Product data sheet
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 handles the protocol requirements for the communication schemes
in co-operation with the host controller. The comfortable FIFO-buffer allows a fast and
convenient data transfer from the host controller to the contactless UART and vice versa.
Various host controller interfaces are implemented to fulfill different customer
requirements.
