Matt, Are there any other 18F's with a Vbat pin that come in a smaller =20 package -- 28-pins are ideal, but 44 is workable. 100 pins will be =20 tough to fit on the board. Also, the PIC selector tool did not allow me to chose RTC as an =20 option. Is there some way to search for these? Cheers, -Neil.
