The W25R-JW series is a 1.8V RPMC Authentication Flash featuring a standard HMAC-SHA-256 crypto accelerator and four independent Monotonic Flash Counters, each HMAC-signed with its own secret key. Systems using these counters can verify the integrity and authenticity of counter values and attach secure timestamps to transmitted information, providing strong protection against replay attacks. With these capabilities, the W25R-JV series enables system designers to reinforce code and data storage security and address the growing need for multi-layered authenticity in emerging IoT applications.
