28nm Flash MCU For Future Autonomous & Green Cars


To fulfill the high-performance and demanding safety requirements of future autonomous-driving and green cars, Renesas has unveiled a 28nm flash memory MCU series that can achieve up to six 400 MHz CPU cores and 9600 MIPS processing capabilities. The series also claims improved functional safety for connected cars.

These MCUs can be applied to applications such as autonomous vehicle sensor control, fuel-efficient engine control for green vehicles and highly-efficient motor inverter controls.

The new RH850/E2x Series allows high integration densities that are required to achieve miniaturization and higher efficiency in the motors and inverters used in electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV), noted Renesas.


The MCU series is equipped with up to 16 MB of flash ROM which supports advanced OTA updates which automatically and wirelessly updates the ECU software to control programs with improved safety.

The RH850/E2x Series also comes with improved serial interfaces, including up to ten channels of CAN FD and one Ethernet channel.

Another compelling attribute offered by the MCUs is enhanced functional safety for autonomous-driving vehicles. The components target ASIL-D, the highest level of the ISO 26262 functional safety standard for automotive E/E systems. This feature immediately detects faults should a malfunction occur and allow system safety to be maintained.

As noted by Renesas, Car OEMs and Tier 1 manufacturers, such as Denso Corporation, have already started to adopt the new 28nm MCU, recognizing the MCU’s superior processing performance capable of developing next-generation fuel-efficient engines.

Samples of this MCU are available now.
