That part seems to be a real problem for Microchip. It has had a parade of strange and unusual things wrong with it. This is a part I stay away from. The 16F88, 16F648A, and a few others have a good history of being solid parts and use the same footprint. Unless you really really need the extra oomph of a PIC 18, those are better and probably cheaper choices. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
