DS2476 EVALUATION KIT AVAILABLE DeepCover Secure Coprocessor General Description The DS2476 is a DeepCover® secure ECDSA and HMAC SHA-256 coprocessor companion to the DS28C36. The coprocessor can compute any required HMACs or ECDSA signatures to do any operation on the DS28C36. The DS2476 provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware implemented crypto engines, the device integrates a FIPS/NIST true random number generator (RNG), 8Kb of secured EEPROM, a decrement-only counter, two pins of configurable GPIO, and a unique 64-bit ROM identification number (ROM ID).
