Product Overview

The MFRC522 is most highly integrated reader/writer IC, which works seamlessly as contactless communicator at the speed of 13.56 MHz. The IC supports a standard of identification cards and those are, ISO/IEC 14443 A/MIFARE and NTAG. From these compatible cards and transponders, the receiver module provides a robust and efficient implementation for demodulating and decoding signals. The digital module also successfully manages the complete ISO/IEC 14443, which is a framing and error detection functionality. The MFRC522 supports MF1xxS20, MF1xxS70 and MF1xxS50 products and contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions.
