Overview

The PIC18F25K50-I/SP is an 8-bit microcontroller featuring eXtreme Low Power (XLP) technology and an integrated Full-Speed USB 2.0 module. Operating at up to 48MHz with 32KB of Flash memory, it includes a high-precision internal oscillator that eliminates the need for external crystals in USB applications. This specific variant comes in a 28-pin SPDIP package, making it ideal for prototyping and through-hole assembly.

Why Choose This Part

The primary advantage is the crystal-less USB operation, which reduces BOM cost and board space by using the internal clock recovery system. It provides a robust 5V-tolerant I/O system and 25mA source/sink capability, simplifying the interface to legacy industrial hardware and LEDs. The 28-pin PDIP package is specifically advantageous for breadboarding and educational environments where surface-mount soldering is not preferred.

Applications

USB Peripheral Devices
Utilizing the integrated USB 2.0 interface for PC human interface devices (HID), custom data loggers, or communication bridges.
Battery-Powered Instrumentation
Taking advantage of XLP technology and 0.02uA sleep currents for long-term operation in portable sensing equipment.
Industrial Control Interfaces
Implementing RS-232 or RS-485 to USB conversion using the onboard UART and USB modules.

Getting Started

Develop firmware using Microchip MPLAB X IDE and the XC8 compiler, leveraging the MPLAB Code Configurator (MCC) to initialize the USB stack and peripherals. Hardware debugging and programming require a tool such as the PICkit 4 or MPLAB ICD 4 connected via the ICSP pins. For rapid prototyping, the chip can be placed directly into a standard breadboard or a 28-pin DIP socket.
