This family of devices offers the advantages of all
PIC18 microcontrollers – namely, high computational
performance at an economical price – with the addition
of
memory. In
PIC18F2480/2580/4480/4580 family introduces design
enhancements that make these microcontrollers a

All of the devices in the PIC18F2480/2580/4480/4580
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

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 have been reduced by up to
80%, with typical values of 1.1 and 2.1 μA,
respectively.
standard 75 instructions of the PIC18 instruction
set, PIC18F2480/2580/4480/4580 devices also
provide an optional extension to the core CPU
functionality. The added features include eight
additional instructions that augment indirect and
indexed addressing operations and the
implementation of Indexed Literal Offset
Addressing mode for many of the standard PIC18
instructions.

All of the devices in the PIC18F2480/2580/4480/4580
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

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
