Overview

The PIC18F27K40-I/SO is a high-performance 8-bit microcontroller featuring 128KB of Flash memory and 3.6KB of RAM in a 28-pin SOIC package. Part of the PIC18 K40 family, it integrates eXtreme Low-Power (XLP) technology with Core Independent Peripherals (CIPs) to handle complex timing and control tasks with minimal CPU intervention. Operating at speeds up to 64MHz, it includes 1024 bytes of EEPROM and a 10-bit ADC with Hardware Capacitive Voltage Divider (CVD) support.

Why Choose This Part

This MCU offers a high memory density for an 8-bit device, providing 128KB of Flash for complex firmware routines. The Peripheral Pin Select (PPS) feature allows flexible I/O mapping to simplify PCB routing, while Core Independent Peripherals reduce power consumption by offloading tasks from the CPU core.

Applications

Touch-Sensing Interfaces
Utilizes the built-in Hardware Capacitive Voltage Divider (CVD) to implement robust touch buttons and sliders with reduced software overhead.
Industrial Control Systems
Leverages the Zero-Cross Detect (ZCD) and Complementary Waveform Generator (CWG) for efficient power switching and motor control applications.
Battery-Powered IoT Nodes
Employs XLP technology and various low-power modes (Sleep, Idle, Doze) to extend battery life in remote monitoring applications.
