The Renesas Security Mission

Renesas establishes and maintains dependable security foundations, building long-term trust in our products and our customer's solutions.



The Renesas Security Commitment

Renesas Electronics has been designing and producing microcomputers for secure MCUs for over ten years. With our commitment to continued investment in the expertise and equipment necessary for leading-edge new product development, Renesas is well-positioned to address the heightened need for security in today’s connected products.

Renesas secure MCUs have tamper-resistant designs, including features such as metal shields, irregular alignment and multi-layered wiring, security detectors, cryptographic coprocessors, and on-chip security logic. In order to help deal with a wide range of security threats, Renesas smartcard microcomputers include various advanced countermeasures against current analysis, physical analysis, failure analysis, and fault attacks.

For these reasons, our products have been adopted globally in various fields such as finance and mobile communications. This allows us to transfer advanced security techniques into the domains of automotive, industrial, and consumer electronics.
