MIFARE RC522 RFID RF Module Features

1).MF RC522 is a member of the high-integration read-write card series chips used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-sized non-contact read-write card chip launched by NXP Company for the "three-meter" application. It is a better choice for the research and development of smart meters and portable handheld devices.

2). MF RC522 utilizes advanced modulation and demodulation concepts, and fully integrates all types of passive contactless communication methods and protocols under 13.56MHz. Multilayer applications supporting ISO14443A. Its internal transmitter part can drive the communication between reader antenna and ISO 14443A/MIFARE card and transponder without other circuits. The receiver section provides a robust and efficient demodulation and decoding circuit for processing ISO14443A compliant transponder signals. The digital part handles ISO14443A framing and error detection (parity & CRC). Additionally, it supports the fast CRYPTO1 encryption algorithm for authenticating MIFARE series products. MFRC522 supports MIFARE? higher-speed contactless communication, bidirectional data transfer rate up to 424kbit/s.

3). As a new member of the 13.56MHz high-integration card reader series chip family, MF RC522 has many similarities with MF RC500 and MF RC530, and also has many features and differences. The communication between it and the host adopts serial communication with fewer connections, and one of the modes of SPI, I2C or serial UART (similar to RS232) can be selected according to different user requirements, which is beneficial to reduce the connection and reduce the size of the PCB board. ,cut costs.
