The ATSHA204A-SSHDA-B from Microchip Technology is a crypto element designed for secure authentication and data protection. It provides protected hardware-based key storage and supports superior SHA-256 hash algorithm operations, including Message Authentication Code (MAC) and Hash-Based Message Authentication Code (HMAC) options.
This device offers a 256-bit key length with storage for up to 16 keys and includes a guaranteed unique 72-bit serial number. It features an internal, high-quality Random Number Generator (RNG) and 4.5 kb of EEPROM for keys and data, along with 512 bits of One-Time Programmable (OTP) memory for fixed information.
Connectivity is provided through multiple I/O options, including a UART-compatible high-speed, single-wire interface and a 1 MHz I2C interface. The operating supply voltage ranges from 2.0V to 5.5V, with a communications voltage range of 1.8V to 5.5V. It consumes less than 150 nA in sleep mode.
The ATSHA204A-SSHDA-B is supplied in an 8-lead SOIC surface-mount package, making it suitable for applications requiring secure download and boot, ecosystem control, anti-cloning, and message security in networking and communications.
