Microcontroller for embedded development

The YINGHUA PIC18F56K42-I PT is an 8-bit microcontroller supplied in a 44-pin TQFP package. It integrates core independent peripherals and flash memory for deterministic real-time control. Engineers select this device when a compact footprint and low pin count match the board layout.

Suits space-constrained designs.

This part fits projects that require 44 pins or fewer and benefit from the enhanced PIC18 instruction set. Builders who need more I/O lines, larger program memory, or a different package style should look at alternative devices that provide those resources.

44-pin TQFP package defines board compatibility

The 44-lead thin quad flat pack sets the exact land pattern and routing clearance for the printed circuit board. Verify that the schematic and layout match this footprint before committing to production.

Questions about this item

What board layout fits the 44-pin TQFP package of the PIC18F56K42-I PT?

The PIC18F56K42-I PT uses a 44-pin TQFP package; design the footprint to match the 44-lead outline and pad dimensions from the manufacturer datasheet.

What soldering profile suits the TQFP44 package during assembly?

Follow the standard lead-free reflow profile for TQFP44 ICs; the critical step many miss is exceeding the peak temperature or dwell time, which can damage the die.

When should the PIC18F56K42-I PT be replaced in a long-running design?

Replace the device if it fails self-test, shows erratic I/O behavior, or after the manufacturer's rated endurance cycles for flash and EEPROM are exceeded.
