SHA105 is a cost-optimized security authentication IC produced by Microchip. TOPCHIP ELECTRONICS, which sells Microchip's full range of IC electronic components, provides you with an introduction, features, parameters and ordering models of SHA105.
Introduction to SHA105
SHA105 is a member of the CryptoAuthentication product family. The device provides 128-bit symmetric security for single-use and ecosystem control applications and is intended to be used as a companion device to microcontrollers from Microchip or other vendors. The device can be used in systems that require one-sided or mutual authentication. SHA105 acts as a host-side device in systems with mutual authentication. Consider using SHA104 as a client-side symmetric key on disposable or add-on systems.
