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 Classic 1K or MIFARE Classic 4K card
emulation mode
• 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 Classic 1K or MIFARE Classic 4K card emulation mode.
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/S2C 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.
