Description

The AT88SA102S-TSU-DF-T is a member of the CryptoAuthentication family of chips, which are cost-effective authentication devices that implement the SHA-256 hash algorithm. This algorithm provides advanced security and renders exhaustive attacks impossible. The AT88SA10HS host version of the chip can validate the response from the SHA-256 engine within an authentic CryptoAuthentication client, even if the response includes the client's serial number. For more detailed information on the cryptographic protocols and usage models, please refer to the "AT88SA100S" and "AT88SA102S" datasheets and application notes dedicated to this product family.
