MF RC522 is a high integrated read-write card chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small size and contactless read-write card chip, which is a good choice for smart instrumentation and portable handheld devices developed. MF RC522 fully integrates all kinds of passive non-contact communication models and protocols at 13.56MHz by using advanced modulation and demodulation concepts. Support 14443A compatible transponder signals. The digital part handles ISO14443A framing and error detection. In addition, support fast CRYPTO1 encryption algorithms, terminology validation MIFARE products. MFRC522 supports MIFARE Series higher speed non-contact communication, two-way data transfer rates up to 424kbit / s. As a highly integrated 13.56MHz card reader new family of chips, MF RC522 MF RC500 and MF RC530 and there are many similarities, but also have many features and differences. It is between the host communication using SPI mode, helps to reduce connection, reduce PCB board size and cost.
MF522-AN module adopts Philips MFRC522 original chip to design card reading circuit, which is easy to use, low cost, suitable for equipment development, development of advanced applications such reader users, the need for RF card terminal design / production of the user. This module can be loaded directly into a variety of readers molds. Module uses voltage of 3.3V, through the SPI interface simple few lines can be directly connected to the user any CPU board communication module can guarantee stable and reliable work, reader distance.
