I am using the latest top application. When i try to program AM2732DC I try many different voltage settings and all fails to program the chip fully. Sometimes it stops close to the end. I have tried

17.5v 5ms
17.5v 40ms
17.5v 200us
24v 40ms
24v 200us

No setting will program completely, sometimes i can see if programmed a fair way othertimes some bits look wrong but always it won't complete.

I'm not using an external power supply just USB.

The TOP programmers do not work well on 27XX series NMOS ERPOMs.
