YINGHUA PIC18F6586-I PT LQFP44 semiconductor

PIC18F6586-I PT LQFP44 microcontroller

The PIC18F6586-I PT LQFP44 is an 8-bit microcontroller from Microchip Technology, supplied by YINGHUA as new-old-stock semiconductors. It targets engineers maintaining legacy industrial boards or students learning PIC18 architecture on existing PCB layouts that specify this exact part.

Verify LQFP44 footprint

Confirm your board uses the 44-pin LQFP package and that your toolchain supports the PIC18F6586 core, because the device is not pin-compatible with other PIC18 families and requires a 5 V programming environment. Buyers who need a different pin count, lower-voltage operation or modern debugging interfaces cannot use this component.

Tray packaging suits manual placement

Devices arrive in standard JEDEC trays rather than tape-and-reel, which simplifies hand soldering or small-batch pick-and-place without a feeder investment. No development board, programmer or software licence is bundled, so you must source those separately.
