MFRC523
Contactless reader IC
6. Block diagram
The analog interface manages 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
transfers to/from the host and the contactless UART.
Various host interfaces are implemented to meet different customer requirements.
