1. Introduction
This document describes the functionality and electrical specifications of the contactless
reader/writer MFRC523.
2. General description
The MFRC523 is a highly integrated reader/writer for contactless communication at
13.56 MHz. The MFRC523 reader supports ISO/IEC 14443 A/MIFARE mode.
The MFRC523’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 MFRC523 supports MIFARE Mini, MIFARE 1K and MIFARE 4K (MIFARE Standard)
products. The MFRC523 supports contactless communication and uses MIFARE higher
transfer speeds up to 848 kBd in both directions.
The MFRC523 supports all layers of the ISO/IEC 14443 B reader/writer communication
protocol provided that, external components such as oscillator, power supply and coil, and
standard protocols such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B anticollision are
correctly implemented.
Note that the use of this NXP Semiconductors device in accordance with
ISO/IEC 14443 B may infringe on third-party patent rights. It is the responsibility of the
user to ensure that appropriate third-party patent licenses exist.
The following host interfaces are provided:
• Serial Peripheral Interface (SPI)
• Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)
• I2C-bus interface

8.3.2.2 SPI write data
To write data to the MFRC523 using SPI requires the byte order shown in Table 7. It is
possible to write up to n data bytes by only sending one address byte.
The first send byte defines both the mode and the address byte.

8.3.2.3 SPI address byte
The address byte must meet the following format.
The MSB of the first byte defines the mode used. To read data from the MFRC523 the
MSB is set to logic 1. To write data to the MFRC523 the MSB must be set to logic 0. Bits 6
to 1 define the address and the LSB is set to logic 0.
