Microcontroller with 44-pin TQFP package

The YINGHUA PIC18F55K42-I PT is an 8-bit microcontroller supplied in a 44-pin TQFP package. It targets engineers building embedded control systems that need on-chip peripherals and flash memory. The device suits new designs as well as maintenance of existing boards that specify this part number.

Developers needing 44-pin footprint

This part suits developers who require the exact 44-pin TQFP footprint and the peripheral set defined for the PIC18F55K42-I PT. It does not suit projects that need a different pin count, a different package style, or a higher core clock than this device provides. Buyers who want more I/O pins or a larger flash array should look at other devices.

Fixed 44-pin TQFP footprint

The decisive specification is the 44-pin TQFP package, which fixes the board layout and soldering process. If the PCB land pattern or the pick-and-place data call for this exact footprint, the part fits; otherwise a different package must be chosen.
