Name: ECC204-SSVDA-T
Brand: Microchip
SKU: ECC204-SSVDA-T

The ECC204 is a member of the 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. The ECC204 will perform an ECDSA sign (not verify) and a SHA256 HMAC operation.

Consider implementing an ATECC608 in your host to perform the ECDSA P256 verify function of the signature your disposable or accessory would return. You could leverage that same ATECC608 for mutual authentication to an IoT cloud platform
