Atmel today announced the release of the ATSHA204 the first turnkey, optimized authentication device to include a 4.5Kbit EEPROM and a hardware SHA-256 accelerator. Fully tested ASF software libraries are available for Atmel AVR® and ARM®-based microcontrollers and are integrated within the new AVR Studio® 5. Contemplated uses include industrial, consumer, energy metering, home automation, computing and medical applications. An abstract detailing CryptoAuthentication uses is available.
