PIC18F66K80-EPT microcontroller

The YINGHUA PIC18F66K80-EPT is an 8-bit microcontroller in a 64-pin TQFP package. It suits engineers developing embedded control applications that need on-chip peripherals and flash memory. Hobbyists working with PIC18 architecture will also find it useful for custom boards.

Surface-mount installation notes

The TQFP64 footprint requires standard reflow or hot-air soldering equipment and a matching PCB land pattern. Misaligned pins or insufficient solder paste often cause open joints on the fine-pitch leads. Inspect each corner under magnification before powering the board.

Verify your design before ordering

Confirm the PCB layout matches the 64-pin TQFP mechanical outline and pin assignment. Ensure the toolchain supports the PIC18F66K80-EPT device ID and that the operating voltage range fits your supply rails. Check that any required programmer or debugger is compatible with this part.

Questions about this item

How can I verify the PIC18F66K80-EPT is running correctly after soldering the 64-pin TQFP package?

Apply power within the specified voltage range and confirm the oscillator starts; then check that the device responds to a programmer via the ICSP pins and executes a simple firmware loop.

What items are included with the PIC18F66K80-EPT and what must be sourced separately?

The reel or tray contains only the PIC18F66K80-EPT TQFP64 integrated circuits; a PCB, decoupling capacitors, crystal or resonator, programming header and power supply must be provided by the designer.

Which PIC18F66K80-EPT variant should I select for a new 64-pin TQFP design?

The part marked PIC18F66K80-EPT is the 64-pin TQFP version; choose it when the board layout requires that specific package and pin count.
