DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
This family offers the advantages of all PIC18
microcontrollers – namely, high computational perfor-
mance at an economical price – with the addition of
high-endurance, Enhanced Flash program memory.
On top of these features, the PIC18F2423/2523/4423/
4523 family introduces design enhancements that
make these microcontrollers a logical choice for many
high-performance, power-sensitive applications.
1.1
New Core Features
1.1.1
nanoWatt TECHNOLOGY
All of the devices in the PIC18F2423/2523/4423/4523
family incorporate a range of features that can signifi-
cantly reduce power consumption during operation.
Key items include:
Alternate Run Modes: By clocking the controller
from the Timer1 source or the internal oscillator
block, power consumption during code execution
can be reduced by as much as 90%.
Multiple Idle Modes: The controller also can run
with its CPU core disabled and the peripherals still
active. In these states, power consumption can be
reduced even further, to as little as 4% of normal
operation requirements.
On-the-Fly Mode Switching: The power-managed
modes are invoked by user code during operation,
allowing the user to incorporate power-saving ideas
into their application’s software design.
Low Consumption in Key Modules: The power
requirements for both Timer1 and the Watchdog
Timer are minimized. See Section 4.0 “Electrical
1.1.2
MULTIPLE OSCILLATOR OPTIONS
AND FEATURES
All of the devices in the PIC18F2423/2523/4423/4523
family offer ten different oscillator options, allowing
users a wide range of choices in developing application
hardware. These include:
Four Crystal modes, using crystals or ceramic
resonators.
Two External Clock modes, offering the option of
using two pins (oscillator input and a divide-by-4
clock output) or one pin (oscillator input, with the
second pin reassigned as general I/O).
Two External RC Oscillator modes with the same
pin options as the External Clock modes.
An internal oscillator block that offers eight clock
frequencies: an 8 MHz clock and an INTRC source
(approximately 31 kHz), as well as a range of six
user-selectable clock frequencies, between
125 kHz to 4 MHz. This option frees the two
oscillator pins for use as additional general
purpose I/O.
A Phase Lock Loop (PLL) frequency multiplier,
available to both the High-Speed Crystal and
Internal Oscillator modes, allowing clock speeds
of up to 40 MHz from the HS clock source. Used
with the internal oscillator, the PLL gives users a
complete selection of clock speeds, from 31 kHz
to 32 MHz, all without using an external crystal or
clock circuit.
Besides its availability as a clock source, the internal
oscillator block provides a stable reference source that
gives the family additional features for robust
operation:
Fail-Safe Clock Monitor: Constantly monitors
the main clock source against a reference signal
provided by the internal oscillator. If a clock failure
occurs, the controller is switched to the internal
oscillator block, allowing for continued operation
or a safe application shutdown.
Two-Speed Start-up: Allows the internal oscillator
to serve as the clock source from Power-on Reset,
or wake-up from Sleep mode, until the primary clock
source is available.
