MF RC522 is applied to the highly integrated read and write 13.56MHz contactless communication card chipNXP launched by the company for the "table" application of a low-voltagelow-costsmall size of the non-contact card chip to read and writesmart meters and portable handheld devices developed better choice. The MF RC522 use of advanced modulation and demodulation concept completely integrated in all types of 13.56MHz passive contactless communication methods and protocols. 14443A compatible transponder signals. The digital part of to handle the ISO14443A frames and error detection. In additionsupport rapid CRYPTO1 encryption algorithmterminology validation MIFARE products. MFRC522 support MIFARE series of high-speed non-contact communicationtwo-way data transmission rate up to 424kbit/s. As new members of the 13.56MHz reader card series of highly integrated chip familyMF RC522 MF RC500 MF RC530 There are a lot of similaritiesbut also have many of the characteristics and differences. Communication between it and the host SPI mode helps to reduce the connection narrow PCB board volumereduce costs.
The MF522-AN module the the original Philips MFRC522 chip design circuit card readereasy to uselow costand applies to the user equipment developmentthe reader and the development of advanced applicationsthe need for the user RF card terminal design/production. This module can be directly loaded into the various reader molds. Utilizes a voltage of 3.3Vthrough the SPI interface simple few lines directly with any user CPU motherboard connected communication can ensure that the module is stable and reliable workdistance card reader;
