Renesas Electronics Announces Full Support for the ISO/SAE 21434 Standard for Future Automotive-Grade MCUs and SoCs

Tokyo, Japan, October 8, 2021 – Renesas Electronics Group (TSE: 6723), a global supplier of semiconductor solutions, today announced that Renesas’ automotive-grade microcontrollers ( MCU) and system-on-chip (SoC) solutions will fully meet the ISO/SAE 21434 international standard for road vehicle cybersecurity engineering. This move by Renesas follows the company’s ongoing commitment to automotive cybersecurity and aims to establish and implement a robust Cybersecurity Management System (CSMS) as part of the new United Nations Economic Commission for Europe (UNECE) regulation UN R155 .

This commitment also reaffirms to OEMs (original equipment manufacturers, original equipment manufacturers) and Tier 1 suppliers that Renesas will continue to fulfill its CSMS responsibilities. Starting in January 2022, all future automotive MCUs and SoCs from Renesas will comply with the ISO/SAE 21434 standard; including the 16-bit RL78 and 32-bit RH850 MCUs, as well as the popular R-Car SoC product family.

Both ISO/SAE 21434 (published on 31 August 2021) and UNECE UN R155 require the implementation of cybersecurity management throughout the automotive supply chain. From July 2022, automotive OEMs will be required to establish an in-vehicle CSMS for new models, ensuring that stringent cybersecurity processes are in place to obtain vehicle type approval. With Renesas’ commitment to ISO/SAE 21434, OEMs and Tier 1 suppliers can rely even more on Renesas solutions.

“ISO/SAE 21434 sets the standard for safe connected vehicles. Renesas has a comprehensive process for this, including safety analysis and assessments; this allows us to assess risks and adopt risk mitigation policies to provide a reliable global automotive safety partner for the supply chain. Renesas has always put safety at the forefront of design during its long history of development; therefore , which is a natural next step in Renesas’ commitment to creating safe, cutting-edge, next-generation connected car solutions for customers in the automotive field.”

Renesas’ ISO 26262-compliant functional safety process has a long history; at the same time, Renesas is further strengthening its development process with a focus on safety issues to continue its excellence in building reliable systems. In 2019, Renesas’ industrial CSMS process was certified by T?V Rheinland to comply with the IEC 62443-4:2018 specification.

Building on these established processes, coupled with Renesas’ deep involvement in the development of the ISO/SAE 21434 standard, the company will continue to upgrade its in-vehicle CSMS processes to address the new requirements and expectations set forth by ISO/SAE 21434 and to strengthen an effective cybersecurity culture ; which includes establishing leadership roles for system security, hardware security, and software security to manage security-related development activities and create specific work products to confirm compliance with processes. Renesas has a long and rich experience in automotive-grade MCU and SoC development under the ISO 26262 standard, and we will further meet the needs of the cybersecurity market including ISO/SAE 21434.
