TrustME® 安全串行快閃記憶體W77Q系列符合共同準則EAL 2+ 安全認證等級的要求，為有限的儲存空間、輸出接腳和電源的操作系統提供一個安全儲存解決方案。
W77Q可望成為SPI NOR Flash裝置簡易隨插即用式的替代產品，相較標準型NOR快閃記憶體，W77Q可提高安全度、靈活性和其性能。亦能支援安全就地執行（XIP），是加密密鑰配置、管理和儲存、安全數據儲存、以及ㄧ般數據儲存的理想選擇。
W77Q產品特性具有先進的通信通道加密技術，並使用特定的密鑰為不同裝置符合個人化的需求，上鎖的加密讀取和寫入、數據完整性防護、安全即時線上(OTA)韌體更新、信任根(RoT)功能、安全讀取、寫入與擦除操作。
W77Q系列支援Single、Dual 和Quad SPI，以及QPI等操作模式，並可運行至133 MHz，可支援Dual Transfer Rate (DTR)且高達66 MHz。
