Atmel AT88SC0104C‑AT88SC25616C CryptoMemory Secure Serial ICs Handbook
The CryptoMemory family provides secure serial EEPROM storage for sensitive data in embedded systems. It offers memory densities from 1 Kbit up to 256 Kbits and uses a 2‑wire serial interface compatible with up to 1.5 MHz operation.
Key features include dynamic mutual authentication, encrypted passwords with attempt counters, stream encryption, and a set of 15 commands. The devices are supplied in standard 8‑lead SOIC, PDIP, and LAP packages and share the same pinout as Atmel’s AT24Cxx EEPROMs, simplifying hardware and software integration.
