ArmorFlash is an ideal secure flash solution for embedded systems. It is built on top of Serial NOR flash by providing a secure ID, authentication, and an encrypted link to protect valuable data stored in it. ArmorFlash offers a physical unclonable function (PUF) that makes use of a semiconductor’s biometrics, which are characteristics derived from fabrication that can be used for encoding or identification. These solutions are available for the Renesas RA family of MCUs.
