Atmel CryptoMemory

The World’s Only Secure Serial EEPROM

Atmel® CryptoMemory® cryptographic security

ICs offer a cost-efficient, high-security solution

for any application requiring authentication, data

protection or secure storage.

A cryptographic algorithm encrypts data and

passwords, generates Message Authentication

Codes (MAC) thereby providing a secure

place where information remains safe, even

under attack. CryptoMemory is the only family

of secure memory devices in the industry with

mutual authentication between device and host,

plus data encryption. Both synchronous (2-

wire) and asynchronous (ISO7816) protocols

are available.
