Mouser now stocks the Microchip Technology ATECC608B CryptoAuthentication device. Supplying ultra-secure cryptographic elements that allow more secure connected systems, the device is excellent for various IoT applications in home automation, IoT node security and ID, industrial networking, message security and authentication, medical devices, ecosystem control, and anti-cloning.
The CryptoAuthentication device can function as a device pre-loaded with cryptographic keys, keeping the keys securely stored in embedded and IoT devices, or as a cryptographic co-processor, executing strong cryptographic algorithms with no burden on the resources of the host microprocessor or microcontroller. The device incorporates several security features, including optimised key storage and authentication functionality, ECDH security protocol, and ECDSA sign-verify authentication. The device includes a 256-bit SHA/HMAC hardware engine, a 10.5kbit EEPROM for secret and private keys, and a guaranteed 72-bit unique ID.
The device is currently offered in eight-pad UDFN, eight-lead SOIC and three-lead contact package options and provides extremely low power consumption over a wide 2V to 5.5V supply voltage. The device combines into a hardware design alongside the host microprocessor and interfaces straight to the host over the I²C bus.
