Safe and secure high-end microcontroller for powertrain (function-reduced version of RH850/E1M-S) with many built-in functions for realizing functional safety (ISO 26262)

The RH850/E1L is a function-reduced version of the RH850/E1M-S. The RH850/E1L microcontroller has a maximum operating frequency of 240MHz. With two A/D converters (SAR and delta-sigma), a digital filter engine, an advanced timer unit (ATU-IV), and more, this MCU realizes high-precision complex powertrain control. Many functions for realizing functional safety (ISO 26262) are built in, helping to simplify the certification process.

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).
