The ECC204 TrustFLEX WPC is a member of the CryptoAuthentication™ product family. The device is targeted for Qi 1.3 and Qi 2.0 wireless charger and is intended to be used as a companion device with Microchip or other vendors’ microcontrollers. Consider implementing an ATECC608 TrustFLEX WPC if you need to add more use cases than the basic Qi 1.3 and Qi 2.0 mandated authentication by the WPC Qi 1.3 and Qi 2.0 specification.
