The ATAES132A crypto element with hardware-based key storage is a very fast high-security serial 32K EEPROM device that enables authentication and confidential nonvolatile data storage. It is a direct drop-in for industry standard Serial EEPROMS, and supports the Advanced Encryption Standard (AES) cryptography standard.

The AES-128 cryptographic engine operates in AES-CCM mode to provide authentication, stored data encryption/decryption, and Message Authentication Codes (MACs). 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. Extended security functions are accessed by sending command packets to the ATAES132 using standard write instructions and reading responses using standard read instructions. The device incorporates multiple physical security mechanisms to prevent release of the internally stored secrets.

The device’s secure Serial EEPROM architecture and packages compatible with standard SPI and I²C EEPROM footprints allow insertion into many existing Serial EEPROM applications. Like all Atmel CryptoAuthentication devices the ATAES132A stores keys and other secret data in hardware protected by a range of physical and cryptographic countermeasures, making it far more secure than software or unprotected hardware storage mechanisms.
