The device includes several security features, such as optimized key storage and authentication, ECDH security protocol, and ECDSA signature verification authentication. It also features a 256-bit SHA/HMAC hardware engine, a 10.5 kbit EEPROM for secret and private keys, and a guaranteed 72-bit unique ID. The ATECC608B is currently available in 8-pad UDFN, 8-terminal SOIC, and 3-terminal contact pack versions, and offers extremely low power consumption with a wide supply voltage range of 2.0 to 5.5 V. With ultra-secure cryptographic elements that enable more secure connected systems, the ATECC608B is ideal for various Internet of Things (IoT) applications in home automation, industrial networks, IoT node and ID security, message security and authentication, medical devices, ecosystem control, and cloning protection.
