TrustME® 安全串行闪存W77Q系列符合共同准则EAL 2+ 安全认证等级的要求，为有限的储存空间丶输出接脚和电源的操作系统提供一个安全储存解决方案。
W77Q可望成为SPI NOR Flash装置简易随插即用式的替代产品，相较标准型NOR闪存，W77Q可提高安全度丶灵活性和其性能。亦能支援安全就地执行（XIP），是加密密钥配置丶管理和储存丶安全数据储存丶以及ㄧ般数据储存的理想选择。
W77Q产品特性具有先进的通信通道加密技术，并使用特定的密钥为不同装置符合个人化的需求，上锁的加密读取和写入丶数据完整性防护丶安全即时线上(OTA)固件更新丶信任根(RoT)功能丶安全读取丶写入与擦除操作。
W77Q系列支援Single丶Dual 和Quad SPI，以及QPI等操作模式，并可运行至133 MHz，可支援Dual Transfer Rate (DTR)且高达66 MHz。
