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.
The ATSHA204 is available in industry-standard SOT-3, SOIC-8, UDFN-8 and TSSOP-8 packages with either a single-wire or I2C interface.
Atmel has not yet released the datasheet for the ATSHA204; however, datasheets for related devices in the CryptoAuthentication family can be found here. The crypto portal provides valuable resources, including application notes, design guides, and software libraries to help developers integrate these devices into their projects.
