TK5552 Read/Write Transponder
TMEB8704 Application Note
Figure 5-10. TK5552 Read Tab
When the transponder TK5552 is selected, the Read tab of the TK5552 user interface is shown.
This page enables setting the following parameters in the Configuration Setup (on the left side):
Note:
To change the Configuration Setup, click the Configure Transponder button to program the con-
figuration block of the transponder. (The transponder should be placed close to the application
board antenna.)
Click Read Timing on the right side to set the timing parameters for decoding. Under normal
operating conditions, the default values can be used.
To read out the transponder, use the Read button. The decoding principle, in simple terms, is to
send the chosen Configuration and Read Timing to the microcontroller on the RFID application
• Bit rate: Rf/16 and Rf/32
• Coding: Manchester and PSK
• ID-code length: Block 0, Block 1, Block 1 to 2, Block 1 to 3,...,Block 1 to 31
• Signature: Header
• Lock Block 0:
• Start-up delay: No (only POR) or POR and additional 8192 clocks of the RF-field
• Modulation defeat:
Setting this bit locks the configuration block of the transponder. This means bit rate, coding,
etc. are fixed and cannot be changed anymore. Please use this feature with care
When Mod. off is activated, no data will be transmitted. It will appear as if no transponder is in
the RF field
The U2270B is not able to read all bit rates and coding types displayed. If invalid settings have
been selected, a warning message will be displayed. For details, please refer to the e5552
datasheet in the TK5552 appendix.
