RC522 RFID 13.56MHz Read/Write Card Reader

Description

The RFID Module RC522 Kit is a low-cost  MFRC522 based RFID Reader Module that is easy to use and can be used in a wide range of applications. The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz.

Features

• Highly integrated modulation and demodulation circuit;
• A small number of external devices can be used to connect the output driver stage to the antenna;
• Support ISO / IEC 14443 TypeA and MIFARE® communication protocol;
• The communication distance with ISO 14443A / MIFARE® in the reader mode is up to 50mm, depending on the length and tuning of the antenna.
• Supports ISO 14443 212kbit / s and 424kbit / s higher transmission rate communication.
• Support MIFARE® Classic encryption;
• 64-byte send and receive FIFO buffer;
• Flexible interrupt mode;
• Programmable timer.
• It has three power-saving modes: hardware power down, software power down, and transmitter power down. The first two modes are similar to MFRC500 and CL RC400. Its unique “transmitter power down” can turn off the internal antenna driver, that is, turn off the RF field
• Built-in temperature sensor to automatically stop RF transmission when the chip temperature is too high
• Adopt multiple independent sets of power supply to avoid mutual interference between modules and improve the stability of work
• With CRC and parity check functions, the 16-bit long CRC calculation polynomial of the CRC coprocessor is fixed as x16 + x12 + x5 + 1, which conforms to ISO / 1EC14443 and CCTITT protocols
• Internal oscillator, connected to 27.12MHz crystal
• Operating Current :13-26mA/DC 3.3V
• Idle Current :10-13mA/DC 3.3V
• Sleep Current:: less than 80uA
