CryptoAuthentication Device for Secure Connected Systems

Mouser Electronics is now stocking the ATECC608B CryptoAuthentication device from Microchip Technology. Delivering ultra-secure cryptographic elements that enable more secure connected systems, the ATECC608B is ideal for a variety of Internet of Things (IoT) applications in the areas of home automation, industrial networking, IoT node security and ID, message security and authentication, medical devices, ecosystem control, and anti-cloning.

Microchip ATECC608B CryptoAuthentication device

The Microchip ATECC608B CryptoAuthentication device, available from Mouser Electronics, can function as either a device pre-loaded with cryptographic keys, keeping the keys securely stored within embedded and IoT devices, or as a cryptographic co-processor, executing strong cryptographic algorithms without burdening the resources of the host microprocessor or microcontroller. The device includes several security features, including optimized key storage and authentication functionality, ECDH security protocol, and ECDSA sign-verify authentication. The device also includes 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 device is currently available in 8-pad UDFN, 8-lead SOIC and 3-lead contact package options and delivers extremely low power consumption over a wide 2.0 V to 5.5 V supply voltage. The device integrates into a hardware design alongside the host microprocessor and interfaces directly to the host over the I²C bus.
