1. General description

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

13.56 MHz based on the 80C51 microcontroller core. It supports 6 different operating

modes:

• ISO/IEC 14443A/MIFARE Reader/Writer

• FeliCa Reader/Writer

• ISO/IEC 14443B Reader/Writer

• ISO/IEC 14443A/MIFARE Card MIFARE 1 KB or MIFARE 4 KB emulation

• FeliCa Card emulation

• ISO/IEC 18092, ECMA 340 Peer-to-Peer

The PN532 implements a demodulator and decoder for signals from

ISO/IEC 14443A/MIFARE compatible cards and transponders. The PN532 handles the

complete ISO/IEC 14443A framing and error detection (Parity & CRC).

The PN532 supports MIFARE 1 KB or MIFARE 4 KB emulation products. The PN532

supports contactless communication using MIFARE Higher transfer speeds up to

424 kbit/s in both directions.

The PN532 can demodulate and decode FeliCa coded signals. The PN532 handles the

FeliCa framing and error detection. The PN532 supports contactless communication

using FeliCa Higher transfer speeds up to 424 kbit/s in both directions.

The PN532 supports layers 2 and 3 of the ISO/IEC 14443 B Reader/Writer

communication scheme, except anticollision. This must be implemented in ﬁrmware as

well as upper layers.

In card emulation mode, the PN532 is able to answer to a Reader/Writer command either

according to the FeliCa or ISO/IEC 14443A/MIFARE card interface scheme. The PN532

generates the load modulation signals, either from its transmitter or from the LOADMOD

pin driving an external active circuit. A complete secure card functionality is only possible

in combination with a secure IC using the NFC-WI/S

C interface.

Compliant to ECMA 340 and ISO/IEC 18092 NFCIP-1 Passive and Active communication

modes, the PN532 offers the possibility to communicate to another NFCIP-1 compliant

device, at transfer speeds up to 424 kbit/s.The PN532 handles the complete NFCIP-1

framing and error detection.

The PN532 transceiver can be connected to an external antenna for Reader/Writer or

Card/PICC modes, without any additional active component.
