This document contains device-specific information for
the following devices:
This family offers the advantages of all PIC18
microcontrollers
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,
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
• Motion Feedback Module (MFM), including a
• 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.

Key items include:
• Alternate Run Modes: By clocking the controller
• Multiple Idle Modes: The controller can also run
