Overview

The PIC18F26K40-I/SS is a high-performance 8-bit microcontroller featuring 64KB of Flash memory and 3.6KB of RAM in a compact 28-SSOP package. Operating at up to 64MHz, it integrates Microchip eXtreme Low-Power (XLP) technology and a robust set of Core Independent Peripherals (CIPs) to handle timing and signal conditioning tasks with minimal CPU intervention.

Why Choose This Part

This MCU offers a high degree of flexibility through Peripheral Pin Select (PPS), allowing developers to map digital peripherals to any I/O pin. Its Core Independent Peripherals reduce power consumption and software overhead by offloading routine tasks from the CPU, while the 1KB of on-chip EEPROM provides reliable non-volatile storage for calibration data.

Applications

Battery-Powered Remote Sensors
Utilizes XLP technology and a 0.6uA sleep current to extend the operating life of IoT edge nodes and environmental monitors.
Touch-Sensitive Interfaces
Leverages the hardware Capacitive Voltage Divider (CVD) support for reliable capacitive touch sensing in consumer and industrial panels.
Industrial Signal Conditioning
Uses the Zero-Cross Detect (ZCD), Fixed Voltage Reference (FVR), and 8-bit hardware acquisition timer for precise AC power control and analog sensor interfacing.
Automotive Interior Control
Integrates EUSART and LINbus compatibility for vehicle cabin functions like lighting control and window automation.
