I have a hardware project running with a 16F886 powered by a LI ION battery at maximum 4.2V I'd like to drop in a PIC18F26K20 for increased ram.
I noticed in the datasheet it is normally for 3.6V the absolute maximum ratings for pins are 4.5v. Will i Hurt this pic when i continually power it at 4.2v dropping to 3.5v when the battery is low?
Is it correct I do not have to bank switch for accessing all the ram on this 18F... ?
Any other things I need to watch?
