Overview

The PIC18F25K50-I/ML is an 8-bit microcontroller featuring eXtreme Low Power (XLP) technology and an integrated USB 2.0 Full Speed interface. It operates at up to 48MHz and includes a high-precision internal oscillator that enables USB communication without an external crystal. With 32KB of Flash memory and 2KB of RAM, it is designed for power-sensitive applications that require a direct PC interface.

Why Choose This Part

The primary advantage is the crystal-less USB operation, which reduces PCB footprint and total Bill of Materials cost. It also offers wide operating voltage from 2.3V to 5.5V and robust 5V-tolerant I/O, making it versatile for both legacy and modern digital logic levels. High-current I/O pins capable of sinking or sourcing 25mA simplify driving LEDs or small relays directly.

Applications

USB Peripheral Devices
Ideal for creating crystal-less USB HID devices, such as custom keyboards, mice, or industrial joysticks.
Battery-Powered Instrumentation
Utilizes XLP technology with sleep currents as low as 20nA to extend the life of handheld measurement tools.
Portable Data Loggers
Combines 256 bytes of EEPROM for configuration storage with a 10-bit ADC for sensor data collection.
USB-to-Serial Converters
Implements the UART and USB interfaces to bridge legacy serial hardware to modern computing environments.

Getting Started

Development is supported by the MPLAB X IDE and the XC8 compiler. For hardware prototyping, the MPLAB PICkit 4 or MPLAB Snap in-circuit debugger/programmers are standard choices for the 28-QFN package. Microchip's Code Configurator (MCC) can be used to quickly initialize the USB stack and peripheral drivers.
