This family offers the advantages of all PIC18
microcontrollers
performance at an economical price – with the addition
of high-endurance, Flash program memory. On top of

All of the devices in the PIC18F/LF1XK50 family incor-
porate 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

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-

1.1.2
All of the devices in the PIC18F/LF1XK50 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
• External Clock modes, offering the option of using
• External RC Oscillator modes with the same pin
• 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
resonators
two pins (oscillator input and a divide-by-4 clock
output) or one pin (oscillator input, with the sec-
ond pin reassigned as general I/O)
options as the External Clock modes
16 MHz HFINTOSC oscillator and a 31 kHz
LFINTOSC oscillator which together provide 8
user selectable clock frequencies, from 31 kHz to
16 MHz. 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 48 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 LFINTOSC. If a clock
failure occurs, the controller is switched to the
internal oscillator block, allowing for continued
operation or a safe application shutdown.
