2 BLOCK DIAGRAM
The block diagram shows the main internal parts
of the MF RC500.
The status and control part allows configuration of
the device to adapt to environmental influences
and to adjust to operate with best performance.
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.
®
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.
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.

I Analog
Antenna Input Signal
To drive the antenna the MF RC500 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 RC500 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 µ-Controller.
The MF RC500 uses a separate power supply for the driver stage.

The MIFARE interface may be used to communicate with either the analog or the digital part of the MF
RC500 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 µCONTROLLER'S
The MF RC500 supports different parallel µC interfaces. An intelligent auto-detection logic automatically
adapts the parallel interface to the respective bus system. Selection of the device is performed with signal
NCS.
To connect µ-Controllers using separated address and data bus pin ALE has to be connected to DVDD.
To connect µ-Controllers using multiplexed address and data bus pin ALE has to be connected to the signal
ALE of the µ-Controller
To connect µ-Controllers using RNW and NDS (instead of NWR and NRD) the µ-Controller’s RNW has to be
connected to pin NWR and NDS to pin NRD.

communication status flags. If communication so
far has been successful the second part of the
authentication procedure can be started.
4.1 CRYPTO I: Card Authentication
For correct authentication of MIFARE  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 RC500.
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 RC500. To request
this action the according command has to be
triggered.
Only two commands need to be sent by
application software to turn on CRYPTO 1
secured communication.
4.1.1 INITIATING CARD AUTHENTICATION
The card will respond with the second message
token. Then the communication status flags have
to be checked by the µ-Controller. If
authentication has been successful further
communication with a MIFARE  Classic card
continues CRYPTO 1 enciphered.
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 µ-Controller has to check the
