Contactless Reader IC

6. Block diagram

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

The contactless UART handles the protocol requirements for the communication schemes

in co-operation with the host. The comfortable FIFO buffer allows a fast and convenient

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

Various host interfaces are implemented to fulfil different customer requirements.
