Summary 】 【 RC522 chip

  MF RC522 is applied to the 13.56 MHz non-contact card chip, communication of high integration, speaking, reading and writing is based on "three tables" N.X P company launched 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 verify mi. The fare series products.Support mi MFRC522. Fare series 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.

【 RFID module introduction 】

MF522 - AN module USES the PHI. LIPS MFRC522 original chip card read circuit design, easy to use, low cost, applicable to the equipment development, development of reader of users, the need for advanced applications such as radio frequency 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;
