6. Block diagram

The analog interface handles the modulation and demodulation of the analog signals.

The contactless UART manages the protocol requirements for the communication

protocols in cooperation with the host. The FIFO buffer ensures fast and convenient data

transfer to and from the host and the contactless UART and vice versa.

Various host interfaces are implemented to meet different customer requirements.
