Overview

The PIC18F26K22-I/SO is a high-performance 8-bit microcontroller from Microchip Technology featuring eXtreme Low-Power (XLP) technology for battery-sensitive applications. It operates at up to 64MHz and includes 64KB of Flash memory, 1KB of EEPROM, and a comprehensive set of analog and digital peripherals in a 28-pin SOIC package.

Why Choose This Part

This MCU offers a high memory-to-pin ratio with 64KB of Flash in a compact 28-pin footprint while maintaining 5V compatibility. The XLP technology provides industry-leading low-power currents, such as 10uA in sleep mode, making it ideal for energy-harvesting and long-term battery use.

Applications

Industrial Sensor Nodes
Utilizes the integrated 10-bit ADC with auto-acquisition and low-power sleep modes for remote monitoring applications.
Capacitive Touch Interfaces
Leverages the Charge Time Measurement Unit (CTMU) for implementing robust touch buttons and sliders without external controllers.
Battery-Powered Handhelds
Takes advantage of XLP features and a wide 2.3V to 5.5V operating range to maximize life from lithium or alkaline cells.
Legacy Logic Replacement
The 5V tolerant I/O and large Flash capacity allow for replacing complex discrete logic or older 8-bit MCUs in existing industrial designs.
