Hi,
sorry but my English is very bad

I have an Enhanced Willem Programmer.
I want to program a chip AN28F512-120 (PLCC32).
I can read, but I can't erase ("time out")the chip, and when I want to program a new soft on the chip, I have error, for exemple: "error at 0*0000D3 Chip=0*00 buffer=0*01"...

Can you help me please...
thank
Ludo.

If all settings are correct, then you should be able to get the ID correctly.
The device 28F512 should be selected.
You have to erase the chip before write.

If you can not erase the chip, please check if it is a bad chip.

Hello,

my problem is solved!
I found this message : http://www.mcumall.com/forum/topic.asp?TOPIC_ID=93
and the LTP port BIOS setting wasn't EPP mode... now it's OK, I can read, erase and flash!
and now ID is 0*89 (intel), 0*B8.

Thank you for your assistance
