Microchip Technology ATECC608C CryptoAuthentication™ ICs
Microchip Technology ATECC608C CryptoAuthentication™ ICs are high-security cryptographic devices, which combine world-class, hardware-based key storage with hardware cryptographic accelerators to implement various authentication and encryption protocols. The ATECC608C provides security enhancements over the ATECC608B, while providing backwards compatibility. All configuration settings, commands, packages, and functionality of the ATECC608B are still available in the ATECC608C, making migration from the ATECC608B a simple process. For new designs, it is recommended that customers start directly with the ATECC608C device. For designs that are being upgraded and currently use the ATECC508A, ATECC608A, or ATECC608B, it is recommended that the user move to the Microchip Technology ATECC608C. For designs not planned to be upgraded, it is recommended that customers review designs to see if the user would benefit from the enhanced security of the ATECC608C.
