The Microchip Technology ATSHA204-SH-DA-B is a secure authentication and validation device. It integrates capabilities for both Host and Client operations, utilizing a superior SHA-256 Hash algorithm with Message Authentication Code (MAC) and Hash-Based Message Authentication Code (HMAC) options.
Key features include a best-in-class 256-bit key length with storage for up to 16 keys, a guaranteed unique 72-bit serial number, and an internal Random Number Generator (RNG). The device offers 4.5Kb of EEPROM for keys and data, along with 512 OTP bits for fixed information. It supports multiple I/O options, including a high-speed single-wire interface and a 1MHz I2C interface.
This authentication chip operates within a supply voltage range of 2.0V to 5.5V for power and 1.8V to 5.5V for communications, with a low sleep current of less than 150nA. It provides extended, multi-level hardware security.
The ATSHA204-SH-DA-B is available in an 8-lead SOIC package, suitable for surface mounting. Applications include anti-clone protection, secure boot validation, software anti-piracy, network and computer access control, and key exchange for encrypted downloads.
