I'm thinking for now I'll order a 18f4620 and a PIC18F26K20, based on what little I have to go on. No chip had a vote from more than one expeirienced user so I just the ones that had 1 expeirienced vote and 1 newb vote, then I picked one from that list that was in the most common use so i could get it running more easily and one that had the newest functionality.
I figure that PDIP 600mil means its .6 inches wide, but what does SPDIP mean? I just need to be sure it can fit in a breadboard with .1in spacing.
Edit: ok, so spdip seems to have a smaller pitch between the pins. I'm trying to figure out if the PIC18F26K20 even comes in a DIP that will fit a breadboard.
