PIC18F4520-EPT LQFP44 microcontroller

The PIC18F4520-EPT is an 8-bit microcontroller in a 44-pin LQFP package. It suits engineers building embedded control boards and students learning PIC architecture. The device arrives in new condition from YINGHUA.

Replaces older PIC18F parts lacking the 4520

Designers move to this part when they need the specific peripheral mix and flash size the 4520 provides. The jump is worth it if existing code targets the PIC18 core and the pinout matches the LQFP44 footprint. It is not for buyers who need more program memory or a different package style.

Soldering the LQFP44 package needs standard

A hot-air station or reflow oven gives reliable joints; hand soldering with a fine tip works for prototypes. Common issues are solder bridges between the 44 leads and insufficient heat on the ground pad. Verify orientation before reflow to avoid rotated placement.

Questions about this item

What board footprint and pin count does the LQFP44 package require?

The LQFP44 package needs a 44-pin LQFP footprint with matching pad spacing.

Which orientation mark must align during reflow soldering of the PIC18F4520-EPT?

Align the pin-1 dot or chamfer on the IC with the pin-1 indicator on the PCB silkscreen before reflow.

How is the PIC18F4520-EPT reprogrammed after the firmware is finalised?

Reprogram the device through the ICSP interface using a compatible programmer such as a PICkit.
