Automotive Microcontrollers for Engine Control
Jump to Page Section:
Overview
Description
RH850/E1M-S2 are suitable for engine control, and at 320 MHz have the highest class of operating frequency among automotive microcontrollers. The CPU core of the RH850/E1M-S2 delivers 30% better performance for engine control system applications than its predecessor. The RH850/E1M-S2 supports the SENT communication standard for sensor information, and also supports not only CAN FD for higher speed in-vehicle networks, but also ICU-S for the automotive security that will be demanded by cars going forward. It also has many built-in functions for realizing functional safety (ISO 26262) that facilitate certification.
