1 INTRODUCTION
1.1 Scope
The PN531 is a highly integrated transmission module for contactless communication at 13.56 MHz including
µ-controller functionality based on an 80C51 core with 32 kbyte of ROM and 1 kbyte of RAM. This µc-based
transmission module combines an outstanding modulation and demodulation concept completely integrated
for different kinds of contactless communication methods and protocols at 13.56 MHz with an easy to use
firmware for the different supported modes and the required host interfaces.
The embedded firmware handles the ISO 14443A and MIFARE
FeliCa
Furthermore the embedded firmware and the internal hardware support the handling and the host protocols
for the different interfaces as

In reader/ writer mode the PN531’s internal transmitter part is able to drive a reader/writer antenna designed
to communicate with ISO14443A /MIFARE
circuitry. The receiver part provides a robust and efficient implementation of a demodulation and decoding
circuitry for signals from ISO14443A compatible cards and transponders. The digital part handles the
complete ISO14443A framing and error detection (Parity & CRC).

The PN531 offers the possibility to directly communicate with several NFC enabled devices in the NFC IP-1
mode. The NFC IP-1 mode offers different baudrates up to 424kbit/s. The PN531 handles the complete NFC
framing and error detection.
