INTRODUCTION TO RC522 CHIP
MF RC522 is a high integrated read-write card chip used in 13.56MHz
contactlesscommunication. It is a low-voltage, low-cost, small size
contactless read-write card chipwhich is a good choice for the
research and development of intelligent instruments andportable
handheld devices. MF rc522 fully integrates all kinds of passive
non-contactcommunication modes and protocols at 13.56MHz by using
advanced modulation anddemodulation concepts. Support 14443a
compatible transponder signal. The digital partprocesses iso 14443a
frame and error detection. ln addition, it also supports fast cryp
to 1 encryption algorithm to verify Mifare series products. Mfrc522
supports higher speedcontactless communication of Mifare series,
with bidirectional data transmission rate upto 424kbit / s. As a
new member of 13.56MHz high integration read-write card family. MF
RC522 has many similarities with MF RC500 and MF rc530, but also
has manycharacteristics and differences. lt uses SPI mode to
communicate with the host computer,which is helpful to reduce the
wiring, reduce the volume of PCB board and reduce thecost.
INTRODUCTION TO RFID MODULE
MF522-AN module adopts MFRC522 original chip to design card reading
circuit,which is convenient to use and low-cost.It is suitable for
advanced application users suchas equipment development, card
reader development, and users who need to design /produce RF card
terminal. The module can be directly loaded into various reader
molds. The voltage of the module is 3.3V, and it can directly
communicate with any CPUmotherboard of the user through a few
simple lines of SPI interface, which can ensure thestable and
reliable operation of the module and the long distance of card
reading;
