YINGHUA PIC18F4431-IPT LQFP44 Microcontroller

This YINGHUA PIC18F4431-IPT is a new microcontroller in an LQFP44 package. It suits engineers and students building motor-control or general-purpose embedded projects. The 44-pin footprint fits standard PCB layouts for prototyping or production runs.

Ideal for custom motor-control boards.

Developers needing on-chip PWM modules for brushless DC or stepper drives will find the peripherals useful. Buyers who want more I/O pins or a different package style should look at other devices. Hobbyists without PIC programming tools may face a steep setup curve.

The LQFP44 package decides PCB compatibility

The 44-lead quad flat pack determines the board footprint and soldering method. Verify that your layout matches this pin count and pitch before ordering. No other package variant is included in this listing.

Questions about this item

What PCB footprint matches the 44-pin LQFP package?

The device uses a 44-lead LQFP package that requires a matching 44-pin footprint on the board.

How is the PIC18F4431-IPT soldered and what step is often missed?

It is surface-mounted; the critical step is applying the correct reflow profile for the LQFP body to avoid cold joints.

When will the on-chip Flash need to be reprogrammed?

The Flash memory can be rewritten many times; reprogramming is only needed when firmware updates are required.
