Hi, does anyone know the actual difference between a PIC LF and F version?
Say between a 18F452 and 18LF452? The data sheet shows everything pretty much identical except the LF version has a chart showing oscillator zone being ok at lower voltages.
I'm interested in the exact reason one part is F and another is LF? Is the LF manufactured differently, and if so what are the differences?
Or did the LF part just go through an extra test to check it was ok running at lower voltage and then got marked as LF?
The reason is that I need a couple of PICs to run from 3.0v (hobby project) and don't have any LF parts in stock at the moment and they take 14 days to get here and cost me shipping etc.
Also if anyone has real world experience using a F part at 3v Vdd or anything like that it would be nice to hear from you.
