ISO 14443A Reader IC MF RC530

1 INTRODUCTION

1.1 Scope

The MF RC530 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
RC530 is pin- compatible to the MF RC500, the
MF RC531 and the SL RC400.

The MF RC530 supports all layers of the
ISO14443A communication scheme.
The MF RC530 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 ISO14443A compatible
transponders.
The digital part handles the complete ISO14443A
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.

2 BLOCK DIAGRAM

The block diagram shows the main internal parts
of the MF RC530.

The parallel µController interface automatically
detects the kind of 8 bit parallel interface
connected to it. It includes a comfortable bi­directional FIFO buffer and a configurable
interrupt output. This gives the flexibility to
connect a variety of µC, even low cost devices,
still meeting the requirements of high speed
contactless transactions.

Additionally a SPI compatible interface will be
supported. The MF RC530 acts as a slave during
the SPI communication. The SPI clock SCK has
to be generated by the master. The SPI interface
includes a comfortable bi-directional FIFO buffer.

The Data processing part performs parallel serial
conversion of the data. It supports framing
including CRC and parity generation / checking. It

operates in full transparent mode thus supporting
all layers of ISO 14443A.

The status and control part allows configuration of
the device to adapt to environmental influences
and to adjust to operate with best performance.

For communication with MIFARE® Classic
products like MIFARE® Standard or MIFARE

Light a high speed CRYPTO 1 stream cipher unit
and a secure non-volatile key memory is
implemented.

The analog circuit includes a transmitting part with
a very low impedance bridge driver output. This
allows an operating distance up to 100mm. The
receiver is able to detect and decode even very
weak responses. Due to a highly sophisticated
implementation the receiver is no longer a limiting
factor for the operating distance.
