Microcontroller for Embedded Control

The PIC18F85J90-IPT is an 8-bit microcontroller intended for embedded control tasks in new electronic designs. It targets engineers who need a PIC18 core with integrated peripherals for industrial or consumer applications. The 80-pin TQFP package suits surface-mount assembly on custom printed circuit boards. Buyers who require a different core architecture or higher pin count should look elsewhere.

Surface-Mount TQFP Package

The 80-TQFP package provides a compact footprint for dense board layouts and automated reflow soldering. Its gull-wing leads allow visual inspection of solder joints after assembly, aiding quality control in production. The package dimensions match standard 80-pin TQFP land patterns, simplifying PCB design. Designs that demand through-hole mounting or a smaller lead pitch cannot use this device directly.

Upgrade Path for PIC18 Projects

This part replaces earlier PIC18 variants when a design needs the specific peripheral mix and memory configuration identified by the 85J90 designation. The jump is worthwhile when existing code can migrate to the 18F85J90 feature set without major rewrites. Projects locked to a different pin count or instruction set will not benefit from a direct swap.

Questions about this item

What does the 80-TQFP designation tell me about the package interface?

The 80-TQFP marking means the device uses an 80-lead thin quad flat pack, giving 80 connection points in a surface-mount footprint.

What board space and layout does the 80-lead TQFP require?

The 12 mm by 12 mm body needs a matching land pattern with 80 pads and room for lead inspection after soldering.

How is this IC mounted, and which step causes the most rework?

It is surface-mounted by reflow; the step most often done wrong is applying too much paste, which bridges the fine-pitch leads.
