39VF160 Flash what WILLEM I need to buy?

Hello there mates ,,

Im new here in this board by the way im Rey from Philippines
I like to backup the data from chip 39VF160 to another chip what Programmer verion and adapter I need to buy ..

Please assist me mates and 1 thing the Willem Programmer can copy the data from 1 chip to another ..

Example .. I have 1 chip working .. and I like to save or backup the data from working chip and write to another chips ?

can i do that mates?

Thanks a lot .. Thanks thanks ..

I appreciate answers ..

Best Regards,

Hi Rey,

What you want to do is possible, but you'll have to remove the chip from it's board.

All Willem programmers will require a 16bit TSOP48 adapter to read/program that chip.  If you can make your own boards, EzoFlash is a good option.  Otherwise pick a Willem type programmer and buy an adapter like Sivava's T10.

You're device is VCC=2.7-3.6V; you'll want to look at how programmers you consider implement low voltage.

Most insert diode(s) to drop the nominal 5V to 3.6V to the device being programmed.  Unfortunately, most still drive the device inputs at 5V (this can cause electromigration -- i.e. premature device failure, if not immediate).  And the device underdrives the programmer inputs.  The advantage, if you can call it that, is that this implementation drives the parallel port at the proper voltage.

The Willem 4.5 has a TSOP48 socket that only supports byte wide devices (or 16bit devices with a byte mode).  It implements low voltage on the programmer properly, but doesn't have a level shifter to drive the parallel port at 5V and protect the programmer inputs from electromigration.  I can tell you how to build a level shifter for this programmer if you go this route.

The Willem 4.1 programmer did this the best (only needed 2 pull-up resistors to make it better), but it's no longer being sold.  If you could find one; it with a T10 type adapter would be the best.

HTH,
Dennis

Hello Dennis,

Firstly Thank you very much for fast reply ... I always monitor on this thread..

Okay ... I will buy T10 from SIVAVA Company ( Thank you also for giving the link   )

I think I dont find Willem 4.1 Programmer that why I go to Willem 4.5 Programmer by the way from SIVAVA Company what Package I prefer to this project?

Package 1?
Package 2?
Package 3?
Package 4?
Package 5?

after I buy those need programmer and adapter ... can you assist me how to do this .. I know it is difficult at frist ...  Im hoping that anyone assist me about this .. thanks,.

Thanks a lot mate ... for the well explain answers

Best Regards,

Hi Rey,

Which PCB4.5C package you should buy depends on what other devices you plan to program.

Here's my disclaimer.  I wouldn't buy a PCB4.5C because it doesn't implement low voltage support correctly.  It has two diodes near the ZIF socket that reduce VCC to the programming sockets, but continues to operate the programmer at 5V.  I don't like the complexity added by the step-up regulator used for VPP and I'd replace it with a linear regulator if I was going to program EPROMs that require VPP > 12.5V.  I'd never connect the USB power option to a computer.  That programmer and most other PCB3 and Willem variants will have voltage drop problems with NMOS EPROMs (can draw up to 100mA from VCC) and other devices (NMOS microcontrollers, NVRAMs, etc).  It doesn't have low VCC options needed for blank verifying EPROMs (though you can use the 3.6V diode hack and short one of the diodes; this will give you around 4.3V).

That programmer will work for the device you intend to program, but other devices can be problematic.

I think a better choice would be to find a Willem 4.1 to use with the Sivava T10 adapter (you'll need a different cable to connect high order address lines because pin order is different).  My second choice would be Willem 4.5 (it won't support serial devices, 27SF* erase, NMOS EPROMs, EPROMs requiring VPP > 12.5V).  It also needs a little work on level shifting when not operating at VCC=5V.  PCB4.5C would be my third choice.  It's the best of the PCB3 variants, but Sivava is trying to close their design and the software that was previously open source and continues to ignore flaws in their hardware and software...  So the Activist in me says to boycott their products whenever possible.

HTH,
Dennis

Hello there mate ... My Willem 4.1 Programmer Arrive today ..

Im waiting for the T10 from Sivava Company ..

Any modification move for my Project ...

I like to Copy Content of my Working 39VF160 to save in my hard drive ... so that I will find blank 39VF160 ic to write ...

Please help me mates ... Thanks in advance ..

Im looking also 1pc  Willem version 4.1 please send me pm
