Overview

The LAUNCHXL2-RM46 is a development platform for the Hercules RM46x series of high-performance ARM Cortex-R4F safety microcontrollers. Designed for functional safety applications, this board provides an accessible entry point to evaluate a dual-core lockstep architecture running at up to 220MHz.

Why Choose This Part

This platform features comprehensive hardware diagnostics including ECC on Flash and SRAM, and clock/voltage monitoring. With 1280KB of Flash and 192KB of RAM, it offers significant headroom for safety-critical firmware while supporting multiple communication interfaces like CAN, LIN, and Ethernet.

Applications

Industrial Safety Controllers
Utilizing lockstep CPUs and built-in self-tests to meet SIL-3 safety standards in factory automation.
Braking and Chassis Control
Leveraging the hardware integrity of the RM46x for automotive-grade reliability and real-time response.
Medical Equipment Control
Ensuring deterministic execution and memory protection for critical patient-care systems.
Railway Signaling
Implementing fail-safe logic using integrated hardware diagnostics and error signaling modules.

Getting Started

To begin development, download the HALCoGen GUI-based configuration tool and Code Composer Studio (CCS). The board includes an integrated XDS110 debug probe, allowing for immediate programming and debugging via the USB interface without external hardware.

Also Consider

LAUNCHXL2-TMS57012 TITexas Instruments - An alternative Hercules safety platform optimized for automotive AEC-Q100 applications with similar lockstep features.
Tiva C Series Connected LaunchPad TITexas Instruments - Ideal if high-performance connectivity and Ethernet are required without the specific functional safety hardware overhead.
STM32 Nucleo-144 H743ZI2 STMicroelectronics - Provides a higher clock speed and larger memory footprint if functional safety certification is not the primary design requirement.
