Overview

The PIC18F26K40-I/SP is an 8-bit microcontroller that combines 64KB of Flash memory with Core Independent Peripherals (CIPs) for high-performance, low-power applications. Operating at up to 64MHz, it features 1KB of EEPROM and integrated hardware such as a Zero-Cross Detect (ZCD) and Windowed Watchdog Timer (WWDT). The 28-pin SPDIP package makes it particularly well-suited for through-hole prototyping and legacy system maintenance.

Why Choose This Part

This MCU offers a high memory-to-pin ratio with 64KB of Flash in a compact 28-pin footprint. Its eXtreme Low-Power features, such as Doze and Idle modes, allow for granular power management, while the 5.5V maximum VDD provides excellent noise immunity for industrial designs.

Applications

Industrial Sensor Nodes
Utilizes the 10-bit ADC with Hardware CVD and Fixed Voltage Reference for precise analog data collection in harsh environments.
Power Control Systems
The Zero-Cross Detect and PWM modules enable efficient AC load switching and motor control timing.
Low-Power Handheld Devices
Employs eXtreme Low-Power (XLP) technology and Peripheral Module Disable (PMD) to minimize current draw in battery-operated equipment.
Breadboard Prototyping
The 28-pin SPDIP form factor allows engineers to quickly validate 8-bit logic and peripheral configurations without custom PCBs.

Getting Started

Develop firmware using the MPLAB X IDE and the XC8 Compiler. Hardware programming and debugging are typically performed using the MPLAB PICkit 4 or MPLAB Snap via the ICSP interface. For rapid prototyping, the MPLAB Code Configurator (MCC) can be used to generate peripheral initialization code.
