ATAES132A
Description
The Atmel ATAES132A is a high-security, Serial Electrically-Erasable and Programmable
Read-Only Memory (EEPROM) providing both authentication and confidential nonvolatile
data storage capabilities. Access restrictions for the 16 user zones are independently
configured, and any key can be used with any zone. In addition, keys can be used for
standalone authentication. This flexibility permits the ATAES132A to be used in a wide
range of applications.
The AES-128 cryptographic engine operates in AES-CCM mode to provide authentication,
stored data encryption/decryption, and Message Authentication Codes. Data
encryption/decryption can be performed for internally stored data or for small external data
packets, depending upon the configuration. Data encrypted by one ATAES132A device can
be decrypted by another, and vice versa.
The ATAES132A pinout is compatible with standard SPI and I2C Serial EEPROMs to allow
placement on existing PC boards. The SPI and I2C instruction sets are identical to the Atmel
Serial EEPROMs. The extended security functions are accessed by sending command
packets to the ATAES132A using standard write instructions, and reading responses using
standard read instructions. The ATAES132A secure Serial EEPROM architecture allows it
to be inserted into existing applications.
The ATAES132A device incorporates multiple physical security mechanisms to prevent the
release of the internally stored secrets. Secure personalization features are provided to
facilitate third-party product manufacturing.
