I’m not sure if this question has been posed yet, but is it possible to use the PIC18LF instead of the PIC18F??
On another note - Is the Core design for the 18F the same as for the 16F?
not sure on the first q, but i believe all that needs changin from the original core to the 18F version is to swap the 20MHz xtal for a 10Mhz one…

Yes, the PIC18LF452 is ok, it’s nearly the same like a common PIC18F452, but the temperature range meets only the industrial conditions (-40°C .. 85°C instead of -40°C .. 125 °C). However, the PIC doesn’t get hot like a pentium CPU, so don’t hesitate to order this one! 
Best Regards, Thorsten.
