AT90SP0801 Datasheet (ATMEL Corporation) - Secure Signature Generation Chip

AT90SP0801, Secure Signature Generation Chip

The AT90SP0801 is used to perform cryptographic operations, using asymmetric private keys stored in its internal EEPROM.

An arbitrary number of private keys can be stored externally and decrypted by the chip when required.

Communication to the system processor is via the SMBus.
