PIC18F46K42-E PT TQFP44 Microcontroller

The PIC18F46K42-E PT TQFP44 is a new 8-bit microcontroller supplied by YINGHUA for embedded electronic designs. It integrates core processing, memory and peripherals in a single 44-pin TQFP package ready for surface-mount assembly. This semiconductor suits engineers developing control firmware for industrial or consumer equipment. Its IC construction supports direct PCB integration without additional carrier hardware.

For Embedded Firmware Engineers Not For High Pin

This device suits developers writing C or assembly firmware for standalone control tasks using the PIC18 architecture. It fits projects needing 44 pins in a thin quad flat pack for compact board layouts. Buyers who need more I/O lines or a larger package footprint should look at alternative microcontrollers with higher pin counts. The fixed 44-lead format limits expansion on space-constrained boards requiring extra connectivity.

44-Pin TQFP Package Defines Board Compatibility

The 44-pin TQFP package is the single specification that decides whether this part fits the target PCB land pattern. Lead pitch and body dimensions follow the standard TQFP44 outline for automated reflow soldering. Verify the board footprint matches this exact package before ordering to avoid assembly mismatches. No other package variant is offered under this part number.

Questions about this item

What PCB footprint do I need so the 44-pin TQFP package solders correctly?

The device uses a 44-lead TQFP package; design the board with a matching 44-pin TQFP footprint and follow the manufacturer's land-pattern dimensions.

Will the 18F core run code written for earlier 8-bit PIC parts I still have?

The PIC18F46K42-E PT is an 18F-series microcontroller; existing 8-bit PIC source must be recompiled for the 18F instruction set and register map.

How do I confirm the chip is executing after I program it?

Toggle a GPIO pin in firmware and probe it with an oscilloscope or LED; successful toggling shows the 46K42 core is running.
