1. Introduction

This document describes the NFC controller PN532. This document is a short form

version; for full specification refer to the product data sheet.

2. General description

The PN532 is a highly integrated transmission module for contactless communication at

13.56 MHZ including micro-controller functionality based on an 80C51 core. The

transmission module utilises an outstanding modulation and demodulation concept

completely integrated for different kinds of passive contactless communication methods

and protocols at 13.56 MHZ.

The PN532 support 4 different operating modes:

• Reader/writer mode supporting ISO 14443A / MIFARE

and FeliCa™ scheme

• ISO 14443B in reader/writer mode only.

• Card interface mode supporting ISO 14443A / MIFARE

and FeliCa™ scheme

• NFCIP-1 mode

Enabled in reader/ writer mode for ISO reader 14443A / MIFARE

and reader/writer mode

for ISO 14443B, the PN532’s internal transmitter part is able to drive a reader/writer

antenna designed to communicate with ISO14443A /MIFARE

and ISO14443B cards and

transponders without additional active circuitry.

The receiver part provides a robust and efficient implementation of a demodulation and

decoding circuitry for signals from ISO 14443A / MIFARE

and ISO 14443B compatible

cards and transponders. The digital part handles the complete ISO14443A framing and

error detection (Parity & CRC).

The PN532 supports MIFARE“ Classic (e.g. MIFARE

Standard) products. The PN532

supports contactless communication using MIFARE

Higher Baudrates up to 424kBaud in

both directions.

Enabled in the reader/ writer mode for FeliCa™, the PN532 transmission module supports

the FeliCa™ communication scheme. The receiver part provides a robust and efficient

implementation of the demodulation and decoding circuitry for FeliCa™ coded signals.

The digital part handles the FeliCa™ framing and error detection like CRC. The PN532

supports contactless communication using FeliCa™ Higher Baudrates up to 424

kbaud in

both directions.

PN532/C1 Philips Semiconductors NFC controller Enabled in card mode the PN532 transmission module is able to answer to a reader/writer command either acoording to FeliCa™ or ISO14443 A / MIFARE® card interface mode. The PN532 generates the digital load-modulated signals and in addition with an external circuit the answers can be send back to the reader/writer. A complete card functionality is only possible in combination with a secure memory IC.

PN532/C1 Philips Semiconductors NFC controller 9.1.4 NFCIP-1 MODE The NFCIP-1 communication differentiates between an active and a passive communication mode. • Active Communication Mode means both the initiator and the target are using their own RF field to transmit data • Passive Communication Mode means that the target answers to an initiator command in a load modulation scheme. The initiator is active in terms of generating the RF field. • Initiator: generates RF field @ 13.
