  • Page 4: Introduction

    The digital part handles the complete ISO/IEC 14443A framing and error detection(Parity & CRC). In the master mode, YHY522R will seek the card or data itself and output to host automatically. In the slave mode, the module just needs only one command to finish one action, such as read or write data from card’s block.

To change the transfer speed, the host controller has to write a value for the new transfer speed by the CONFIG command, after reset the module, the new speed will active.

  • Page 9: Host To Yhy522R Transfer Protocol

    EHUOYAN YHY522R RFID module The original setting for the host and YHY522R communicates at 19200bps, N, 8, 1. In the slave mode, the host first sends the command and the module executes the operation and replies with a response to the command. The host can analyze the reply to check if the operation was successful or if any error occurred during the operation.

  • Page 10: Power Reduction Mode

    12.1 Hard Power-down A Hard Power-down is enabled with sending command 0x03 to the YHY522R . This turns off all internal current sinks as well as the oscillator. All digital input buffers are separated from the input pads and clamped internally.
