Product Identity

The YINGHUA PIC18F46K42-I PT TQFP44 is a new 44-pin microcontroller in a TQFP package. It suits engineers developing embedded control applications that require this specific part number. The component is stocked as a standalone semiconductor for prototype or production use. Buyers needing a different pin count or package style should select another device.

Compatibility Check

Verify that your PCB footprint matches the 44-lead TQFP outline and pin pitch before ordering. Confirm the operating voltage range and peripheral set align with your firmware requirements. Ensure your programmer or debugger supports this PIC18F series device for flashing and debugging. Cross-reference the manufacturer datasheet for electrical characteristics and errata.

Build & Connectors

The TQFP44 surface-mount package requires reflow or hot-air soldering equipment for reliable assembly. The 44 leads provide access to I/O ports, power, and programming pins in a compact square body. Pin spacing demands careful stencil design and inspection to avoid bridging during assembly. The part is supplied new and ready for immediate placement on prepared boards.

Questions about this item

Does the PIC18F46K42-I PT TQFP44 come with any accessories or must everything else be sourced separately?

Only the microcontroller itself is supplied; programming hardware, development boards, decoupling capacitors, crystal or resonator, and any application-specific components must be obtained separately.

The part number shows 46 and 42 — which variant should I select for my design?

PIC18F46K42 is a single fixed configuration; the digits denote the device family and feature set, so there is no alternative capacity or version to choose from.

What does the 44 in TQFP44 tell me about using this chip on a PCB?

It indicates a 44-lead thin quad flat pack, so the board must provide a matching 44-pad footprint and routing for all I/O, power, and programming connections.
