Like all Microchip PIC18 devices, members of the
PIC18F2331/2431/4331/4431 family are available as
both standard and low-voltage devices. Standard
devices with Enhanced Flash memory, designated with
an “F” in the part number (such as PIC18F2331),
accommodate an operating V
Low-voltage parts, designated by “LF” (such as
PIC18LF2331), function over an extended V
of 2.0V to 5.5V.
