1 Introduction
The ATECC608C is a member of the Microchip CryptoAuthentication™ family of 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 that of 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 they move to the ATECC608C. For designs not planned to be upgraded, it is recommended that customers review their designs to see if they would benefit from the enhanced security of the ATECC608C. For assistance with migrating a design to the ATECC608C, see the Migrations References section.
