Microcontroller in 44-pin TQFP package

The PIC18F45Q43-I PT is a microcontroller supplied in a 44-pin TQFP package. It is intended for engineers and developers designing embedded control systems. The part is new and was first listed by the manufacturer in 2025. This device suits applications requiring an 8-bit core with integrated peripherals.

Operating voltage and temperature constraints

The device operates within the standard voltage and temperature limits defined for the PIC18F family. Designs must respect the absolute maximum ratings for supply voltage and I/O pins. Exceeding these limits can cause permanent damage. Thermal performance depends on the PCB layout and the 44-pin TQFP package characteristics.

Verify toolchain and footprint compatibility

Confirm that your compiler and debugger support this specific part number before ordering. The 44-pin TQFP footprint must match your PCB design rules. Buyers who need a different pin count or package style should select an alternative device. Ensure the development environment includes the correct device header files.
