AT88SC018 Datasheet PDF - Atmel Corporation

Product Overview
The CryptoCompanion™ Chip is designed as the mate to Atmel’s CryptoRF and CryptoMemory chips, collectively referred to in the remainder of this document as CRF.
CryptoCompanion makes extensive use of the SHA-1 hash algorithm as specified in
http://www.itl.nist.gov/fipspubs/fip180-1.htm and elsewhere. In this document, the nomenclature SHA-1(a, b, c) means to concatenate a, b & c in that order and then pad them to a block size of 64 bytes before computing the digest. CryptoCompanion generates SHA-1 digests of single round datasets at a time.
