Microchip Technology ECC204 Secure Authentication IC

Microchip Technology ECC204 Secure Authentication IC is a member of the Microchip Technology Inc. CryptoAuthentication™ product family. The device is targeted for disposable and ecosystem control applications and is intended to be used as a companion device with Microchip or other vendors’ microcontrollers. Consider implementing an ATECC608 in the user’s host to perform the ECDSA P256 to verify the function of the signature the user’s disposable or accessory would return. The user could leverage that same ATECC608 for mutual authentication to an IoT cloud platform.
