    Hello Eric,

    I'm glad to read that the customer is interested in the TRF7970A device. Please refer tot he datasheet for the supported protocols and features. Microsoft USBCCID is not supported natively. The TRF7970A is an RF device, which can handle the RF protocols. It needs a controller device connected via SPI or parallel interface. The controller device would be the next level layer to provide USBCCID connectivity.

    Best regards,

    Andreas.
