Next generation of automotive powertrain MCU
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.

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). |
