Secure Flash memory offers end-to-end security for IoT devices

February 25, 2020 / Julien Happich

The W77Q provides hardware root-of-trust and secure, encrypted data-storage and data-transfer capabilities. By ensuring robust, end-to-end security in IoT devices it enables secure code updates, including over-the-air updates, via an end-to-end secure channel between an update authority and the W77Q even when the host processor or SoC has been compromised. It supports secure boot and root-of-trust, authenticated and encrypted data transfer between the Flash device and the host, secure Execute-in-Place (XiP) of boot and application code while supporting the key security functions of protection, detection and recovery.
