fast view of those :

PIC16F870 PIC16F872:
  • 22 i/o
    2K code memory space
    need external crystal
    64 bytes of internal EEPROM
    6.29$ CAN
Probably would need to be this one since the other isn't supported by pcb from what I can tell. Still leaves extra I/O ports and that would be okay as I could add another couple LEDs which I had previously left off due to available ports.

Depending on the physical size of one of these and the chipcorder there may be room if the crystal is small. From what I can tell looking at some specs the surface mount chips are usually about 10x17 mm which is well within the realm of putting a couple on a 1x2 inch board side where there isn't going to be any LEDs or switches in the way.

I'm at information overload for tonight now so I'll check into sizes tomorrow then try to get a list together for the breadboarding of this. I have to work on it slow. Too many other pressing obligations and I don't want to stress myself out trying to learn it in a day.

At least I can probably make the LED's turn on and off the way I want so that's a start! :-)
