The RC522 is a 13.56MHz RFID module that’s primarily based on the MFRC522 controller from NXP semiconductors. The module can assist I2C, SPI and UART and usually is shipped with a RFID card and key fob. It’s generally utilized in attendance programs and different particular person/object identification purposes.
Pin Operate:
| Pin Quantity | Pin Title | Description |
| 1 | VCC | Used to Energy the module, sometimes 3.3V is used |
| 2 | RST | Reset pin – used to reset or energy down the module |
| 3 | Floor | Linked to Floor of system |
| 4 | IRQ | Interrupt pin – used to get up the module when a tool comes into vary |
| 5 | MISO/SCL/Tx | MISO pin when used for SPI communication, acts as SCL for I2c and Tx for UART. |
| 6 | MOSI | Grasp out slave in pin for SPI communication |
| 7 | SCK | Serial Clock pin – used to offer clock supply |
| 8 | MOSI | Acts as Serial enter (SS) for SPI communication, SDA for IIC and Rx throughout UART |
The RC522 could also be a 13.56MHz RFID module that is supported the MFRC522 controller from NXP semiconductors. The module can assist I2C, SPI and UART and usually is shipped with a RFID card and key fob. It’s generally utilized in attendance programs and different particular person/object identification purposes.That is RFID Reader/Author RC522 SPI S50 CARD AND KEYCHAIN which works on non-contact 13.56mhz communication, is designed by NXP as low energy consumption, low value and compact measurement learn and write chip, is that the most suitable choice throughout the growth of sensible meters and moveable hand-held gadgets.
It makes use of the superior modulation system, totally built-in at 13.56MHz with all types of optimistic non-contact communication protocols. Assist 14443A appropriate reply sign. DSP cope with ISO14443A frames and error correction.
This module can match immediately in handheld gadgets for mass manufacturing. The module makes use of the three.3V energy provide and might talk immediately with any CPU board by connecting via the SPI protocol, which ensures dependable work, good studying distance.MF RC522 is utilized to 13.56MHz contactless communication extremely built-in chip card reader, is NXP for the “Three Tables” utility launch of a low-voltage, low-cost, small measurement and non-contact card reader chip, sensible instrumentation and moveable handheld gadgets developed extra good selection . MF RC522 utilizing superior modulation and demodulation idea utterly built-in altogether types of 13.56MHz passive contactless communication strategies and protocols. Assist 14443A appropriate transponder indicators. The digital half handles ISO14443A framing and error detection. As well as, assist quick CRYPTO1 encryption algorithms, terminology validation MIFARE merchandise. MFRC522 helps MIFARE Collection greater velocity non-contact communication, two-way information switch charges as much as 424kbit / s. As a extremely built-in 13.56MHz card reader new household of chips, MF RC522 MF RC500 and MF RC530 and there are a lot of similarities, but additionally have many options and variations. It’s between the host communication utilizing SPI mode, helps to cut back connection, cut back PCB board measurement and value.
