PIC18F4520-I PT TQFP44 microcontroller

The PIC18F4520-I PT TQFP44 is an 8-bit microcontroller in a 44-pin thin quad flat pack. It suits engineers developing embedded control applications for industrial or consumer equipment. The device provides on-chip program memory and peripherals for real-time tasks. Buyers receive a new component ready for prototype or production use.

Verify voltage logic levels and pin assignment

Confirm the target board operates at the voltage range required by this 44-pin package before ordering. Check the printed circuit board footprint matches the TQFP44 pitch and pad layout. Ensure the programmer or debugger header aligns with the ICSP pins on the device. Review the oscillator configuration options against the clock source on your design.

Stable operation during continuous duty

The part maintains consistent timing and peripheral response during extended run cycles typical of embedded firmware. Thermal performance stays within specification when the package is soldered to a correctly designed copper pour. Code execution remains deterministic without unexpected resets under sustained interrupt loads. Long-term reliability is supported by the mature silicon process used for this device.

Questions about this item

What is included with the PIC18F4520-I PT TQFP44 IC and what must be sourced separately?

The device itself is supplied new in a 44-pin TQFP package; a printed circuit board, decoupling capacitors, a crystal or resonator, programming header and power supply are not included and must be obtained separately.

How do I choose between the different package or temperature variants of the PIC18F4520?

The part code shown is the industrial-temperature TQFP44 version; if your design needs a different package such as DIP or QFN, or the extended temperature range, you will need to order the corresponding part number instead.

What does the 18 in the part name mean for code density and interrupt latency in a finished board?

The 18 indicates the PIC18 enhanced 8-bit core, which provides a hardware multiplier, priority interrupt levels and a 21-bit program counter that together reduce interrupt latency and improve code density compared with baseline PIC families.
