Supporting standards for future automotive MCUs and SoC devices

Renesas Electronics Corporation is to commit to meeting the ISO/SAE 21434 road vehicles cybersecurity engineering international standard for its automotive MCUs and SoC solutions effective with new developments from January 2022. This is part of the company’s continued commitment to implementing robust automotive cybersecurity management systems (CSMS) as part of the new UN Economic Commission for Europe (UNECE) regulation UN R155.

The commitment reaffirms to OEMs and Tier 1 suppliers that the company will continue to meet its CSMS obligations. All future company automotive MCUs and SoCs will sequentially obey the ISO/SAE 21434 standard with development beginning from January 2022. This includes the company’s 16-bit RL78 and 32-bit RH850 MCUs, as well as the R-Car SoC family.

Both ISO/SAE 21434 and UNECE UN R155 need cybersecurity to be enforced over the complete automotive supply chain. Effective July 2022, for new vehicle types, automotive OEMs will be expected to have an automotive CSMS in place to assure that the stringent cybersecurity processes have been implemented to obtain vehicle type approval. With the company’s commitment to ISO/SAE 21434, OEMs and Tier 1 suppliers can have faith in adopting its solutions.

“ISO/SAE 21434 is setting the international standard that outlines the requirements for security throughout the entire automotive life cycle, and Renesas has now adopted this standard. We will establish security process with requirement definition by security analysis, implementation and evaluation, utilising and optimising existing development process,” said Takashi Yasumasu, vice president of Automotive Core Technology Development Division at Renesas. “This enables us to provide products and solutions with appropriate risk mitigation measures according to the risk assessment. Renesas aims to be a trusted partner for customers around the world in the face of the growing automotive security threats posed by CASE.”
