The Texas Instruments Tiva™ C Series TM4C123G LaunchPad (EK-TM4C123GXL) concept is an extremely low-cost, expandable evaluation system for TI microcontrollers. This concept began with the tremendously successful MSP430™ LaunchPad which introduced a large number of engineers to the TImultiProductLinkMSP430 family of microcontrollers (MCUs). The Tiva Series of 32-bit ARM® Cortex™-M4MCU family expands that success by introducing the Tiva C Series TM4C123G LaunchPad featuring the Tiva C Series TM4C123GH6PM microcontroller. A Tiva C Series LaunchPad consists of a target microcontroller, an in-circuit debug interface (ICDI) such as JTAG, a regulated power supply, a minimal microcontroller support circuit, a user interface, and a set of expansion headers. These expansion headers are referred to as the BoosterPack Interface. A BoosterPack is an expansion card designed for this interface. The BoosterPack interface provides a mechanism for developers to easily extend the Tiva C Series LaunchPad with application- and userspecific functions. The EK-TM4C123GXL LaunchPad provides a BoosterPack interface that is compatible with the MSP430LaunchPad. In addition, the TM4C123 LaunchPad provides access to additional Tiva C Series functionality through an extended BoosterPack interface called the BoosterPack XL Interface. BoosterPack interfaces with highly similar functionality for expansion will be available for the Tiva C Series LaunchPad, in addition to microcontroller-family-specific functionality available on a BoosterPack XL Interface for additional options. The Tiva C Series LaunchPad design highlights the TM4C123GH6PMI microcontroller USB 2.0 device interface, hibernation module, and motion control pulse-width modulator (MC PWM) module. The Tiva C Series LaunchPad also features programmable user buttons and an RGB LED for custom applications. The stackable headers of the Tiva C Series TM4C123G LaunchPad BoosterPack XL interface demonstrate how easy it is to expand the functionality of the Tiva C Series LaunchPad when interfacing to other peripherals on many existing BoosterPack add-on boards as well as future products. Key Applications: Low power, hand-held smart devices, Gaming equipment, Home and commercial site monitoring and control, Motion control, Medical instrumentation, Test and measurement equipment, Factory automation, Fire and security, Smart Energy/Smart Grid solutions, Intelligent lighting control, Transportation

Meet your LaunchPad

On-board Emulation

The EK-TM4C123GXL LaunchPad features on-board emulation, which means you can program and debug your projects without the need for additional tools.

BoosterPack Compatibility

Two dual-gender, 20-pin stackable headers provide great connection options out of the box. These 40 pins allow you to add support for displays, wireless interfaces, sensors and other capabilities to your projects very easily and also offer basic compatibility with existing MSP430 and C2000 LaunchPads.
