Nuvoton Technology Japan Achieves ISO/SAE 21434 Process Certification
Nuvoton Technology Corporation Japan (hereafter referred to as"Nuvoton") is the first Japanese semiconductor company* toreceive the ISO/SAE 21434 process certification from SGSTÜV Saar GmbH, a German certification body.

Toward the Realizationof a Safety andSecurity Automotive
Society*According to our research as of April 27, 2023

We have long been working to strengthen our security technology with the aim of " Realizea safe and happy society that is close to all people". In order to ensure that our customers
can use our automotive products and services with confidence, we have established aCyber Security Management System (CSMS) for automotive semiconductor products inaccordance with ISO/SAE 21434 "Road vehicle - Cybersecurity engineering" with thecooperation of SGS Japan Inc.
While connected cars, which have been on the rise in recent years, are expected toimprove convenience for users, the risk of being the victim of cyber-attacks such as cartheft, hijacking, and theft of personal information is also increased. The global automotive
industry has worked together to reduce this cybersecurity risk, establishing UN regulations(UNR-155/156) and establishing international standards (ISO/SAE 21434).
Cyber-attacks exploit vulnerabilities in the E/E (Electrical & Electronic) systems ofautomobiles, so the entire lifecycle of an automobile, from development, manufacturing,and use to disposal, as well as the supply chain of its components, must be managed toprevent vulnerabilities from being introduced. In addition, it is necessary to respond to newvulnerabilities caused by the evolution of attack methods.

As a supplier of automotive semiconductor products,
which are the core of automotive E/E systems, we will
provide our products to which the established CSMS has
been applied, and we will continue to contribute to therealization of a safety and security automotive society byacquiring TÜV product certification under ISO/SAE 21434
when necessary.
