Hello I have top 853 eprom programmer. I'm using topwin ver 6.08 with windows vista. When I try burn the SST27SF512 I did take an error. But I can read and erase with free of problem. Can anyone help me for this subject ?
there apps are stupid locate this branch in the device853.lst file right click it and choose edit within the normaly C:\Top\Topwin6 folder if you dont set this way the vcc level strange things happen the chinese dont make fireworks for nothing added ,vcc=5000 for 5v and dly=3 for 1ms spool delay
disconnect all other usb stuff reboot then plug in the programmer
then reboot windows is crap at having to adjust to badly written jongo drivers like this programmer's reuse
you may find your programmer has some dry joints or bad solders it can work for some and not many others and some familys ground pins are used for other signals within other chips families
i suspect you have a couple of dry solder joints at the vpp pin many people complain about this and its worthwhile opening it up and checking over it
other than this there is no reason why it wont work with these settings have you tried other ic's like this before
i do note that your device requires a slightly different programming technique to the others in the same family you could try with an older version of there software also
