High-end MCU designed especially for electronic power steering systems, supporting the new CAN-FD communication standard
The RH850/P1M-E microcontroller is the successor of the successful RH850/P1M series, supporting now also the CAN-FD.Like its predecessor, the RH850/P1M-E has been designed for systems with ASIL-D safety level, featuring many safety functions such as lockstep CPU, ECC, and BISTs (Built-in Self Tests). Along with a variety of interfaces (e.g. SENT a digital i/f for sensors) it also has a dedicated security module(ICU-S), implemented in hardware, to protect sensitive data like secret keys. With its low power consumption, the MCU is well suited for today’s requirements regarding energy efficient ECUs in automotive area.

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). |
