PIC18F25K80 8-bit MCU for embedded control

The PIC18F25K80 is an 8-bit microcontroller in a 28-pin SOIC package designed for general embedded applications. It provides 18 KB of program memory and integrated peripherals for real-time control tasks. Engineers building new boards can solder this device directly for compact designs. It is not suited for buyers who need a larger pin count or higher core performance.

Low-power operation in SOIC-28 package

The device runs on a low-voltage supply and draws minimal current during active and sleep modes. Thermal output remains negligible in typical enclosed environments without forced airflow. No heatsink or active cooling is required for normal operation. Power consumption scales with clock frequency and peripheral usage.

Questions about this item

How do I solder the SOIC-28 package without bridging pins?

Use a fine-tip iron, apply flux to all 28 pins, tack the two corner pins first to align the chip, then drag-solder each row; inspect with a loupe for bridges before powering the 8-bit MCU.

What long-term wear should I plan for on the PIC18F25K80?

The 18-series Flash and EEPROM have finite erase-write endurance; design firmware to minimise unnecessary writes and include a wear-levelling strategy for data that changes often.
