The Microchip Technology ATSHA204-TH-DA-T is a secure authentication and validation device designed for various applications including anti-clone protection, secure boot validation, and network access control. It integrates capabilities for both Host and Client operations, utilizing a superior SHA-256 Hash algorithm with MAC and HMAC options.
Key features include a 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, and 512 OTP bits for fixed information. It supports multiple I/O options, including a high-speed Single-Wire Interface and a 1MHz I2C interface.
Operating within a 2.0V to 5.5V supply voltage range and 1.8V to 5.5V communications range, the ATSHA204-TH-DA-T boasts a low sleep current of less than 150nA. It provides extended, multi-level hardware security. The component is available in an 8-lead TSSOP package suitable for surface mounting.
This device is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' and has been replaced by the ATSHA204A. It is suitable for applications requiring secure authentication and validation in networking and communications.
