PIC18F4685-IPT LQFP44 microcontroller

The PIC18F4685-IPT LQFP44 is a new 8-bit microcontroller in a 44-pin low-profile quad flat package. It provides on-chip program and data memory for embedded control tasks. The part is supplied as a single component for board-level integration.

Engineers developing custom control boards

This device suits engineers who need an 8-bit core with integrated peripherals for a specific board design. It is not for buyers who want a ready-to-run development kit or a module with pre-soldered headers. It is also not for hobbyists who require Arduino-compatible form factors or built-in USB bootloaders.

44-pin LQFP package footprint

The 44-pin LQFP package fixes the PCB footprint and pin-out for the design. Layout must match this pin count and spacing exactly; a different package variant will not fit the same pads. Verify the mechanical drawing before committing to fabrication.

Questions about this item

How do I solder the PIC18F4685-IPT onto a PCB with its 44-pin LQFP package?

Align the 44 pins with the matching footprint, apply flux, then solder each pin using a fine-tip iron or hot-air rework station; the step often missed is inspecting all 44 joints under magnification for bridges before powering the board.

What maintenance will the PIC18F4685-IPT require after installation?

The device is a sealed 44-pin LQFP IC with no moving parts or user-serviceable elements, so no scheduled maintenance is needed; replacement is only necessary if the chip itself fails.

What thermal limit appears first when the PIC18F4685-IPT runs continuously at full load?

The LQFP44 package dissipates heat through its 44 leads and exposed pad area, so the junction temperature ceiling is reached before any external component limit under sustained operation.
