1 / 96 page  1. Introduction This document describes the functionality and electrical specifications of the contactless reader/writer MFRC522. 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) • I2C-bus interface 3. Features I Highly integrated analog circuitry to demodulate and decode responses I Buffered output drivers for connecting an antenna with the minimum number of external components I Supports ISO/IEC 14443 A/MIFARE I Typical operating distance in Read/Write mode up to 50 mm depending on the antenna size and tuning I Supports MF1xxS20, MF1xxS70 and MF1xxS50 encryption in Read/Write mode I Supports ISO/IEC 14443 A higher transfer speed communication up to 848 kBd I Supports MFIN/MFOUT I Additional internal power supply to the smart card IC connected via MFIN/MFOUT I Supported host interfaces MFRC522 Contactless reader IC Rev. 3.3 — 26 October 2009 112133 Product data sheet PUBLIC |
