PN532 NFC Integrated Solution

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.

The PN532 supports the following host interfaces:

SPI
I²C
High Speed UART (HSU)

An embedded low-dropout voltage regulator allows the device to be connected directly to a battery. In addition, a power switch is included to supply power to a secure IC
