... Philips Semiconductors PN531 1.2 Application The PN531 is tailored to fulfil the requirements of various applications using contactless communication based on the ECMA340 (NFC IP-1) Interface and protocol standard, the ISO14443A reader and FeliCa reader protocol. NFC IP-1 is also standardised in ISO/IEC 18092. Compatible to current RFID infrastructure the NFC technology offers a new direct communication link between two NFC enhanced devices ...

... The RF level detector detects the presence of an external RF field at 13.56 MHz. The mode detector detects a MIFARE®, FeliCa the internal receiver to demodulate signals that are sent to the PN531. The integrated contactless UART and the firmware handle the protocol requirements for the communication schemes including the RF based protocols as well as the protocols for host communication ...
