W77Q Secure Flash Memory

The W77Q (32 Mbit) TrustME® Secure Serial Flash memory provides a secure storage solution for systems with limited space, pins and power, that meets Common Criteria EAL2 Security Certification requirements.

The W77Q 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 104 MHz. Dual Transfer Rate (DTR) is supported at rates up to 66 MHz.
