PIC18F4423-I PT microcontroller

The YINGHUA PIC18F4423-I PT is a new semiconductor device classified as an integrated circuit. It serves engineers and developers building embedded control applications. This component provides the core processing logic for custom electronic designs. Buyers needing a different architecture or higher pin count must select another part.

Fits custom PCB layouts

Integration requires a printed circuit board designed for the specific package footprint and voltage requirements. The device frees up board space by combining processor, memory, and peripherals in a single package. Surrounding circuitry must supply regulated power and any necessary oscillator components. Builders without PCB fabrication capability cannot use this bare die.

No bundled accessories included

The component ships as a standalone integrated circuit without sockets, programmers, or development boards. Users must source programming hardware and software toolchains separately. This absence means immediate prototyping requires additional investment in support equipment. The lack of included firmware libraries shifts all software development to the engineering team.

Questions about this item

How much flash memory does the PIC18F4423-I PT provide for program storage?

The PIC18F4423-I PT includes 18 KB of on-chip flash program memory for firmware storage.

What is the typical power dissipation when the device runs continuously at 5 V?

At 5 V supply the PIC18F4423-I PT draws only a few milliamps in active mode, so heat rise is minimal without a heatsink.

Which programmer hardware is needed to load code onto the PIC18F4423-I PT?

An ICSP-compatible programmer such as a PICkit or MPLAB ICD connects to the PGD and PGC pins for in-circuit programming.
