Introduction

AI Translation

The MFRC523 is a highly integrated 13.56 MHz contactless communication reader/writer supporting ISO/IEC 14443 A/MIFARE modes. Its internal transmitter can directly drive an antenna, enabling communication with ISO/IEC 14443 A/MIFARE cards and transponders without additional circuitry. The receiver module efficiently demodulates and decodes signals from these cards and transponders. The digital module handles ISO/IEC 14443 A framing, error detection (parity and CRC), and supports all protocol layers of the ISO/IEC 14443 A and B standards. The MFRC523 supports MIFARE higher baud rates up to 848 kBd in both directions, and provides SPI, serial UART, and I²C bus host interfaces.
