ATSHA204A-STUCZ-T Description

Short technical summary and product information.

The ATSHA204A-STUCZ-T from Microchip Technology is a crypto element designed for secure authentication and data protection. It provides protected hardware-based key storage and utilizes the superior SHA-256 hash algorithm with options for Message Authentication Code (MAC) and Hash-Based Message Authentication Code (HMAC).

 

This device supports secure symmetric authentication for both host and client operations. It offers a best-in-class 256-bit key length with storage for up to 16 keys. A guaranteed unique 72-bit serial number and an internal, high-quality Random Number Generator (RNG) are included for enhanced security. The device features 4.5 kb of EEPROM for keys and data, and 512 bits of One-Time Programmable (OTP) memory for fixed information.

 

Connectivity options include 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. The ATSHA204A-STUCZ-T consumes less than 150 nA in sleep mode.

 

Applications for this security IC include secure download and boot, ecosystem control, anti-cloning, and message security. It is available in an 8-lead SOIC, 8-lead TSSOP, 3-lead SOT23, 8-pad UDFN, and 3-lead CONTACT packages. The operating temperature range is -40 C to +85 C.
