ISO 14443 Reader IC
Short From Specification Rev. 2.0 February 2002
MF RC531
1 INTRODUCTION
1.1 Scope
The MF RC531 is member of a new family of
highly integrated reader ICs for contactless
communication at 13.56 MHz. This reader IC
family utilises an outstanding modulation and
demodulation concept completely integrated for all
kinds of passive contactless communication
methods and protocols at 13.56 MHz. The MF
RC531 is pin- compatible to the MF RC500, the
MF RC530 and the SL RC400.
The MF RC531 supports all layers of the
ISO14443 including the type A and type B
communication scheme
The MF RC531 supports contactless
communication using MIFARE® Higher Baudrates.
The internal transmitter part is able to drive an
antenna designed for proximity operating distance
(up to 100 mm) directly without additional active
circuitry.
The receiver part provides a robust and efficient
implementation of a demodulation and decoding
circuitry for signals from ISO14443 compatible
transponders.
The digital part handles the complete ISO14443
framing and error detection (Parity & CRC).
Additionally it supports the fast MIFARE® Classic
security algorithm to authenticate MIFARE®
Classic (e.g. MIFARE® Standard, MIFARE® Light)
products.
A comfortable parallel interface, which can be
directly connected to any 8-bit µ-Processor gives
high flexibility for the reader/terminal design.
Additionally a SPI compatible interface is
supported.

1.3 Applications
The MF RC531 is tailored to fit the requirements
of various applications using contactless
communication based on ISO/IEC 14443 standard
where cost-effectiveness, small size, high
performance with a single voltage supply are
important.
