ATECC608B-SSHDA-B Interface Type, Microchip ATECC608B-SSHDA-B 8-Pin Crypto Authentication IC SOIC

The Microchip ATECC608B series high-security cryptographic device combine world-class, hardware-based key storage with hardware cryptographic accelerators to implement various authentication and encryption protocols. It provides security enhancements over that of the ATECC608A, while providing complete backwards compatibility. All configuration settings, commands, packages and functionality of the ATECC608A are still available in the ATECC608B, making migration from the ATECC608A a simple process.
