RFID - RC522 Kit

MF RC522 is used in highly integrated 13.56MHz contactless communication card chip to read and write, of NXP for “three” and the application launched a low voltage, low cost, small size, non-contact card chip to read and write, intelligent instruments and portable handheld devices developed better.

The MF RC522 use of advanced modulation and demodulation concept completely integrated in the 13.56MHz all kinds of passive contactless communication methods and protocols. 14443A compatible transponder signal. The digital part handles the the ISO14443A frames and error detection. In addition, support Quick CRYPTO1 encryption algorithm, the term verification MIFARE series. MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transfer rates up to 424kbit / s.

As 13.56MHz highly integrated card reader series chip new family, the MF RC522 MF RC500 MF RC530 there are many similarities, but also have many of the characteristics and differences. Communication between it and the host SPI mode, helps to reduce the connection, reduce PCB board volume and reduce costs.

The pinout of the chip is as follows:

1. SDA: Serial Data for I2C (marked with a square solder pad)
2. SCK: Serial Clock for I2C
3. MOSI: Master Out Slave In - for SPI
4. MISO: Master In Slave Out - for SPI
5. IRQ: Interrupt - this pin has multiple functions and should be connected to an interrupt pin on your microcontroller
6. GND: Ground - connect this to ground or 0V
7. RST: Reset - when held low the chip is turned off. Chip resets and powers up on a rising edge
8. 3.3V: Module power supply - connect 2.7V to 3.3V to this pin
