The ATSHA204A-STUCZ-T from Microchip Technology is a specialized integrated circuit designed for authentication and security applications. It features a crypto element with protected hardware-based key storage, supporting secure symmetric authentication for host and client operations.
This device utilizes the SHA-256 hash algorithm with options for Message Authentication Code (MAC) and Hash-Based Message Authentication Code (HMAC). It offers a 256-bit key length and storage for up to 16 keys, along with a guaranteed unique 72-bit serial number and an internal high-quality Random Number Generator (RNG).
Key electrical specifications include a supply voltage range of 2.0V to 5.5V and a communications voltage range of 1.8V to 5.5V. It consumes less than 150 nA in sleep mode. The chip provides 4.5 kb of EEPROM for keys and data, and 512 bits of One-Time Programmable (OTP) memory for fixed information.
Available I/O options include a UART-compatible high-speed, single-wire interface and a 1 MHz I2C interface. The ATSHA204A-STUCZ-T is supplied in a 3-lead SOT-23 surface mount package. Its applications include secure download and boot, ecosystem control, anti-cloning, and message security.
