Key Document


The Hercules™ RM46x LaunchPad™ Development Kit is an inexpensive evaluation platform designed to help you get started quickly in evaluating and developing with the Hercules microcontroller platform. The LaunchPad Development Kit is based on the IEC 61508 SIL 3 certified RM46L852, which is a lockstep ARM® Cortex®-R4F based MCU with integrated safety features and peripherals such as two 12-bit ADCs, programmable High-End timers, motor control peripherals (eQEP, eCAP, ePWM), USB, Ethernet, MibSPI and serial communication interfaces. Hercules RM MCUs can help reduce the development effort of IEC 61508 functional safety applications.

The LaunchPad features on-board emulation for programming and debugging, push buttons, LEDs and ambient light sensor & two standard 40 pin BoosterPack expansion connectors (only one header is populated) to support a wide range of plug-in BoosterPack modules for added functionality such as displays, wireless sensors & more.

This LaunchPad comes pre-programmed with a demo code enabling users to easily learn about the key safety, data acquisition and control features of the Hercules MCU platform. Find more information about this demo on the wiki: http://processors.wiki.ti.com/index.php/LAUNCHXL2_RM46:_Project_1.

Find additional information on LaunchPad Development Kits, supported BoosterPacks and available resources at ti.com/launchpad. Visit the LAUNCHXL2-RM46 Wiki for software downloads and other resources. Explore different applications on your LaunchPad Development Kit with BoosterPack plug-in modules. Demo software for Ethernet connectivity using lwIP can also be found on the Wiki.
