What is the difference between the PIC18LF4620 and 18F4620
PostPosted: Thu Jun 25, 2009 3:42 pm     Reply with quote
I can't seem to find any datasheet for the PIC18LF4620. Instead all the links seem to point at the datasheet for the PIC18F4620. Anyone know what the difference is between them? Do they both use the PCH compiler?

Thanks.

The LF version, is included in the standard data sheet.
Look at the electrical characteristics tables.
The LF will operate at low clock rates, right down to 2v There are a couple of 'caveats', with regard to the ADC maximum rate supported even at higher voltages on this version though.

Search for the words "LF" in the PIC data sheet. You will find
statements like this:
Quote:
Low-voltage parts, designated by “LF” (such as
PIC18LF2620), function over an extended VDD range
of 2.0V to 5.5V.


Then go to the Electrical Characteristics section of the PIC data sheet
and search for "LF" down there. You will find lots of diagrams and
tables for the LF chip.
