This document contains device-specific information for
the following devices:
The PIC18F4553 family of devices offers the advan-
tages of all PIC18 microcontrollers – namely, high
computational performance at an economical price –
with the addition of high-endurance, Enhanced Flash
program memory. In addition to these features, the
PIC18F4553 family introduces design enhancements
that make these microcontrollers a logical choice for
many high-performance, power sensitive applications.

Note:
implements a 12-bit A/D Converter. The A/D
Converter incorporates programmable acquisi-
tion time. This allows for a channel to be selected
and a conversion to be initiated, without waiting
for a sampling period and thus, reducing code
overhead.

Members of the PIC18F4553 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 PIC18F2458),
accommodate an operating V
Low-voltage parts, designated by “LF” (such as
PIC18LF2458), function over an extended V
of 2.0V to 5.5V.
