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 (R) 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). (R) Additionally it supports the fast MIFARE Classic security algorithm to authenticate MIFARE (R) (R) (R) Classic (e.g. MIFARE Standard, MIFARE Light) products. A comfortable parallel interface, which can be directly connected to any 8-bit -Processor gives high flexibility for the reader/terminal design.

MF RC531
2 BLOCK DIAGRAM The block diagram shows the main internal parts of the MF RC531. The parallel Controller 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 C, even low cost devices, still meeting the requirements of high speed contactless transactions. Additionally a SPI compatible interface will be supported. The MF RC531 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 14443 A& B. 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 (R) (R) 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.

3.2 Pin Description 3.2.1 ANTENNA INTERFACE The contactless antenna interface basically uses four pins: Name TX1, TX2 VMID RX Type O Buffered Analog I Analog Function Antenna Drivers Reference Voltage Antenna Input Signal
To drive the antenna the MF RC531 provides the energy carrier of 13.56 MHz through TX1 and TX2. This signal is modulated by the transmitting data according the register settings. The card responds with load modulation of the RF field. The resulting signal picked up by the antenna is coupled out from the antenna matching circuit and forwarded to the RX-pin. Inside the MF RC531 the receiver senses and demodulates the signal and processes it according to the register settings. Data is passed further on to the parallel interface where it is accessible by the -Controller. The MF RC531 uses a separate power supply for the driver stage. Name TVDD TGND Type Power Power Function Transmitter Supply Voltage Transmitter Supply Ground
3.2.2 ANALOG SUPPLY For best performance the MF RC531 analog part has a separate supply. It powers the oscillator, the analog demodulator and decoder circuitry. Name AVDD AGND Type Power Power Function Analog Positive Supply Voltage Analog Supply Ground
3.2.3 DIGITAL SUPPLY The MF RC531 uses a separate digital supply. Name DVDD DGND Type Power Power Function Digital Positive Supply Voltage Digital Supply Ground
3.2.4 AUXILLARY PIN Internal signals may be selected to drive this pin. It is used for design-in support and test purpose.

3.2.5 RESET PIN The reset pin disables internal current sources and clocks and detaches the MF RC531 virtually from the C bus. If RST is released, the MF RC531 executes the power up sequence. 3.2.6 OSCILLATOR Name XIN XOUT Type I O Function Oscillator Buffer Input Oscillator Buffer Output
The very fast on-chip oscillator buffer operates with a 13.56 MHz crystal connected to XIN and XOUT. If the device shall operate with an external clock it may be applied to pin XIN. 3.2.7 MIFARE (R) INTERFACE

The MIFARE interface may be used to communicate with either the analog or the digital part of the MF RC531 separately in the following ways: * * The analog circuit may be used stand-alone via the MIFARE interface. In that case MFIN will be connected to the externally generated NPAUSE signal. The MFOUT pin provides the KOMP signal. The digital circuit may be used to drive an external analog circuit via the MIFARE interface. In that case the MFOUT pin provides the internally generated NPAUSE signal and MFIN will be connected to the KOMP signal from the outside.

3.3 Applications 3.3.1 CONNECTING DIFFERENT CONTROLLER'S The MF RC531 supports different parallel C interfaces and a SPI compatible interface. An intelligent autodetection logic automatically adapts the parallel interface to the respective bus system. Selection of the device is performed with signal NCS. To connect -Controllers using separated address and data bus pin ALE has to be connected to DVDD. To connect -Controllers using multiplexed address and data bus pin ALE has to be connected to the signal ALE of the -Controller To connect -Controllers using RNW and NDS (instead of NWR and NRD) the -Controller's RNW has to be connected to pin NWR and NDS to pin NRD.

4 MIFARE CLASSIC RELATED ITEMS 4.1 CRYPTO I: Card Authentication For correct authentication of MIFARE (R) Classic products the fast CRYPTO 1 stream cipher is available. The corresponding keys have to be programmed into the secure non-volatile key memory of the MF RC531. Only two commands need to be sent by application software to turn on CRYPTO 1 secured communication. 4.1.1 INITIATING CARD AUTHENTICATION The correct key for the authentication has to be selected from the secure internal non-volatile key memory and loaded into the internal CRYPTO1 register. Next the authentication command is transmitted to the card. After receiving the first message token from the card, the -Controller has to check the The card will respond with the second message token. Then the communication status flags have to be checked by the -Controller. If authentication has been successful further communication with a MIFARE (R) Classic card continues CRYPTO 1 enciphered. communication status flags. If communication so far has been successful the second part of the authentication procedure can be started. 4.1.2 SECOND PART OF CARD AUTHENTICATION Data to be transmitted to the card in this phase are generated automatically by the internal CRYPTO 1 unit inside the MF RC531. To request this action the according command has to be triggered.
