PN531
μC based Transmission module
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
reader protocol as well as the basic
FeliCa
TM
reader protocol and the complete NFC IP-1 protocol.
Furthermore the embedded firmware and the internal hardware support the handling and the host protocols
for the different interfaces as
USB 2.0
I2C
SPI and
Serial UART
The PN531 supports 3 different operating modes
Reader/writer mode for FeliCa
TM
and ISO14443A cards
Supports Card interface mode for FeliCa
TM
and ISO14443A/MIFARE
in combination with secure μC
NFC IP-1 mode
In reader/ writer mode the PN531’s internal transmitter part is able to drive a reader/writer antenna designed
to communicate with ISO14443A /MIFARE
or FeliCa
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 ISO14443A compatible cards and transponders. The digital part handles the
complete ISO14443A framing and error detection (Parity & CRC).
The PN531 supports MIFARE
Classic (e.g. MIFARE
Standard) products. The PN531 supports contactless
communication using MIFARE
Higher Baudrates up to 424kbit/s in both directions. In the reader/ writer
mode the PN531 transmission module supports the FeliCa
TM
communication scheme. The receiver part
provides a robust and efficient implementation of the demodulation and decoding circuitry for FeliCa
TM
coded
signals. The digital part handles the FeliCa
framing and error detection like CRC.
The PN531 supports contactless communication using FeliCa
TM
Higher Baudrates up to 424kbit/s in both
directions.
In card mode the PN531 is able to answer a reader/writer command either in FeliCa
TM
or
ISO14443A/MIFARE
card mode. The PN531 generates the proper digital load modulated signals and with
an external circuit, can respond to commands sent by the reader/writer.
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.
