DEVICE OVERVIEW
This document contains device specific information for
the following devices:
This family offers the advantages of all PIC18
microcontrollers
namely,
high
computational
performance at an economical price – with the addition
of high-endurance, Flash program memory. On top of
these features, the PIC18F/LF1XK50 family introduces
design
enhancements
that
make
these
microcontrollers a logical choice for many high-
performance, power sensitive applications.
1.1
New Core Features
1.1.1
nanoWatt XLP TECHNOLOGY
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
from the Timer1 source or the internal oscillator
block, power consumption during code execution
can be reduced by as much as 90%.
Multiple Idle Modes: The controller can also run
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.
On-the-fly Mode Switching: The power-
managed modes are invoked by user code during
operation, allowing the user to incorporate power-
saving ideas into their application’s software
design.
Low Consumption in Key Modules: The
power requirements for both Timer1 and the
Watchdog Timer are minimized. See
for values.
1.1.2
MULTIPLE OSCILLATOR OPTIONS
AND FEATURES
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
resonators
External Clock modes, offering the option of using
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)
External RC Oscillator modes with the same pin
options as the External Clock modes
An internal oscillator block which contains a
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.
A Phase Lock Loop (PLL) frequency multiplier,
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.
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
monitors the main clock source against a refer-
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.
Two-Speed Start-up: This option allows the
internal oscillator to serve as the clock source
from Power-on Reset, or wake-up from Sleep
mode, until the primary clock source is available.
