Description
The RH850/E2M microcontrollers operate at 400 MHz and are equipped with large-capacity code flash and RAM of the highest speed class, which is necessary for real-time control. By leveraging multiple G4MH cores, the RH850/E2M supports even more advanced functionality, and many built-in functions such as security functions for Evita Medium and functional safety (ISO 26262) functions make it easier to get certification. Over The Air (OTA) updating for automatically updating software wirelessly to a safer control program is also supported.
