MFRC530
ISO/IEC 14443 A Reader IC
Two MFRC530 devices configured as described in
Table 32
can be connected to each
other using pins MFOUT and MFIN.
Remark:
The active antenna concept can only be used at a baud rate of 106 kBd.
9.11.2.2
Driving both RF parts
It is possible to connect both passive and active antennas to a single IC. The passive
antenna pins TX1, TX2 and RX are connected using the appropriate filter and matching
circuit. At the same time an active antenna is connected to pins MFOUT and MFIN. In this
configuration, two RF parts can be driven, one after another, by one microprocessor.
9.12 MIFARE higher baud rates
The MIFARE system is specified with a fixed baud rate of 106 kBd for communication on
the RF interface. The current version of ISO/IEC 14443 A also defines 106 kBd for the
initial phase of a communication between Proximity Integrated Circuit Cards (PICC) and
Proximity Coupling Devices (PCD).
To cover requirements of large data transmissions and to speed up terminal to card
communication, the MFRC530 supports communication at higher MIFARE baud rates in
combination with a microcontroller IC such as the MIFARE ProX.

The MIFARE higher baud rates concept is described in the application note:
MIFARE
Implementation of Higher Baud rates
Ref. 5
. This application covers the integration of the
MIFARE higher baud rates communication concept in current applications.
9.13 MIFARE authentication and Crypto1
The security algorithm used in the MIFARE products is called Crypto1. It is based on a
proprietary stream cipher with a 48-bit key length. To access data on MIFARE cards,
knowledge of the key format is needed. The correct key must be available in the
MFRC530 to enable successful card authentication and access to the card’s data stored
in the EEPROM.
After a card is selected as defined in ISO/IEC 14443 A standard, the user can continue
with the MIFARE protocol. It is mandatory that the card authentication is performed.
Crypto1 authentication is a 3-pass authentication which is automatically performed when
the Authent1 and Authent2 commands are executed (see
Section 11.6.3 on page 87
and
Section 11.6.4 on page 87
).
During the card authentication procedure, the security algorithm is initialized. After a
successful authentication, communication with the MIFARE card is encrypted.
