The RH850/E1L 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). It 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.
