Secure Flash for Resilient Embedded Systems

Firmware tampering is a fast and effective way to take down a connected device. Winbond’s TrustME® W77Q Secure Flash offers a practical way to safeguard firmware for developers building resilient systems. Built-in protection, tamper detection, and recovery features help secure critical code with minimal impact on performance or board space.

W77Q meets NIST SP 800-193 recommendations and integrates features like secure boot, cryptographic verification, and rollback prevention directly into industry-standard Serial NOR Flash. It also supports post-quantum cryptography (LMS), so you’re not building on algorithms destined to be broken.

This is not a bolt-on security module. W77Q is fully pin-compatible with conventional NOR Flash, making it a true drop-in option. Use it first as standard flash, then enable layered security through software updates—ideal for phased rollouts and agile design cycles. Winbond’s royalty-free SDKs and reference implementations help get working prototypes up and running faster.

Available from 16Mb to 1Gb, W77Q suits a wide range of applications—from edge devices and consumer gear to automotive-grade systems where reliable OTA updates and fallback firmware images are essential.
