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;
