Description

The Atmel

read only memory (EEPROM) providing both authentication and confidential nonvolatile

data storage capabilities. Access restrictions for the sixteen user zones are independently

configured, which any key can be used with any zone. Keys can also be used for stand-

alone authentication. This flexibility permits ATAES132 to be used in a wide range of

applications.

The Atmel AES-128 cryptographic engine operates in the AES-CCM mode to provide

authentication, stored data encryption/decryption, and message authentication codes.

Both internally stored data and/or small external data can be protected by the ATAES132

device.

The ATAES132 pinout is compatible with the standard SPI and I

allow placement on existing PC boards. The SPI and I

the Atmel Serial EEPROM. The extended security functions are accessed by sending

command packets to the ATAES132 using standard write instructions, and reading

32Kbits of standard Serial EEPROM user memory
