MFRC522 Contactless reader IC

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.

The MFRC522 supports MF1xxS20, MF1xxS70 and MF1xxS50 products. The MFRC522 supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions.

The following host interfaces are provided:

Serial Peripheral Interface (SPI)
Serial UART (similar to RS232 with voltage levels dependant on pin voltage supply)
I²C-bus interface

Differences between version 1.0 and 2.0

The MFRC522 is available in two versions:

MFRC52201HN1, hereafter referred to version 1.0 and

MFRC52202HN1, hereafter referred to version 2.0

The MFRC522 version 2.0 is fully compatible to version 1.0 and offers in addition the following features and improvements:

Increased stability of the reader IC in rough conditions

An additional timer prescaler

A corrected CRC handling when RX Multiple is set to 1
