1.0 DEVICE OVERVIEW

This document contains device specific information for

the following devices:

• PIC18F13K50

• PIC18LF13K50

• PIC18F14K50

• PIC18LF14K50

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

Section 27.0 “Electrical Specifications”

for values.

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.
