YINGHUA PIC18F86J72-I PT TQFP80 microcontroller

The YINGHUA PIC18F86J72-I PT is an 8-bit microcontroller in an 80-pin TQFP package. It targets engineers developing embedded control applications that require integrated peripherals and on-chip memory. The device is supplied new and suits prototype or production board assembly. It fits designs needing the specific PIC18F86J72-I PT part number.

Surface-mount TQFP80 installation requires reflow

Installing the PIC18F86J72-I PT demands standard surface-mount reflow techniques for the 80-pin TQFP footprint. Accurate paste stencil alignment and thermal profiling prevent solder bridges between fine-pitch leads. Moisture sensitivity handling is critical; bake parts if floor life limits are exceeded before reflow. Incorrect orientation or insufficient solder paste volume are the most common assembly faults.

Verify PCB footprint and voltage rails before

Confirm the PCB land pattern matches the 80-pin TQFP package dimensions and pin pitch used by this device. Ensure the board provides the correct core and I/O voltage levels specified in the datasheet. Check that programming and debug interfaces connect to the appropriate pins for in-circuit firmware development. Validate clock source and reset circuitry compatibility with the microcontroller requirements.

Questions about this item

How can I confirm the PIC18F86J72-I PT TQFP80 is functioning after soldering it to the board?

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

What is included with the PIC18F86J72-I PT TQFP80 and what must be sourced separately?

The tray contains the 80-pin TQFP microcontroller only; a PCB with matching footprint, decoupling capacitors, a crystal or resonator, and an ICSP header for programming are not included.

Which package variant of the PIC18F86J72-I should I select for a surface-mount design?

Choose the PT suffix version supplied in the 80-pin TQFP package, as it is the only variant listed for this part number.
