PIC18F4431-EPT LQFP44 microcontroller

The PIC18F4431-EPT is an 8-bit microcontroller in a 44-pin LQFP package. It suits engineers building motor-control or general-purpose embedded systems. New stock from YINGHUA is available for prototype and production runs. The device integrates core peripherals for real-time applications.

44-pin LQFP package constraints

The LQFP44 footprint fixes the I/O count at 44 pins and requires surface-mount assembly. Pin spacing limits manual rework and demands precise PCB layout. Designers must route all signals within this fixed pin budget. No larger or smaller package option is offered for this part number.

Replaces earlier 40-pin PIC18F parts

Moving from a 40-pin DIP or 44-pin PLCC device adds four extra I/O lines and a thinner profile. The jump is worth it when board height is restricted or when the additional pins simplify routing. Existing 40-pin code ports with minor register changes. Teams staying with through-hole assembly cannot use this package.
