MCHPPIC18F25K50-I/SO
Overview
The PIC18F25K50-I/SO is a high-performance 8-bit microcontroller featuring eXtreme Low Power (XLP) technology and integrated Full-Speed USB 2.0. Operating at up to 48MHz, it includes 32KB of Flash memory and a specialized Charge Time Measurement Unit (CTMU) for advanced sensing applications.
Why Choose This Part
This MCU offers a crystal-less USB operation mode which reduces BOM cost and PCB footprint. Its CTMU peripheral provides a hardware-based solution for capacitive touch and precision time measurement that offloads the CPU, while the XLP architecture ensures industry-leading power consumption in standby modes.
Applications
Key Specifications
Getting Started
Develop applications using Microchip's MPLAB X IDE and the XC8 C Compiler. For hardware evaluation, the MPLAB PICkit 4 or MPLAB Snap debugger can be used to program the device via its ICSP interface. Detailed USB stack examples are available through the Microchip Libraries for Applications (MLA).
