PIC16LF1939-IPT microcontroller

The PIC16LF1939-IPT is a new semiconductor component supplied by YINGHUA for electronic designs. It comes in a 44-pin LQFP package suitable for surface-mount assembly. Engineers select this IC when a low-power PIC architecture fits the project requirements. The part is ready for integration into custom circuit boards.

Replacing earlier PIC revisions

Designers adopt the PIC16LF1939-IPT when an existing layout needs the specific peripheral set or memory map this model provides. The jump is worth it if the firmware can use the updated core features without a full redesign. Migration stays straightforward when pin functions align with the previous device. Verify the datasheet to confirm compatibility before ordering.

Fitting the component into a build

The LQFP44 footprint demands a matching PCB land pattern and careful reflow soldering. Decoupling capacitors must be placed close to the supply pins for stable operation. The device frees board space compared to larger packages, allowing denser layouts. Ensure the programming header matches the ICSP interface for in-circuit firmware updates.

Questions about this item

What PCB footprint does the LQFP44 package need?

The LQFP44 package requires a 44-pin quad flat no-lead footprint on the circuit board.

How is the PIC16LF1939-IPT mounted, and what step is often missed?

It is surface-mounted onto the PCB pads; the step often missed is applying the correct solder-paste volume and reflow profile for the fine-pitch leads.

When will the PIC16LF1939-IPT need replacement?

The device is rated for industrial temperature operation; replacement is only needed if it suffers electrical overstress or reaches its specified endurance limit.
