The ATSHA204A-MAHCZ-T from Microchip Technology is a specialized integrated circuit designed for secure authentication and key storage. It utilizes a superior SHA-256 hash algorithm, offering Message Authentication Code (MAC) and Hash-Based Message Authentication Code (HMAC) options for robust security.
This device features protected hardware-based key storage with capacity for up to 16 keys and 4.5 kb of EEPROM for keys and data. It includes a high-quality internal Random Number Generator (RNG) and a guaranteed unique 72-bit serial number. The ATSHA204A-MAHCZ-T 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, it offers flexibility in system design. The chip consumes less than 150 nA in sleep mode. It is available in an 8-lead UDFN (2x3) package, suitable for surface mounting.
Key applications include secure download and boot, ecosystem control, anti-cloning, and message security, making it ideal for products requiring enhanced security features.
