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 www.DataSheet4U.com NXP Semiconductors MFRC523 Contactless reader IC 3.
