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 PIC18F4321 family introduces design
enhancements that make these microcontrollers a logical
choice for many high-performance, power sensitive
applications.

1.1.1
All of the devices in the PIC18F4321 family incorporate
a range of features that can significantly 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

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.
power-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
Section 26.0 “Electrical Characteristics” for
values.

1.1.2
All of the devices in the PIC18F4321 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
• Two Internal Oscillator modes which provide
• 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

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

6 user-selectable clock frequencies, between

One or both of the oscillator pins can be used for
general purpose I/O.
available to both the high-speed crystal and
internal 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.
