The RH850/E2H 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 the certification. Over The Air (OTA) updating for automatically updating software wirelessly to a safer control program is also supported. Design resources are available here to help you get your design to market as quickly as possible.

Hardware Tools
Programming Tools
We also offer a newer and faster emulator for separate purchase. While there is a debugger included in the starter kit, we offer the option here to purchase the newer and faster E2 emulator/debugger for programming and debugging RH850 E2x devices.
In addition to a hardware emulator/debugger, we also offer the Renesas Flash Programmer for free download. The Flash programmer contains a simple-to-use graphical user interface which is ideal for first-time developers.
