Thanks for the schematic, it is very helpful So I think I have to select 27C160 in the software, but I have to set the DIP switch according to 27C801 The wiring can also be improved as well, by applying a jumper to Pin2 and Pin3 of J4, pin 1 of zif will be A19 (instead of VPP), and I need only one w...

It seems VPP line of 27C160 isn't compatible with 27C322. But VPP line of 27C801 is compatible with 27C322 : http://8pic.ir/images/pek95xuhjfd9a7rbezn6_thumb.png So I think wiring is not enough and I have to adjust the DIP switch too : 27C322 : http://8pic.ir/images/b7kxkdwbto7bg50sk1az_thumb.png 27...

First of all thanks for the answer But it seems you didn't get the point, I am using this chip in 8bit mode and it works fine. If you don't use D8 ~ D15 data lines, the chip will be 8bit. And yeah I know by doing so the half of the chip goes waste, but it is ok with me! I am trying to find a better ...

M27C322 has A0 ~ A20 and D0 ~ D15 so it is 2MB x 16bit But I want to use it in 8bit mode (2MB x 8bit), so I just ignore D8 ~ D15 pins completely For now I am programming it with a custom adapter : http://8pic.ir/images/30yxlutp8waeidm46g51_thumb.jpg And I select 27C080 in the software 27C080 has A0 ...

Keep chip and settings . Go to SW option : Get ID. What is response ? Screenshot ? This is one of them but the numbers are different for each chip : http://www.8pic.ir/images/xoy7hg00v6qsjwu07nt6.png Is the same response on approved sample ? Just the numbers are different for each chip Is the same ...

Here is the 4 dumped files
First I erased the chips, then I read them.
Fortunately I still have the files which I programmed to these chips 3 years ago (in 2011)!
And they match perfectly with each other!

Thanks EZo Chips should be detected protected or not on Willem/pcb3b. How to check it? Check/clean chip pins, they can be oxidizied loosing connection in ZIF32 socket. They looks fresh but to make sure I applied some solder to 5v gnd /WE /OE / CE Be sure on correct Willem jumpers/dipswitches setting...

Hi I have some AM29F040 which I programmed them with Willem Programmer 3 years ago Now I want to reprogram them but I can't reprogram / erase them at all! I am using a homemade Willem Programmer and I think it is PCB3B with software version 0.97ja Also I tried to use another programmer called FLProg...

set VCC jamper to 5.6 or 6.2 then use USB

What software version do you use? Try to use Version 0.97ja What is your chip number exactly? Have you checked its data sheet? I checked M2732A datasheet and it seems it needs 5v --> VCC / 21v --> VPP for programming. If you set the right settings for your programmer I think you can program it. You ...

I want to make a 16 Bit EPROM Adapter for my Willem Programmer (PCB3B) : http://krauser.persiangig.com/other/WillemFront.JPG http://krauser.persiangig.com/other/WillemBack.JPG I found these designs : (2000/09/20) Toomas Toots (2003/01/17) se-ed.net (2003/07/04) ATH (2004/11/19) EZoFlash Which one is...

Really thanks.

I want to build an EPROM Eraser. Do you think large super bright white LED embeded in a box can erase it?

Hi I have a WILLEM PCB3B and I want to program two types of AT27C080 : http://www.upload-jpg.com/images.php/5dfe91634/DSC00478.JPG I want to make sure that these setting are correct : http://www.upload-jpg.com/images.php/be08f1635/01.PNG JP1 and JP2 --> Normal ************************************ ht...

What message SW return in process termination ? Simply stops without message ? http://up.iranblog.com/images/r0c6t7etf1klhrkikhvc.png Every time the error offset increases! Are you able read chip 100% ? Yes! Do you have any resident programm running, try close it ? What is that?! What is PC operati...

I have a problem : I can program my chip but it is awful : I have to click on "Program Chip" button about 50 times to complete the programming task! For example first time it programs about 3% then second time it would be 5% next time 8% and so on ... I have to do it again and again until it become ...
