This document contains device specific information for
the following devices:
This family offers the advantages of all PIC18 micro-
controllers – namely, high computational performance
at an economical price – with the addition of high-
endurance, Enhanced Flash program memory. On top
of these features, the PIC18F2420/2520/4420/4520
family introduces design enhancements that make
these microcontrollers a logical choice for many high-
performance, power sensitive applications.
1.1
1.1.1
All of the devices in the PIC18F2420/2520/4420/4520
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
• Multiple Idle Modes: The controller can also run
• On-the-fly Mode Switching: The power
• Low Consumption in Key Modules: The

can be reduced by as much as 90%.
with its CPU core disabled but the peripherals still
active. In these states, power consumption can be
reduced even further, to as little as 4% of normal
operation requirements.
managed modes are invoked by user code during
operation, allowing the user to incorporate power-
saving ideas into their application’s software
design.
power requirements for both Timer1 and the
Watchdog Timer are minimized. See

Preliminary
1.1.2
All of the devices in the PIC18F2420/2520/4420/4520
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
• Two External Clock modes, offering the option of
• Two External RC Oscillator modes with the same
• An internal oscillator block which provides an
• A Phase Lock Loop (PLL) frequency multiplier,
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: This option constantly
• Two-Speed Start-up: This option allows the
resonators

clock output) or one pin (oscillator input, with the
second pin reassigned as general I/O)

8 MHz clock and an INTRC source (approxi-
mately 31 kHz), as well as a range of 6 user
selectable clock frequencies, between 125 kHz to
4 MHz, for a total of 8 clock frequencies. This
option frees the two oscillator pins for use as
additional general purpose I/O.
available to both the high-speed crystal and inter-
nal oscillator modes, which allows clock speeds of
up to 40 MHz. 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.

ence signal provided by the internal oscillator. If a
clock failure occurs, the controller is switched to
the internal oscillator block, allowing for continued
low-speed operation or a safe application
shutdown.
