Rc522 chip (introduction)

Mf rc522 for 13.56 mhz non-contact communication highly integrated chip card reader,Low pressure for three-meter applications introduced by en zhipu,Low cost,Small size and non-contact card reader chips,Intelligent instrument and portable handheld device development better choice.Mf rc 522 uses advanced modulation and demodulation concepts and is fully integrated into all types of 13.56 mhz passive non-contact communication methods and protocols.Support 1443a compatible transponder signal.The digital part deals with iso 14443 a frame forming and error detection.In addition, fast crypto 1 encryption algorithm is supported, and the term verifies mifare products.Mfrc 522 supports the mifare series of higher-speed non-contact communication, with two-way data transmission rates as high as 424kbit/s.As a highly integrated new series of 13.56 mhz card reader chips, mf rc522 has many similarities with mf rc500 and mf rc530, but also many functions and differences.It communicates between hosts using spi mode, helping to reduce connection, size and cost of pcb board.

(introduction) rfid module

The mf522-an module uses philips mfrc 522 original reader circuit chip design, easy to use, low cost, suitable for equipment development.The module can be loaded directly into various reader molds.Using 3.3v voltage, the module can connect directly to the user with any cpu board communication module through simple lines of spi interface, which can ensure stable and reliable work and long distance of the card reader
