See the LM4F120H5QR microcontroller data sheet (order number DS-LM4F120H5QR) for complete device details. Most of the microcontroller signals are routed to 0.1" pitch headers. An internal multiplexer allows different peripheral functions to be assigned to each of these GPIO pads. When adding external circuitry, consider the additional load on the evaluation board’s power rails. The LM4F120H5QR microcontroller is factory-programmed with a quickstart demo program. The quickstart program resides in on-chip Flash memory and runs each time power is applied, unless the quickstart application has been replaced with a user program. USB Device The Stellaris® LaunchPad includes a USB Micro-B connector to allow for USB 2.0 Device operation. The signals shown in Table 2-1 are used for USB Device. Table 2-1. USB Device Signals GPIO Pin Pin Function USB Device PD4 USB0DM D- PD5 USB0DP D+ When connected as a USB Device, the evaluation board can be powered from either the Stellaris® ICDI or the USB Device connectors. The user can select the power source by moving the POWER SELECT switch (SW3) to the Device position. See the Power Management schematic on page 19 User Switches and RGB User LED The Stellaris® LaunchPad comes with an RGB LED. This LED is used in the preloaded RGB quickstart application and can be configured for use in custom applications. Two user buttons are included on the board. The user buttons are both used in the preloaded quickstart application to adjust the light spectrum of the RGB LED as well as go into and out of hibernation. The user buttons can be used for other purposes in the user’s custom application. The evaluation board also has a green power LED. Table 2-2 shows how these features are connected to the pins on the microcontroller. Table 2-2.

Highlighted functions in Table 2-3, "J1 Connector" on page 11 and Table 2-4, "J2 Connector" on page 11 indicate configuration for compatibility with the MSP430 LaunchPad. A complete list of Stellaris® BoosterPacks and Stellaris LaunchPad-compatible MSP430 BoosterPacks is available at www.ti.com/stellaris-launchpad. Power Management (Schematic on page 19) Power Supplies The Stellaris® LaunchPad can be powered from one of two power sources: On-board Stellaris® In-Circuit Debug Interface (ICDI) USB cable (Debug, Default) USB Device cable (Device) The POWER SELECT switch (SW3) is used to select one of the two power sources. Select only one source at a time. Hibernate The Stellaris® LaunchPad provides an external 32.768 kHz crystal (Y1) as the clock source for the LM4F120H5QR’s Hibernation module clock source. The current draw while in Hibernate mode can be measured by making some minor adjustments to the Stellaris® LaunchPad. This is explained in more detail later in this section. The conditions that can generate a wake signal to the Hibernate module on the Stellaris® LaunchPad are waking on a Real-time Clock (RTC) match and/or waking on assertion of the WAKE pin.1 The second user switch (SW2) is connected to the WAKE pin on the microcontroller. The WAKE pin, as well as the VDD and HIB pins, are easily accessible through breakout pads on the Stellaris® LaunchPad. See Appendix A, “Schematics” on page 22 for details. There is no external battery source on the Stellaris® LaunchPad Hibernation module, which means the VDD3ON power control mechanism should be used. This mechanism uses internal switches to remove power from the Cortex-M4F processor as well as to most analog and digital functions while retaining I/O pin power. To measure the Hibernation mode current or the Run mode current, the VDD jumper that connects the 3.3 V pin and the MCU_PWR pin must be removed. See Appendix A, “Schematics” on page 17 for details on these pins and component locations. An ammeter should then be placed between the 3.3 V pin and the MCU_PWR pin to measure IDD (or IHIB_VDD3ON). The LM4F120H5QR microcontroller uses VDD as its power source during VDD3ON Hibernation mode, so IDD is the Hibernation mode (VDD3ON mode) current. This measurement can also be taken during Run mode, which measures IDD the microcontroller running current. Clocking The Stellaris® LaunchPad uses a 16.0-MHz crystal (Y2) to complete the LM4F120H5QR microcontroller's main internal clock circuit. An internal PLL, configured in software, multiples this clock to higher frequencies for core and peripheral timing. The Hibernation module is clocked from an external 32.768 kHz crystal (Y1). 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 application). 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. August 29, 2012 13 Stellaris® LM4F120 LaunchPad User’s Manual Reset The RESET signal into the LM4F120H5QR microcontroller connects to the RESET switch and to the Stellaris® ICDI circuit for a debugger-controlled reset. External reset is asserted (active low) under any of three conditions: Power-on reset (filtered by an R-C network) RESET switch held down By the Stellaris® ICDI circuit when instructed by the debugger (this capability is optional, and may not be supported by all debuggers) Stellaris In-Circuit Debug Interface (ICDI) (Schematic on page 20) Stellaris® In-Circuit Debug Interface (ICDI) The Stellaris® LaunchPad evaluation board comes with an on-board Stellaris® In-Circuit Debug Interface (ICDI). The Stellaris® ICDI allows for the programming and debug of the LM4F120H5QR using LM Flash Programmer and/or any of the supported tool chains. Both JTAG and Serial Wire Debug (SWD) are supported. Table 2-7 shows the pins used for JTAG and SWD. These signals are also mapped out to easily accessible breakout pads and headers on the board. Table 2-7.

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 which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
