PIC18F24K22-I/SO microcontroller for embedded

The PIC18F24K22-I/SO is an 8-bit microcontroller in a 28-pin SOP package. It suits engineers building control boards, sensor interfaces or low-power embedded systems. The device delivers the core PIC18 architecture with integrated peripherals for straightforward firmware development.

24 KB flash and 28 pins define capacity

The 24 KB program memory handles modest firmware images but leaves no headroom for large libraries or graphical assets. Twenty-eight pins restrict simultaneous I/O, so designs needing many external buses or high-pin-count displays will require a larger package or additional logic.

Questions about this item

Will the 28-pin SOP package fit the existing footprint on my older PIC18 board?

The device uses a standard SOP-28 package with the same pin pitch and body width as legacy PIC18F parts, so it drops into the existing footprint without layout changes.

How can I confirm the PIC18F24K22 is running after I solder it?

Apply power, then use a PICkit or ICD programmer to read the device ID register; a valid response of 0x18 0x22 0x24 confirms the chip is alive and communicating.
