PIC18F252-I/SO 28-pin SOP microcontroller

The PIC18F252-I/SO is an 8-bit microcontroller in a 28-pin SOP package for embedded control projects. It suits engineers, students and hobbyists building custom boards that need on-chip Flash and peripherals in a surface-mount footprint.

Replaces older DIP or smaller-pin-count PICs

Moving from a through-hole DIP version or a lower-pin-count device is worthwhile when a project demands the 28-pin SOP layout and the integrated feature set of this part. The jump makes sense for new PCB designs that require surface-mount assembly and the specific I/O count this package provides.

Verify voltage, programmer and footprint match

Confirm the target board runs at the voltage range your design requires and that your programmer supports this device. Check the PCB footprint against the SOP-28 land pattern and ensure the toolchain includes the correct header files for the PIC18F252 core.

Questions about this item

What PCB footprint does the SOP-28 package need?

The device uses a 28-pin small-outline package; match the board layout to the 28-lead SOP pattern shown in the manufacturer datasheet.

What is the correct orientation for soldering the IC?

Align the pin-1 marker on the package with the pin-1 pad on the board; reversing the part will prevent the PIC18F252 from functioning.

When should the microcontroller be replaced?

Replace the PIC18F252-I/SO if it fails to program, shows erratic I/O behavior, or suffers physical damage during board rework.
