DVK90109
General Description
The development kit DVK90109 has been developed by Melexis to create specific applications using 125 kHz
protocols and to evaluate the advantages of the MLX90109 transceiver IC.
The DVK90109 results of the combination of the development board DVKRFID and the evaluation board
EVB90109. The EVB90109 is plugged on the DVKRFID through a 10 pins connector (including Coil, VCC and
Ground) and controlled by the microcontroller ATMEGA128.
A set of commands has been elaborated by Melexis to define the communication between the Computer and the
evaluation board EVB90109.

RFID
This part specifies a dedicated set of commands useful for the operation with the MLX90109 RFID transceiver
IC.
This instruction set is defined for the development kit DVK90109.
The microcontroller ensures the following functions:
o Control and configure the MLX90109 transceiver
o Read the data information from the MLX90109 transceiver (on-chip decoding)
o Communicate with a PC through the serial connection RS232.
4.1 Protocol assignment
The different commands are based on a Mnemonic assignment defined by three ASCII characters forming the
Operation Code, followed by a specific number of ASCII or Hexadecimal parameters, depending on the type of
the command.
OP CODE : 3 ASCII characters
PARAMETERS : ASCII characters or
Hexadecimal characters
The syntax of a command is typically: OpCode<Parameter1>,<Parameter2>,<Parameter3>,…
Each parameter should be separated by a comma.

WRite Hitag1 WRH,<command>,<address>,<data>↵ Perform a write operation for Hiatg1 tag with the data defined in the <data>
parameter
Note: Be careful that a value is necessary in all fields defined by the instruction. The default value defined in the
following instruction set is only the value set by the program during the initialization phase. This means that if the
CFG instruction is not sent, the <Encoding> and <Baudrate> fields will take default values being respectively
biphase and 4kbit/s.
4.3 Error Instruction
No Name Meaning Message
0 Instruction error If the Opcode syntax is not correct or not defined.
err0↵
1 Definition error If the definition syntax is not correct.
err1↵
2 No tag detected If no transponder has been detected.
err2↵
3 Header not found If the header cannot be found in the read code.
err3
5 Read operation failed If the calculated CRC or parity check doesn’t correspond to the read value. err5↵
6 Others error err6↵
8 Measure Frequency Antenna If a problem occurs during antenna frequency measurement (value too high, no
signal …)
err8↵
4.4 Instructions set
4.4.1 Version (VER)

This command can be used to control the serial connection RS232.
Syntax VER↵
Return Melexis RFID <Development kit> V<Version>
Example VER↵
Reply: Melexis RFID DVK90109 V2.0
4.4.2 Set Field (STF)
Set the magnetic field ON or OFF.
Syntax STF<on/off>↵
<on/off> = Characters defining the current state of the field (<on> to put the field ON and <off> to put the field OFF).
Default value: <on>.
Return Ok

4.4.3 Configuration of the MLX90109 (CFG)
Set the configuration of the transceiver to decode data information from a transponder (encoding mode and data
rate).
Syntax CFG<Encoding>,<Datarate>↵
<Encoding> = ASCII letter specifying the encoding method used by the Transponder (<M> for Manchester and <B> for
Biphase). Default value: <B>.
<Datarate> = ASCII number specifying the data rate used by the transponder (<2> for 2kbits/s, <4> for 4kbits/s). Default
value: <4>.
Return Ok
Example CFGB,4↵
Reply: Ok
4.4.4 HEA : HEAder
Specify the header of the data sent by the transponder.
The program will search for the header in the data read from the transponder and display the data with the
header first.
The header is a number of bits that cannot be reproduced in the rest of the ID. For example in the standard norm
ISO11784, the first 11 bits of the ID code will be used as the header and fixed to “0000 0000 001”.
Syntax HEA<Header>,<Nbr significant bit>↵
<Header> = Hexadecimal number defining the header.
<Nbr unused bit> = Hexadecimal number defining the number of Header bits to be removed (mustn’t be higher than 7).
Return Ok <Header in binary>
Example HEA0020,5↵
Reply: Ok 00000000001
HEA002010,7↵
Reply: Ok 00000000001000000
Example: The header is calculated with two parameters. <Header> defining the header in hexadecimal (an entire
number of byte is necessary) and <Nbr Of Unused bit> a decimal number defining the number of bits which are
to be removed from the given Header to form the new Header. Thus, it is possible to define a length of header
different of a power of 2.
HEA0020,5 = 0000 0000 0010 0000 = 0000 0000 001
4.4.5 REA : REAd
Read, decode and return data from a transponder.
If a problem occurs during operation (no header found, no transponder), an error message will be displayed as
referenced in the table 1.3 Error Instruction.
Syntax REA<Opmode>,<Nbr of bit>↵
<Opmode> = Number defining the programmed decoding method used.
o <1> Searches for the header, decodes ISO11784 mode, controls CRC value and displays the decoded data.

o <2> Searches for the header, decodes Melexis 88bits mode, controls CRC value and displays decoded data.
o <3> Searches for the header and displays the data read.
o <4> Only displays the data read (no decoding, no search for the header).
<Nbr of bit> = ASCII number specifying the number of bit read. <064>, <128>, <144> and <256> are implemented.
Return <data>
err2 (no tag detected)
err3 (no header found)
err5 (read failed)
Example REA1,128↵
Read 128bits, searches for the header and decodes the ID read according to the standard norm ISO11784. Checks the
CRC and returns corresponding message (data read or error).
REA2,128↵
Read 128bits, searches for the header and decodes the ID read according to the Melexis 88 bits encoding method.
Checks the CRC and returns corresponding message (data read or error).
REA3,064↵
Read 64bits, searches for the header and returns corresponding message (data read or error).
REA4,256↵
Reads and displays 256bits.
Note: The ISO11784/85 standard norm and the Melexis 88bits encoding method will be only performed on 128
bits read. So in these two mode (opmode <1> and <2>) the field <Nbr of bit> will be ignored and 128bits will be
always read.
Note: REA command will not set the field of the EVB90109. Before performing a read operation, the field must
be ON by using the STFon command.
4.4.6 WRI : Write Q5 tag
Write data in the Q5 tag memory.
This function will use the 100% modulation (please refer to the application note “100% modulation (On-Off
Keying)”) to write data according to Q5 tag communication protocol.
An “Ok” will confirm the success of the operation.
Syntax WRI,<data>,<address>↵
<data> = 4 bytes data (hexadecimal value) <MSB…LSB>.
<address> = 1 bytes address of the Q5 memory (hexadecimal value).
Return Ok
Err2↵ (no tag detected)
Example WRI,00AA00BB,07↵
Write data 0x00, 0xAA, 0x00 and 0xBB into the block 7 of the Q5 memory
Ok>
Note: WRI command will not set the field of the EVB90109. Before performing a read operation, the field must be
ON by using the STFon command.

Return UID: Unique tag identifier
Configuration page: configuration of the tag (encoding, data rate, security features…)
Err2↵ (no tag detected)
Example SEL↵
UID = 7972C535 / Configuration page = FF370000>
Note: SEL command will not set the field of the EVB90109. Before performing a read operation, the field must be
ON by using the STFon command.
4.4.8 RDH : Read Hitag1 memory
Read an area of the Hitag1 memory.
This function will use the 100% modulation (please refer to the application note “100% modulation (On-Off
Keying)”) to send the selected command and will decode the data sent by the tag according to the Hitag1
communication protocol.
The command RDH will return the data requested in case of success of the operation.
