Short form data sheet
9.1.1 Simplify block diagram
9.1.2 Feature list
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
prepare the internal receiver to demodulate signals, which are sent to the PN512.
The communication (S2C) interface provides digital signals to support communication for
transfer speeds above 424 kbit/s and digital signals to communicate to a secure core IC.
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.
