Secure High-Density Flash Memories

02 April 2024

The TrustME W77Q family of flash data storage devices from Winbond has been expanded.

256Mbit, 512Mbit and 1Gbit capacity options are now encompassed. Each of these units, which are targeted at edge-located IoT hardware, has high-performance 166MHz quad-SPI interfacing. They leverage a sophisticated Leighton-Micali signature (LMS) algorithm implementation for post quantum cryptography (PQC). Extended replay protected monotonic counters (RPMCs) are supported. Both the 512Mbit and 1Gbit units allow simultaneous read and write operation to be conducted. Superior authentication protocols have been incorporated too.
