DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
This family offers the advantages of all PIC18 micro-
controllers – namely, high computational performance at
an economical price – with the addition of high-
endurance Enhanced Flash program memory. On top of
these features, the PIC18F1230/1330 family introduces
design enhancements that make these microcontrollers
a logical choice for many high-performance, power
control and motor control applications.
Peripheral highlights include:
14-bit resolution Power Control PWM module
(PCPWM) with programmable dead-time insertion
The PCPWM can generate up to six complementary
PWM outputs with dead-band time insertion. Overdrive
current is detected by off-chip analog comparators or
the digital Fault input (FLTA).
PIC18F1230/1330 devices also feature Flash program
memory and an internal RC oscillator.

New Core Features
1.1.1
nanoWatt TECHNOLOGY
All of the devices in the PIC18F1230/1330 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
for values.
1.1.2
MULTIPLE OSCILLATOR OPTIONS
AND FEATURES
All of the devices in the PIC18F1230/1330 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.
Two 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).
Two External RC Oscillator modes with the same
pin options as the External Clock modes.
An internal oscillator block which provides an 8 MHz
clock and an INTRC source (approximately 31 kHz),
as well as a range of six user-selectable clock
frequencies, between 125 kHz to 4 MHz, for a total of
eight clock frequencies. This option frees the two
oscillator pins for use as additional general
purpose I/Os.
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
40 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 reference
signal provided by the internal oscillator. If a clock
failure occurs, the controller is switched to the
internal oscillator block, allowing for continued
low-speed 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.
