RH850/E1M-S2 microcontrollers are suitable for engine control and at 320 MHz have the highest class of operating frequency among automotive microcontrollers. They are also equipped with large-capacity on-chip code flash and RAM.
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.

Software Design Support
| Title | Description |
|---|---|
| CS+ | This integrated development environment (IDE) can be used for coding, assembly, compiling, and simulation. |
| e² studio | This integrated development environment (IDE) is based on the popular combination of the open-source Eclipse IDE and its CDT plug-in that enables C/C++ language development. |
| E2 emulator | This on-chip debugging emulator has advanced features that improve the efficiency of development. In addition to the basic functions from debugging to flash programming, this emulator supports hot plug-in and external triggers as standard items. This emulator also helps to reduce development time by downloading at high speeds (compared to the E1 emulator) and the ability to work in combination with various solutions such as the CAN communication time measurement solution by systems under development. |
| E1 emulator | This on-chip debugging emulator is a standard model which provides basic debugging functions (production is to be discontinued at the end of December 2019). |
