Does this mean that if I program them (OTP's) with a Picstart Plus some may
not work across the entire 2.5-5.5V range?? I have a very small run that I'd
rather not buy the PROMATE II parts. I am still not clear on the subject. Is
it the erasing, the programming or both that is important to ensure
operation over the full range??

Am I correct in saying the ProMate programs at 5V levels then verifies at
the set extremes? I's hate to think that some OTP's may fall out after
programming because they weren't erased properly.

Thanks,

To which Andrew Warren Replied:

    Yes and yes... You can assume that they're blank when you get
    them, and you should verify them (after they're programmed) at
    the voltage extremes.
