The new CryptoMemory family of devices in plastic packages provides secure serial EEPROM storage for sensitive information within an embedded system.
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.
