Overview

The PIC18F26K20-I/SS is a high-performance 8-bit microcontroller featuring Microchip's eXtreme Low Power (XLP) technology and a 64KB Flash memory capacity. It operates at speeds up to 64MHz and integrates a 10-bit ADC, internal EEPROM, and versatile serial communications in a compact 28-pin SSOP package. This MCU is designed for applications where power efficiency and processing speed must be balanced.

Why Choose This Part

The XLP technology provides industry-leading low power consumption, specifically a 0.05uA sleep current, which is critical for energy-harvesting and long-term battery applications. Its C-compiler optimized architecture and extended instruction set allow for efficient code execution and high memory utilization of the 64KB Flash.

Applications

Battery-Powered Remote Sensors
Leveraging XLP technology with sleep currents as low as 0.05uA to extend battery life in wireless monitoring nodes.
Handheld Medical Devices
Utilizes the 10-bit A/D converter and low-power modes for portable diagnostic equipment requiring precise analog sampling.
Industrial Control Interfaces
Employs the 64MHz clock speed and hardware EUSART/I2C/SPI for real-time communication and control in automation systems.
Consumer Smart Appliances
Manages user interface tasks and peripheral control using its 24 I/O pins and PWM modules.
