ACT PRO MIFARE DESFIRE EV1 - REV 1.0 Manuel d'utilisateur télécharger pdf

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

C-bus interface

2.1 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:

MFRC522

Standard 3V MIFARE reader solution
