  • Pin Function:
Pin Number Pin Name Description
1 VCC Used to Power the module, typically 3.3V is used
2 RST Reset pin – used to reset or power down the module
3 Ground Connected to Ground of system
4 IRQ Interrupt pin – used to wake up the module when a device comes into range
5 MISO/SCL/Tx MISO pin when used for SPI communication, acts as SCL for I2c and Tx for UART.
6 MOSI Master out slave in pin for SPI communication
7 SCK Serial Clock pin – used to provide clock source
8 MOSI Acts as Serial input (SS) for SPI communication, SDA for IIC and Rx during UART
The RC522 may be a 13.56MHz RFID module that’s supported the MFRC522 controller from NXP semiconductors. The module can support I2C, SPI and UART and normally is shipped with a RFID card and key fob. It is commonly used in attendance systems and other person/object identification applications.This is RFID Reader/Writer RC522 SPI S50 CARD AND KEYCHAIN which works on non-contact 13.56mhz communication, is designed by NXP as low power consumption, low cost and compact size read and write chip, is that the most suitable option within the development of smart meters and portable hand-held devices.
It uses the advanced modulation system, fully integrated at 13.56MHz with all kinds of positive non-contact communication protocols. Support 14443A compatible answer signal. DSP deal with ISO14443A frames and error correction.
This module can fit directly in handheld devices for mass production. The module uses the 3.3V power supply and can communicate directly with any CPU board by connecting through the SPI protocol, which ensures reliable work, good reading distance.MF RC522 is applied to 13.56MHz contactless communication highly integrated chip card reader, is NXP for the “Three Tables” application launch of a low-voltage, low-cost, small size and non-contact card reader chip, smart instrumentation and portable handheld devices developed more sensible choice . MF RC522 using advanced modulation and demodulation concept completely integrated altogether sorts of 13.56MHz passive contactless communication methods and protocols. 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 scale back connection, reduce PCB board size and price.
