Microcontroller for embedded projects

The YINGHUA PIC18F4680-EPT is an 8-bit microcontroller supplied in a 44-pin LQFP package. It targets engineers and hobbyists developing embedded control applications that need integrated peripherals and flash memory. The device suits new designs where a compact surface-mount footprint is required. It arrives in new condition ready for prototype or production use.

Upgrade from smaller PIC18 variants

This part replaces earlier PIC18 devices that offer less program memory or fewer I/O pins. The jump is worthwhile when your firmware exceeds the limits of 28-pin or 40-pin alternatives and you need the extra resources in the same architecture. Designers staying within the PIC18 family avoid a full architecture migration. The 2026 listing date confirms current production availability.

Verify toolchain and voltage rails

Confirm your compiler and programmer support the PIC18F4680-EPT before ordering. Check that your board provides the correct supply voltage for the device and that the 44-pin LQFP footprint matches your PCB layout. Ensure the oscillator source you plan to use is compatible with the chip's clock options. Validate thermal and power budgets for the target enclosure.

Questions about this item

What footprint and pin count does the PIC18F4680-EPT LQFP44 need on the PCB?

The device uses a 44-pin LQFP surface-mount package, so the board must provide a matching 44-pin LQFP footprint with correct pad dimensions and pitch.

How is the PIC18F4680-EPT LQFP44 soldered onto the board, and what step is often missed?

It is reflow-soldered as a standard SMT component; the step frequently missed is applying the correct solder-paste stencil thickness and verifying paste volume before placement.

What long-term replacement consideration applies to the PIC18F4680-EPT LQFP44?

As a microcontroller in a 44-pin LQFP package, it will need replacement only if the application firmware changes require a different part or the device reaches end-of-life.
