The ATSHA204A-SSHDA-B from Microchip Technology is a CryptoAuthentication security element designed for secure operations. It provides protected hardware-based key storage and supports secure symmetric authentication for host and client operations. The device utilizes the superior SHA-256 hash algorithm, offering Message Authentication Code (MAC) and Hash-Based Message Authentication Code (HMAC) options.
Key features include storage for up to 16 keys with a 256-bit key length, a guaranteed unique 72-bit serial number, and an internal high-quality Random Number Generator (RNG). It is equipped with 4.5 kb of EEPROM for keys and data, and 512 bits of One-Time Programmable (OTP) memory for fixed information. The device supports multiple I/O options, including a UART-compatible High-Speed, Single-Wire Interface and a 1 MHz I2C interface.
With a supply voltage range of 2.0V to 5.5V and a communications voltage range of 1.8V to 5.5V, the ATSHA204A-SSHDA-B consumes less than 150 nA in sleep mode. It is available in an 8-lead SOIC package, suitable for surface mounting. Applications include secure download and boot, ecosystem control, anti-cloning, and message security.
