MFRC522 datasheet



The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. The MFRC522 reader supports ISO/IEC 14443 A/MIFARE mode.

The MFRC522’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional active circuitry. The receiver module provides a robust and efficient implementation for demodulating and decoding signals from ISO/IEC 14443 A/MIFARE compatible cards and transponders. The digital module manages the complete ISO/IEC 14443 A framing and error detection (parity and CRC) functionality.


1. Highly integrated analog circuitry to demodulate and decode responses

2. Buffered output drivers for connecting an antenna with the minimum number of
external components

3. FIFO buffer handles 64 byte send and receive

4. Flexible interrupt modes

5. Hard reset with low power function

6. Power-down by software mode

7. Programmable timer
