RC522 chip introduction

MF RC522 is applied to the 13.56 MHz card chip contactless communication high integration, speaking, reading and writing, is a low voltage, low cost, small volume of card chip, non-contact, speaking, reading and writing is intelligent instrument and a portable handheld device research and development of a good choice. MF RC522 took advantage of the advanced concept of modulation and demodulation, fully integrates all types of passive under 13.56 MHz contactless communication mode and protocol. Support 14443 a compatible transponder signal. Digital part processing ISO14443A frame and error detection. In addition, also supports fast CRYPTO1 encryption algorithm, language validation non-contactseries products. MFRC522 support non-contac tseries more high-speed contactless communication, two-way data transfer rate is as high as 424 kbit/s. As 13.56 MHz card series chips, high integration, speaking, reading and writing the new members of the family, MF RC522 with MF RC500 and MF RC530 has many similarities, it also has many characteristics and differences. It with the communication between the host USES the SPI mode, is beneficial to reduce the attachment, PCB volume, reduce the cost.

Introduction of RFID module

 

MFRC522 original chip card read circuit design, easy to use, low cost, applicable to the equipment development, development of card reader advanced application of users, the need for rf card terminal design/production of users. This module can be directly into the various card reader mold. Module USES the voltage of 3.3 V, through SPI interface simple lines can be directly connected to the user any CPU mainboard communication, can ensure that the module is stable and reliable work, reading card distance;
