1. Introduction
This document describes the functionality and electrical specifications of the contactless
reader/writer MFRC522.
Remark:
The MFRC522 supports all variants of the MIFARE Mini, MIFARE 1K,
MIFARE 4K, MIFARE Ultralight, MIFARE DESFire EV1 and MIFARE Plus RF
identification protocols. To aid readability throughout this data sheet, the MIFARE Mini,
MIFARE 1K, MIFARE 4K, MIFARE Ultralight, MIFARE DESFire EV1 and MIFARE Plus
products and protocols have the generic name MIFARE.
2. General description
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)
I
2
C-bus interface
3. Features and benefits
Highly integrated analog circuitry to demodulate and decode responses
Buffered output drivers for connecting an antenna with the minimum number of
external components
Supports ISO/IEC 14443 A/MIFARE
Typical operating distance in Read/Write mode up to 50 mm depending on the
antenna size and tuning
