Jul 31 2023 2023-07 Power Renesas Electronics America

Renesas Electronics, a global provider of semiconductor solutions, announced that its automotive cybersecurity management System (CSMS) for microcontroller (MCU) and system-on-chip (SoC) development has been defined and implemented in accordance with the international standard ISO/SAE 21434:2021. The CSMS framework is suitable for Renesas Electronics' design center in Musashi, Japan, and has been certified by TUV Rheinland Industrie Service GmbH.

The certification reaffirms Renesas Electronics' commitment to Tier 1 suppliers and vehicle manufacturers (Oems) that Renesas will continue to fulfill its CSMS role in helping vehicle manufacturers obtain vehicle type certification as required by the recent United Nations Economic Commission for Europe (UNECE) UNR155 regulation. As stated in an earlier press release, all Renesas Automotive MCUS and SOCs developed after January 1, 2022 will follow the certified ISO/SAE 21434:2021 Cybersecurity Management System (CSMS) development process, including the 16-bit RL78 and 32-bit RH850 MCUS. And the popular R-Car SoC family.

Yasusu Takeshi, Vice President of the HPC Core Technology Division at Renesas said: "Through independent third-party certification, customers can be confident that Renesas' management of CSMS processes meets the requirements defined in ISO/SAE 21434:2021. Oems and Tier 1 suppliers can streamline their vehicle approval process with this independent third-party certification without having to conduct their own audits of our process."

Renesas has contributed significantly to the development of the ISO/SAE 21434:2021 standard worldwide, and its commitment and dedication to cybersecurity extends beyond the automotive industry. In 2019, Renesas Electronics received TUV Rheinland certification in accordance with IEC 62443-4-1 standards. This standard specifies the process requirements for the safe development of industrial products.

Renesas Electronics continues to develop safe and reliable products for its customers. The ISO/SAE 21434:2021 certification is Renesas Electronics' latest achievement in the field of automotive MCUS and SOCs following the ISO 26262 certification. Customers can be assured that the use of Renesas electronic MCUS and SOCs in next-generation in-vehicle systems will comply with international standards for product cybersecurity and functional safety.
