This document contains device-specific information for
the following devices:
• PIC18F2682
• PIC18F2685
• PIC18F4682
• PIC18F4685
This family of devices offers the advantages of all PIC18
microcontrollers
performance at an economical price – with the addition
of high-endurance, Enhanced Flash program memory.
In addition to these features, the PIC18F2682/2685/
4682/4685 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 PIC18F2682/2685/4682/4685
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-
• Lower Consumption in Key Modules: The

block, power consumption during code execution
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 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, PIC18F2682/2685/4682/4685 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.

1.1.2
All of the devices in the PIC18F2682/2685/4682/4685
family offer ten different oscillator options, allowing
users a wide range of choices in developing application
hardware. These options include:
• Four Crystal modes, using crystals or ceramic
• Two External Clock modes, offering the option of
• Two External RC Oscillator modes with the same

• 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
