Block diagram

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 PN511.

transfer speeds above 424 kbit/s and digital signals to communicate to a secure smart

card IC.
