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

1.1.2
All of the devices in the PIC18F2XK20/4XK20 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 contains a
• 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)

an external crystal or clock circuit.
