ATECC608A-SSHDA-B

ATECC608A-SSHDA-B is a CryptoAuthentication™ device. It is a Cryptographic co-processor with secure hardware-based key storage which has protected storage for up to 16 keys, certificates, or data. It includes an EEPROM array which can be used for storage of up to 16 keys, certificates, miscellaneous read/write, read-only or secret data, consumption logging, and security configurations. Access to the various sections of memory can be restricted in a variety of ways and then the configuration can be locked to prevent changes. Access to the device is made through a standard I2C Interface at speeds of up to 1Mb/s. The interface is compatible with standard serial EEPROM I2C interface specifications. Typical applications are IoT network endpoint key management and exchange, encryption for small messages and PII data, secure boot and protected download, ecosystem control, and anti-cloning.
