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 enhanced Flash program memory and a
high-speed 10-bit A/D Converter. On top of these
features,
the
PIC18F2331/2431/4331/4431
family
introduces design enhancements that make these micro-
controllers a logical choice for many high-performance,
power control and motor control applications. These
special peripherals include:
14-Bit Resolution Power Control PWM module
(PCPWM) with Programmable Dead-Time Insertion
Motion Feedback Module (MFM), including a
3-Channel Input Capture (IC) module and
Quadrature Encoder Interface (QEI)
High-Speed 10-Bit A/D Converter (HSADC)
The PCPWM can generate up to eight complementary
PWM outputs with dead-band time insertion. Overdrive
current is detected by off-chip analog comparators or
the digital Fault inputs (FLTA, FLTB).
The MFM Quadrature Encoder Interface provides
precise rotor position feedback and/or velocity
measurement. The MFM 3x input capture or external
interrupts can be used to detect the rotor state for
electrically commutated motor applications using Hall
sensor feedback, such as BLDC motor drives.
PIC18F2331/2431/4331/4431 devices also feature
Flash program memory and an internal RC oscillator
with built-in LP modes.

New Core Features
1.1.1
nanoWatt Technology
All of the devices in the PIC18F2331/2431/4331/4431
family incorporate a range of features that can signifi-
cantly 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 are
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.
Lower Consumption in Key Modules: The
power requirements for both Timer1 and the
Watchdog Timer have been reduced by up to
80%, with typical values of 1.1 and 2.1
A,
respectively.
1.1.2
MULTIPLE OSCILLATOR OPTIONS
AND FEATURES
All of the devices in the PIC18F2331/2431/4331/4431
family offer nine 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 (approxi-
mately 31 kHz, stable over temperature and VDD),
as well as a range of 6 user-selectable clock
frequencies (from 125 kHz to 4 MHz) for a total of
8 clock frequencies.
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.
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.
