shunt resistor for IVBAT, RVBATSHUNT, is 1kΩ. VSHUNT VSHUNT IDD RSHUNT 1000 (11) Or simply 1 mV per µA. (2) 14 In addition to reconfiguring the hardware, the software must also be reconfigured to use VDD3ON mode.

An internal PLL, configured in software, multiplies this clock to higher frequencies for core and peripheral timing. The Hibernation module is clocked off of an external 32.768 kHz crystal (Y1). 2.3.4 Reset The RESET signal into the TM4C123GH6PGE microcontroller connects to the RESET switch and to the ICDI circuit for a debugger-controlled reset. External reset is asserted (active low) under any one of these conditions: • Power-on reset • RESET switch held down • By the ICDI circuit when instructed by the debugger (this capability is optional, and may not be supported by all debuggers). The OLED display has special reset timing requirements requiring a dedicated control line from the microcontroller. 2.3.5 Power Supplies and Jumper The DK-TM4C123G can be powered from one of two power sources: • ICDI USB cable (default) • USB OTG cable A moveable jumper shunt on the POWER SELECT headers is used to select one of the two power sources. Only one source should be selected at a time. See USB Host/Device/OTG for the recommended jumper positions for the specific USB modes. The development board is designed to provide power to a limited amount of external circuitry. Table 2-11 shows the board’s power requirements and Table 2-12 shows the board’s breakout limitations. Table 2-11. Power Requirements Board Supply ICDI USB Cable USB OTG Cable Min Typical Max Unit 4.75 5 5.25 V Table 2-12. Breakout Requirements Breakout Condition Max Unit 260 mA +3.3V at 260mA, OLED on 350 mA +3.3V at 260mA, OLED off 380 mA +3.3V +5.0V (1) (1) (2) (2) This represents the +5.0V breakout and the +VBUS breakout. Total current = I5V + IVBUS +5.0V is switched by the load switch (U7); however +VBUS is always connected.

The ICDI allows for programming and debugging of the TM4C123GH6PGE using LM Flash Programmer and/or any of the supported tool chains. Both JTAG and Serial Wire Debug (SWD) are supported. An external debugger can be connected to the development board through the 2 x 5 fine pitch (0.05”) ARM JTAG header (J1). When connecting an external debugger, pin 3 of the JTAG header must be tied to ground in order for the ICDI to release control of the JTAG signals. The ARM standard pinout specifies pin 3 as ground, therefore, any standard third-party debugger should work. Table 2-13 shows the pins used for JTAG and SWD. Table 2-13. In-Circuit Debug Interface (ICDI) Signals GPIO Pin Pin Function JTAG Header Pin PC0 TCK/SWCLK 4 PC1 TMS/SWDIO 2 PC2 TDI 8 PC3 TDO/SWO 6 RST RST 10 ICDI Function - EXTDBG 3 See Appendix A: Schematics for the full header pinout. In addition, the ICDI can debug an external target using the header locations near the JTAG connector. The on-board TM4C123GH6PGE must be held in reset by installing a 2-pin jumper in the DEBUG OUT EN jumper position (JP1). The HIB DISC (located near the SELECT/WAKE button) is a conveniently available jumper to repurpose. The following diagram illustrates how an external target can be connected. In this configuration, the debugger will not have control of the hardware reset line RST. GND TDI TDO TCK TMS Install Jumper Figure 2-3.

User shall be solely responsible for proper disposal and recycling of EVMs consistent with all applicable federal, state, and local requirements. Certain Instructions. User shall operate EVMs within TI’s recommended specifications and environmental considerations per the user’s guide, accompanying documentation, and any other applicable requirements. Exceeding the specified ratings (including but not limited to input and output voltage, current, power, and environmental ranges) for EVMs may cause property damage, personal injury or death. If there are questions concerning these ratings, user should contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the applicable EVM user's guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using EVMs’ schematics located in the applicable EVM user's guide. When placing measurement probes near EVMs during normal operation, please be aware that EVMs may become very warm. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use EVMs. Agreement to Defend, Indemnify and Hold Harmless. User agrees to defend, indemnify, and hold TI, its directors, officers, employees, agents, representatives, affiliates, licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of, or in connection with, any handling and/or use of EVMs. User’s indemnity shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if EVMs fail to perform as described or expected. Safety-Critical or Life-Critical Applications. If user intends to use EVMs in evaluations of safety critical applications (such as life support), and a failure of a TI product considered for purchase by user for use in user’s product would reasonably be expected to cause severe personal injury or death such as devices which are classified as FDA Class III or similar classification, then user must specifically notify TI of such intent and enter into a separate Assurance and Indemnity Agreement. RADIO FREQUENCY REGULATORY COMPLIANCE INFORMATION FOR EVALUATION MODULES Texas Instruments Incorporated (TI) evaluation boards, kits, and/or modules (EVMs) and/or accompanying hardware that is marketed, sold, or loaned to users may or may not be subject to radio frequency regulations in specific countries. General Statement for EVMs Not Including a Radio For EVMs not including a radio and not subject to the U.S. Federal Communications Commission (FCC) or Industry Canada (IC) regulations, TI intends EVMs to be used only for engineering development, demonstration, or evaluation purposes.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
