The TA010 is a member of the CryptoAutomotive™ product family. The device is targeted for accessory ecosystem control applications and is intended to be used as a companion device with Microchip or other vendors’ microcontrollers. Consider implementing an TA100 in your host to perform the ECDSA P256 verify function of the signature your automotive electronic card would return. You could leverage that same TA100 for mutual authentication to an IoT cloud platform and add many more authentication use cases in your host.

The secure authentication IC is optimized to support the mandated authentication in Qi1.3 and Qi 2.0 from the Wireless Power Consortium (WPC).
