Did you check the datasheet? I don't need to check it, but for you I'll do it..

Ah. It's exactly the same as in the thread I saw a week or two ago. If you
take a look at Table 15-1 on page 150 of the current 16F873/4/6/7 datasheet
DS30292C you'll find that the minimum operating Vdd is 4.0 volts.

So according to the table, the probability is 0 percent that the part will
run. The reality of the situation is that it may function at 3.3V. However
it'll be out of spec.

Now if you get a PIC16LF876, which Digikey has in stock for $8.08 in singles,
the probability goes up to 100 percent according to table 15-2 on the same
page.

The datasheet is the source of all knowledge young one.

Use it wisely. Use it. ;-)
