W77Q Secure Flash Memory
The W77Q TrustME® Secure Flash memory provides a secure storage solution for systems with limited space, pins and power, that meets Common Criteria EAL 2+ Security Certification requirements.
Winbond's W77Q Secure Flash memory is a drop-in replacement for standard Serial NOR Flash devices, offering security, flexibility, and performance well beyond ordinary NOR Flash devices. It is ideal for secure code storage with support for secure eXecute In Place (XIP), cryptographic key distribution, management and storage, secure data storage, and general data storage.
The W77Q features sophisticated cryptographic encryption of the communication channel, personalization of each device with unique keys, cryptographic read and write locks, protection of data integrity, secure over-the-air (OTA) firmware update, RoT functions, secure read, write and erase operations.
The W77Q series supports Single, Dual and Quad SPI as well as QPI modes of operation, running at up to 133 MHz. Dual Transfer Rate (DTR) is supported at rates up to 66 MHz.
Serial SPI NOR Flash based on the popular W25Q family Advanced security features： Root of trust and secure boot Secure Over-The-Air firmware update Resilience：Protection, detection and recovery Secure data storage
Design is based on pure digital logic, no integrated MCU Optimized for cost sensitive platforms Certified secure memory=Trusted and Proven Solution!
