TMS470M ARM Cortex™-M3

The Hercules™ TMS470M microcontroller family enables developers to easily create safety-related applications for the transportation industry. The TMS470M value-line microcontrollers use the ARM® Cortex™-M3 CPU running at 80MHz and offer Flash memory options ranging from 256KB to 640KB (including up to 128KB EEPROM emulation capability) and RAM memory ranging from 16KB to 64KB.

With built-in safety features like CPU and RAM self test (BIST) engines, error correction code (ECC) and parity-checking, the devices are a great extension to the Hercules Safety MCU platform.
