Try consulting the datasheet!, max/min specs are near the back - 8V is likely to be far too high, and I would suggest using a 16LF628 if running off 3.3V (although it may just scrape in the spec for an 16F628).
well, isn't 8v outside the maximum operating voltage range of the PIC? I think that would narrow it down rather quickly :lol:
oops, nigel beat me to it. In any case, you could run it off 8v with a 5v regulator, but that's a waste of power if you can run it on 3.3v instead. (linear regulators are inefficient)
When I read evandudes post it said to me "well 8V ISNT outside the maximum operating voltage range of the PIC". He is actually saying it IS outside the maximum rating.
I cant see in chapter 17 where it says what the minimum voltage is?
I believe 3.3v is okay for a regular 16F, however as nigel said you're much better off going to a 16LF (low-voltage version) instead, they are good down to a couple volts.
Actually there is another way how to run PIC from 8V and 3,3V simultaneously (in case you don't need ground to be common).
Because 8-3.3=4.7V you can run the PIC with VDD connected to 8V and VSS connected to 3.3V and the PIC will run just fine.
