PIC18(L)F1XK22

1.1.2

MULTIPLE OSCILLATOR OPTIONS

AND FEATURES

1.0

DEVICE OVERVIEW

This family offers the advantages of all PIC18

microcontrollers namely, high computational

performance with the addition of high-endurance,

Flash program memory. On top of these features, the

All of the devices in the PIC18(L)F1XK22 family offer

ten different oscillator options, allowing users a wide

range of choices in developing application hardware.

These include:

introduces

design

enhancements that make these microcontrollers a

logical choice for many high-performance, power

sensitive applications.

• 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

second pin reassigned as general I/O)

New Core Features

1.1.1

XLP TECHNOLOGY

• External RC Oscillator modes with the same pin

options as the External Clock modes

All of the devices in the PIC18(L)F1XK22 family

incorporate a range of features that can significantly

reduce power consumption during operation. Key

items include:

• An internal oscillator block which contains a

16 MHz HFINTOSC oscillator and a 31 kHz

LFINTOSC oscillator which together provide eight

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.

• 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.

• A Phase Lock Loop (PLL) frequency multiplier,

available to both the high-speed crystal and

internal oscillator modes, which allows clock

speeds of up to 64 MHz. Used with the internal

oscillator, the PLL gives users a complete

selection of clock speeds, from 31 kHz to 64 MHz

– all without using an external crystal or clock

circuit.

• 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

Section 26.0 “Electrical Specifications”

for values.

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

reference 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.
