    Problem with QFP32 Socket and tl866 burner to burn Atmega8A(SMD)

    Hi, I use TL866 burner to burn Atmega8A-PU. Now I want to burn Atmega8A-AU (SMD). For that I bought a QFP32 Socket (Adapter) but I dont know how to place IC on socket and how to place socket on burner (TL866). I shared socket on burner picture with attachment.

    Hi,

    You'd better thougt about this before you bought it.

    ****
    You need to ensure that the wiring is in same order as with the AtMega8 DIP case.
    Maybe you need an additional adapter for this, because you can't be sure that every random QFP32 socket is identical.

    Re: Problem with QFP32 Socket and tl866 burner to burn Atmega8A(SMD)

    Hi,

    Do the pins at the bottom side of the QFP adapter fit into the ZIF socket of the programmer? Usually pin1 to pin1.
    (From the pictures it doesn't seem so).

    Hi Klaus, Yes it fit into the ZIF socket of the pragrammer every pin to pin.

    This is my product link.

    Hi,

    and what exactly is the problem then?

    IC in adapter socket: Pin1 on pin1
    Adapter in programmer: pin1 on pin1.

    Re: Problem with QFP32 Socket and tl866 burner to burn Atmega8A(SMD)

    A compatible Atmega8 QFP32 to DIP28 adapter would be expected to have 28 pins.

    The shown adapter has 32 pins, I guess it has a 1:1 pin wiring (you may have already checked). In this case, the adapter can be only used with a specific programmer if the programmer is prepared for performing the required pin mapping. You should check the documentation.

    I found that newer TL866 II supports ATmega QFP32 programming but TL866 doesn't. It would require a special wired adapter according to DIP28 pin mapping. See the information for TL866 II below.

    Hi FvM, Thanks for reply. I am clear from your post. I understand why QFP32/DIP32 socket not working with TL866 burner. I need QFP32/DIP28 socket to work properly with TL866 burner.

    Best Regards.
