1.Introduction
This document describes the functionality of the contactless reader/writer
YHY522R . It includes the functional and electrical specifications.
2. General description
The YHY522R is a highly integrated reader/writer for contactless
communication at 13.56MHz.The YHY522R reader supports ISO14443A/
MIFARE®mode.
The YHY522R has built-in transceiver antenna to communicate with
ISO/IEC 14443A/ MIFARE®cards without additional circuitry. The module
provides a robust and efficient implementation of a demodulation and
decoding circuitry for signals from ISO/IEC 14443A/ MIFARE®compatible
cards and transponders. 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. The user does not need
input three steps : request, anticollision and selection. The module will do this
function for you automatically. What you need is just sending one command
to the module. Then it will send back what you want. Anything is just so
simple and so easy. Also, if there is any card goes into the rf field, the red led
on the module will light and the IRQ pin will change from “1” to “0” to indicate
the event.
Host interface : Serial RS232

10.3 Slection of the transfer speeds
The default transfer speed is 19.2 kbit/s.
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.

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.
10.4.1 Host to YHY522R Transfer Protocol
Table 5. UART frame send by host
1.
1. Header: This header has 2 bytes that indicates the beginning of a frame. These 2
bytes should be always 0xAA 0xBB.
2. Length: This byte is used to indicate the length of the payload data. This includes
the Length, Command and the Data bytes.
3. Command: This byte is used to instruct the module on what operation to perform.
4. Data: These are parameters for the module to execute the command. For example,
for a Read command, the data will be the block number to be read and the
authenticated key. For a Write command, this will be the block number and
the authenticated key and 16 bytes data to write into the block. For other
command, it maybe empty.
5. CSUM: This is the checksum byte. This byte is used on the host as well as the
module to check the validity of the packet and to trap any data
corruption. This is calculated by XOR all the bytes in the packet except
the Header and the CSUM byte.
CSUM=Length⊕Command⊕Data[0]⊕Data[1]…⊕Data[n-1]
Note: If there is one byte “0xAA” in the packet data from Length to CSUM，please
insert one byte “0x00” after “0xAA”,but the Length need not change.
Code example:
//--------------------------------------------------
if (cSendBuffer[i] == 0xAA)
{
TI = 0;
SBUF = 0;
while (!TI);
}

1. Header: This header has 2 bytes that indicates the beginning of a frame. These 2
bytes should be always 0xAA 0xBB.
2. Length: This byte is used to indicate the length of the payload data. This includes
the Length, Command and the Data bytes
3. Status: This is the status for which the response is being sent back. If ok then the
module return the command which host has sent, if failure it return the
ones-complement code. For example, the command is 0x19, then the
ones-complement code is 0xe6.
4. Data: This contains the result data if an operation was successful. It may be empty.
5. CSUM: This is the checksum byte. This byte is used on the host as well as the
module to check the validity of the packet and to trap any data
corruption. This is calculated by XOR all the bytes in the packet except
the Header and CSUM byte.

12. 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.
The output pins are frozen at a certain value.
12.2 Transmitter Soft Power-down
The Transmitter Soft Power-down mode is entered immediately after send
command 0x11 to the YHY522R . The module will switch off the antenna
power, but the mcu is still working.
13. Reset ___ ___________________ _
The YHY522R is reset when a low level is present on the RST pin for
longer than the minimum pulse length. During Reset, all I/O pins are set to
their initial states, and the program starts execution from the Reset Vector.

Notes: The Power-on Reset will not work unless the supply voltage has been
below VPOT (falling).

14. YHY522R Command Set ___ ____________________
14.1 Commands overview
The commands for the YHY522R include system commands and RFID
commands.
The system commands are use for controling the module settings and save
parameters to the EEPROM.
The RFID commands are use to operating the RFID card, such as read or
write block data.

14.2 Commands and Response
After power on or reset YHY522R , the RED led will flash one time, It means
that YHY522R is ready.
If a Mifare®tag detected by the module, pin IRQ will change from “1” to “0”
and the red led on board will light till the tag moves out of rf field.
The RED led will flash during data stream exchanging between host and
YHY522R .
