HI guys ,

i have application where power is really an issue on small batteries and i have used only the 18F version upto now , is there a real power saving when using the 18LF version of the chips ?

application uses 3.3volts
cheers

I don't think there is any power saving per se, LF devices allow a lower Vdd for a given speed.

I can't quote chapter and verse, but in electrical specs in the data sheet, the tables apply to both LF and F.

ok thanks , thats what i thought , the only power saving maybe no need for the internal regulator and its very small load

And Ohms law will help you a bit with fixed loads.
