W77Q Secure Flash Memory

Winbond’s 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.

W25Q NOR Flash Drop-in Replacement with Advanced Security

The W77Q Secure Flash memory is a W25Q NOR Flash drop-in replacement, offering advanced security, flexibility, high reliability, and performance well beyond ordinary NOR Flash devices. The W77Q series provides substantial levels of security as defined by various Cybersecurity regulations, which are optimized for consumer IoT, Industrial IoT, critical infrastructure equipment, MFP, Industrial PC, and server applications.

PQC Support and Secure Supply Chain Management

The W77Q series in densities of 256Mb, 512Mb, and 1Gb are the cutting-edge technology, supporting asymmetric key cryptography algorithm and enabling devices to facilitate both Secure OTA with asymmetric PQC signatures and Secure Supply chain via LMS-OTS (NIST 800-208). Winbond is proud to be the first memory vendor to integrate PQC, meeting the requirements of the emerging regulations and setting a new standard in the industry. These devices are optimally designed for applications in Industrial IoT, networking, servers, and critical infrastructure applications.

These W77Q devices support high-performance Quad-SPI at 166MHz2), extended Replay Protected Monotonic Counters (RPMC) with 8 counters for PC-based implementation. The 512Mb and 1Gb devices enable simultaneous read and write options enhancing operational efficiency for software OTA operation.
