Microchip Technology, Inc. Specialized ICs AT88SA10HS-TSU-T

The AT88SA10HS-TSU-T is a host security chip from the Atmel CryptoAuthentication family, designed for secure key storage and authentication applications. It features a SHA-256 hash algorithm, ensuring robust security with a guaranteed unique 48-bit serial number. The chip operates within a supply voltage range of 2.7V to 5.25V and supports a communications voltage of 1.8V to 5.5V, making it versatile for various applications. This device is suitable for use in consumable device authentication, network access control, and anti-clone authentication for daughter cards. It incorporates a high-speed single-wire interface and has a low sleep current of less than 150nA, contributing to energy efficiency. The AT88SA10HS-TSU-T is packaged in a 3-pin SOT-23 or 8-lead SOIC format and is compliant with RoHS standards. However, it is important to note that this part is not recommended for new designs and has been replaced by the ATSHA204, indicating that engineers should consider alternative options for future projects.
