Product Identity

The YINGHUA PIC18F442-I PT is an 8-bit microcontroller in a 44-pin LQFP package. It is intended for engineers and hobbyists building embedded control applications. The device integrates flash program memory and peripherals suitable for general-purpose tasks. Supplied in new condition, it is ready for prototype or production assembly.

Suitability

This part suits developers working with the PIC18F architecture who need the specific 44-pin footprint and feature set. It is not suitable for designs requiring a different pin count, package style, or core architecture. Buyers needing higher memory density, faster clock speeds, or integrated analog modules beyond this device's specification should evaluate alternative microcontrollers.

Deciding Specification

The LQFP44 package defines the physical footprint and pin-out for the printed circuit board layout. Verify that the 44-lead outline matches the board design before ordering. The February 2025 listing date confirms current manufacturer availability for new designs. Ensure the device electrical characteristics meet the application voltage and temperature requirements.

Questions about this item

How much heat does the 44-pin LQFP package dissipate during continuous operation?

The LQFP44 surface-mount package has a typical thermal resistance that lets the die stay within its rated junction temperature under normal 5 V operation; a small copper pour on the PCB is usually enough to handle the heat.

What external components are needed to make the PIC18F442-I run?

You must supply a 5 V power rail, a crystal or ceramic resonator up to 20 MHz with two load capacitors, a pull-up resistor on the MCLR pin and decoupling capacitors on each VDD/VSS pair.

Will code written for an older 18-series PIC with 44 pins port directly to this device?

The core instruction set and peripheral registers are the same across the PIC18 family, so existing C or assembly firmware recompiles without changes provided the target device has the same peripheral mix and memory map.
