The Microchip Technology ATECC108A-SSHCZ-B is a CryptoAuthentication device with secure hardware-based key storage. It performs high-speed public key algorithms, including ECDSA and SHA-256 hash algorithm with HMAC option. This device supports NIST Standard P256, B283, and K283 elliptic curves, with key lengths of 256-bit and 283-bit. It offers storage for up to 16 keys and 10Kb of EEPROM memory for keys, certificates, and data.
Designed for applications such as secure download and boot, ecosystem control, message security, and anti-cloning, the ATECC108A-SSHCZ-B operates within a supply voltage range of 2.0V to 5.5V, with IO levels from 1.8V to 5.5V. It features a low sleep current of less than 150nA. The device is available in an 8-lead SOIC package and is suitable for surface mounting.
Key features include a guaranteed unique 72-bit serial number, an internal FIPS random number generator, and multiple I/O options such as a high-speed single-pin interface and a 1MHz standard I2C interface. The ATECC108A-SSHCZ-B is designed to ensure that devices and code are real, untampered, and confidential, making it ideal for network and IoT node protection, anti-counterfeiting, and protecting firmware or media.
