Boost IoT Device Security with the Atmel ATECC508A CryptoAuthentication Device, Now at Mouser


Mouser Electronics, Inc., is now stocking the ATECC508A CryptoAuthentication device from Atmel, now a part of Microchip Technology. Delivering ultra-secure cryptographic elements that enable more secure connected systems, the ATECC508A 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.

The Atmel ATECC508A CryptoAuthentication device, now 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, Elliptic Curve Diffie–Hellman (ECDH) security protocol, and Elliptic Curve Digital Signature Algorithm (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 ATECC508A device is available in 8-pad UDFN, 8-lead SOIC, and 3-lead contact packages and delivers extremely low power consumption over a wide 2.0V to 5.5V supply voltage. The device integrates into a hardware design alongside the host microprocessor and interfaces directly to the host over the I2C bus. The ATECCC508A is compatible with any microprocessor or microcontroller including the Atmel SMART and Atmel AVR devices. The ATECC508A is supported by two development tools also available from Mouser: the CryptoAuth Xplained Pro add-on board and the CryptoAuthentication USB Dongle Demo-Evaluation Kit.
