          的詳細介紹
          MFRC5231. Introduction
          This document describes the functionality and electrical specifications of the contactless
          reader/writer MFRC523.
          1.1 Different available versions
          The MFRC523 is available in two versions:
          ? MFRC52302 (HVQFN32), hereafter named as version 2.0
          ? MFRC52301 (HVQFN32), hereafter named as version 1.0
          The differences of the version 1.0 to the version 2.0 are summarized in Section 11.
          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.
          All protocol layers of the ISO/IEC 14443 A and ISO/IEC 14443 B communication
          standards are supported provided:
          ? additional components, such as the oscillator, power supply, coil etc are correctly
          applied
          ? standardized protocols, such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B
          anticollision are correctly implemented
          The MFRC523 supports contactless communication using MIFARE higher baud rates
          (see Section 8.3.4.11 on page 22) at 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 dependent on pin voltage supply)
          ? I 2 C-bus interface
