Renesas’ Chips To Power Toyota’s Self-driving Cars


Renesas announced that it will provide chips for Japanese automaker Toyota’s self-driving cars, which are presently under development and scheduled for commercial launch in 2020.

Renesas’ R-Car SoC and RH850 MCU to power Toyota’s Model Year 2020 autonomous-driving vehicles

Renesas stated that its solution for Toyota’s autonomous vehicles includes the R-Car system-on-chip (SoC), which serves as an electronic brain for in-vehicle infotainment and advanced driver-assistance systems (ADAS), and the RH850 microcontroller (MCU) for automotive control.

“This two chips together offer a comprehensive semiconductor solution that covers peripheral recognition, driving judgements, and body control”, according to the company.


“Toyota selected Renesas as the key semiconductor supplier for its “Highway Teammate”, an autonomous-driving prototype car designed to merge, pass, change lanes, and perform other actions during highway driving, under supervision. Production vehicles are planned for sale by 2020”, the announcement said.

The R-Car chip will power Denso’s engine control unit (ECU), which will be used for Toyota’s upcoming autonomous-driving cars. This chip will act as the electronic brain for the autonomous-driving system, providing highly accurate intelligence on the vehicle’s position within its environment and making real-time decisions on vehicle control and active safety maneuvers based on sensor data.

The second chip, called RH850, is also selected to control driving, steering, and braking functions based on the judgements made by the R-Car SoC.
