Product short 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 PN511.
The communication (S
