COMPANY PUBLIC
The analog interface handles the modulation and demodulation of the analog signals
according to the Card Receiving mode, Reader/Writer mode and NFCIP-1 mode
communication scheme.
The RF level detector detects the presence of an external RF-field delivered by the
antenna to the RX pin.
The Data mode detector detects a MIFARE, FeliCa or NFCIP-1 mode in order to prepare
the internal receiver to demodulate signals, which are sent to the PN512.
The communication (S
transfer speeds above 424 kbit/s and digital signals to communicate to a secure IC.
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.
