Serial I/O Peripherals
Fast, Secure, and Cost Effective Symmetric Authentication. The Microchip SHA-based CryptoAuthentication crypto element devices have been architected to provide flexible user-configured security to enable a wide range of authentication models. The ATSHA204A is the first device in the SHA device group. The ATECC108A and ATECC508A are supersets of the ATSHA204A and thus upward compatible. As with all CryptoAuthentication devices, the ATSHA204A is easy to design in with no crypto expertise required. Secure Hash Algorithm (SHA) algorithms are widely used in most cryptographic systems and remain an important component in most modern authentication protocols. These devices support the SHA-256 standard.
