MICROCHIP AT88SC018-SU-CM

The CryptoCompanion™ Chip is designed as the mate to Atmel’s CryptoRF and CryptoMemory chips. It makes extensive use of the SHA - 1 hash algorithm. It stores secrets in an obscured way in nonvolatile memory and contains circuitry for authentication, password and encryption/decryption functions. It includes a general - purpose cryptographic quality random number generator for a mutual authentication process. Benefits include keeping core secrets confidential, flexible system implementation, multiple setup options, hardware encryption engines, strong security for global secrets, robust random number generation, secure EEPROM storage, potential BOM reduction, and being easy to use.
