If you have access to an xray machine you may be able to do it with a P chip. I
have heard various funny stories of people using eprom devices to develop
mannequins for teaching trainee doctors to interpret xrays, and after a while
the eproms get erased. Dosage rate of xrays unknown however - you will have to
experiment. next time you go to the dentist, take a mouthful of chips to erase!

I have a ceramic windowed FLASH emulator chip for one of their parts.  It was an
early engineering sample.
Yes, both UV and Flash!

OK well thats good to know.  Then we can expect the usual Erasable part
sooner or later.  Hopefully not later Christmas!

On all their other parts, the OTP and UV-erasable parts are cut from the
same wafers.  The OTP parts are simply packaged in the much-cheaper plastic
packages rather than the expensive ceramic windowed ones.

In addition to being much cheaper, the plastic packages are processed on
more-highly-automated assembly facilities.  This generally means that their
backlogs are shorter.  So it is highly likely that the erasable parts are on
the way, but the plastic ones have simply popped out of the machine first.
While it's conceivable that there is a process reason why they aren't
erasable, or that Microchip simply decided that there wasn't enough demand
to go to the trouble of making the windowed ones, that's not their usual
style.  They do make a point of supporting developers as part of a marketing
philosophy that has worked for them all along.

Engineering samples of new chips often show up first as OTP's in plastic
packages, just because the process is quicker.
