Click to expand.Unfortunately, you've bought the infamous 'Enhanced Universal Willem EPROM Programmér'. In my knowledge (I have one), it is useless for reading or writing EPROMs. That being mentioned, you can downIoad software from siváva.com. I'm begin with version 0.97ja It't been awhile since I've believed about that programmer, but I do remember that that design uses the output of an OP Amplifier to provide some of thé voltages.

Because óf that, it cán just offer about 25mA of present. Because they usually sand the part numbers from the IC's on that alternative, it's tough to enhance. But, as I mentioned, that specific variant is certainly useless. Wonderful idea, but they failed on the implementation. Click to broaden.If you're going to program sufficient EPROMs to justify not getting somebody else system them for yóu and you would like to remain with an affordable Willem centered programmer, any PCB3 version, ATH3.1, or Willem 4.1 can be produced to function.

Just recognize that all PCB3 versions use a step up regulator to generate VPP and they opt for an affordable shaped inductor that saturatés at a low present. That means they struggle to create VPP >12.5V, some also struggle to supply 12.5V. The only Willem variant I would consider buying is usually the 4.1 which has a relay to switch VCC so it can handle NMOS EPROMs (2716, 2732, etc) and increased capability CMOS EPROMs (bigger than 1Mw). Regrettably it's simply no longer accessible in a commercial sense.

I offered Willem's i9000 developers in the Us all and have small quantity of uncovered boards I'd market at price if you're fascinated in putting together your personal. All of the elements needed should end up being readily accessible; most of what you require is usually on the coder you bought. Since Willem programmers are usually hobbyist degree, they suppose you understand something about development EPROMs so you can perform it dependably. I'd become content to respond to any questions you might have.

Hi Bob, I wear't have any suggestions for additional developers. Willem developers fulfill my requirements; though I would like software program to be more open so the algorithms can end up being analyzed. I work around that unknown by verifying programmed devices at several voltages (all talked about in standard programming algorithms). Spending hundreds of bucks for a commercial programmer doesn'testosterone levels necessarily suggest it plans devices reliably.

I experienced a 'expert' EPROM coder and uncovered the tough method thát it didn't vérify erase margin correctly. When I contacted the firm, they just told me my model was outdated and that I should purchase a newer model. Click on to expand.Like most issues, it is dependent. It is dependent on whether they've improved the energy supply circuitry which offers been recently a a weakness in many Willem programmers and what devices you desire to plan.

I would talk to the Seller if the programmer can supply VCC ánd VPP at thé required voltages and currents for reading/programming devices. For VCC, I'd check out for 4.2, 5.0, 6.0, 6.25 with a fall of 0.1V or less at 50mA new. For VPP, I'd check out for 12.75, 21.0, 25.0 with a fall of much less than 0.25V at 50mA. If they say they can plan NMOS EPROMs, they need to end up being able to provide VCC at 100mA new.

If you buy one that can't perform this, come back it as it's unsuitable for use as a programmer. Proper development of a 5V (10% threshold) 27C512 requires VCC choices of.
