Mature product, not recommended for new designs. Replaced by ATSHA204.

Authentication chip that securely authenticates an item to which it is attached. The device can also be used to exchange session keys with some remote entity so that the system microprocessor can securely encrypt and decrypt data. Each chip contains a pre-programmed serial number that is guaranteed to be unique. The device has been designed to permit secure personalization so that third parties can build devices containing an OEM secret without concern for the theft of that secret. The device is the first small standard product to implement the SHA-256 hash algorithm, which renders exhaustive attacks impossible.
