Atmel Axxx Series CryptoAuthenication ChipsThe Atmel AT88SA1xx CryptoAuthentication™ IC family is a robust solution for any system design that requires protection from clones. The Atmel AT88SA10xx Battery Authentication Chip is a small CryptoAuthentication chip that can be used to validate battery packs and other replaceable items containing a power source. The AT88SA10xx uses the industry leading SHA-256 hash algorithm to provide the ultimate level of security. The Atmel ATSHA10xx Product Authentication Chip is a CryptoAuthentication IC designed to securely authenticate an item to which it is attached.The Atmel® ATSHA204 is the first member of the CryptoAuthentication™ family of secure authentication ICs to integrate the SHA-256 hash algorithm with a 4.5-Kbit EEPROM, providing robust hardware authentication and secure key/data storage at a very cost-effective price. With the ATSHA204, developers can easily implement secure authentication and validation of physical or logical elements in virtually all microprocessor-based systems using the straightforward, 256-bit challenge/response protocol.
