Hercules Platform Overview

ARM® Based Safety MCUs


The Hercules safety microcontroller platform consists of three ARM® Cortex®-R4F and Cortex®-R5F based microcontroller families: TMS470M, TMS570, RM4x and RM57. It provides advanced integrated safety features designed specifically for IEC 61508 and ISO 262622 safety critical applications and offers several options for performance, connectivity, safety features, and memory. Key markets include industrial automation, motor control, medical, automotive and transportation, space, avionics and defense applications.


TMS470M offers a value line aimed at transportation and safety applications based on the ARM® Cortex®-M processor. TMS570 provides high performance using dual CPU lockstep architecture based on the ARM® Cortex®-R processor for transportation and safety applications. RM4x and RM57 family provides high performance using dual CPU lockstep architecture based on the ARM® Cortex®-R processor for industrial and medical safety applications.
