        簡單介紹
        POS機非接觸式芯片PN512 is the most broadly adopted NFC frontend - powering more than 10 billion NFC transactions per year. It is a highly integrated NFC frontend for co ntactless communication at 13.56MHz. This NFC frontendutilizes an outst anding modulation and demodula tion concept completely integrated for different kinds of contactl ess communication methods and protocols at 13.56M

        POS機非接觸式芯片

        Enabled in Reader/Writer mode for ISO
        /IEC14443A/MIFARE, the PN512?ˉs internal
        transmitter part is able to drive a reader/writer antenna designed to communicate with
        ISO/IEC14443A/ MIFARE cards and transponders
        without additional active circuitry. The
        receiver part provides a robust and effici
        ent implementation of a demodulation and
        decoding circuitry for signals from ISO/IEC14443A/MIFARE

        POS機非接觸式芯片 
        compatible cards and
        transponders. The digital part handles the complete ISO/IEC14443A framing and error
        detection (Parity and CRC).
        Enabled in Reader/Writer mode for FeliCa,
        the PN512 NFC frontendsupports the FeliCa
        communication scheme. The receiver part provides a robust and efficient implementation
        of the demodulation and decod
        ing circuitry for FeliCa coded signals. The digital part
        handles the FeliCa framing and
        error detection like CRC. The PN512 supports contactless
        communication using FeliCa Higher
         transfer speeds up to 424
        kbit/s in both directions.
        The PN512 supports all layers of the ISO/IEC14443B reader/writer communication
        scheme, given correct implementation of ad
        ditional components, like oscillator, power
        supply, coil etc. and provided that standardized protocols, e.g. like ISO/IEC14443-4
        and/or ISO/IEC14443B anticollisio
        n are correctly implemented.
        In Card Operation mode, the PN512 NFC frontend is able to answer to a reader/writer
        command either according to the FeliCa or
         ISO/IEC14443A/MIFARE card interface
        scheme. The PN512 generates the digital load modulated signals and in addition with an
        external circuit the answer can be sent back to the reader/writer. A complete card
        functionality is only possible in combination with a secure IC using the S
        2
        C interface.
