MF RC522 is applied to 13.56MHz contactless communication high integrated card reader chip is NXP company for the "three table" Application of the launch of a low voltage, low cost, small volume of the contactless card chip reader, smart instrumentation and portable handheld device developed by MF RC522 with a better choice. The modulation and demodulation of the concept of advanced, fully integrated 13.56MHz in all types of passive non-contact communication modes and protocols. Support 14443A compatible transponder signal. The digital part of ISO14443A frames and error detection. In addition, CRYPTO1 also supports fast encryption algorithm, MIFARE language verification products.MFRC522 MIFARE series high-speed non support contact communication, bidirectional data transfer rate up to 424kbit/s. as high integrated 13.56MHz card reader chip series of new members of the family, MF RC522 and MF RC500 and MF RC530 have many similar. At the same time, it also has many characteristics and differences. It uses SPI mode to communicate with the host computer, which is beneficial to reduce the connection, reduce the volume of the PCB board and reduce the cost
[brief introduction of RFID module]
The MF522-AN module adopts the design of original Philips chip MFRC522 card circuit, convenient use, low cost, suitable for equipment development, reader development and other senior application users need RF card terminal design / production users. This module can be loaded directly into a variety of card reader module using the mold. The voltage is 3.3V, through a few line a simple SPI interface can be directly connected with the user of any CPU motherboard communication module can ensure stable and reliable work, the card reading distance;
Ambient storage temperature: -40 to 85 degrees Celsius
