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 pincompatible 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.
