Overview

The PIC18F14K22-I/SO is a high-performance 8-bit microcontroller from Microchip's XLP (eXtreme Low Power) family, designed for power-sensitive applications. It operates at speeds up to 64MHz and features 16KB of Flash memory along with a dedicated 256-byte EEPROM for non-volatile data storage. This device integrates a variety of digital and analog peripherals, including a hardware 8x8 multiplier and multiple serial communication interfaces in a 20-pin SOIC package.

Why Choose This Part

This MCU offers a compelling balance of speed and efficiency with a 64MHz clock and a single-cycle hardware multiplier. Its precision 16MHz internal oscillator block reduces component count, while the self-reprogrammable Flash under software control allows for flexible field updates.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology for extended battery life in wireless monitoring nodes.
Handheld Portable Devices
Small footprint and low power consumption make it ideal for portable consumer electronics.
Industrial Control Logic
Integrated LINbus support and robust peripheral set for localized industrial automation tasks.
System Supervisory Controllers
Manages power sequencing and system monitoring using POR, BOR, and WDT peripherals.

Getting Started

To begin development, use the MPLAB X IDE and the XC8 C Compiler. Hardware debugging and programming are supported via the PICkit 4 or MPLAB ICD 4 using the In-Circuit Serial Programming (ICSP) interface. Evaluation can be performed using the Low Pin Count USB Development Kit or by prototyping on a breadboard with the SOIC-to-DIP adapter.
