Overview

The PIC18F26K42-I/SP is a high-performance 8-bit microcontroller featuring 64KB of Flash and Core Independent Peripherals (CIPs) that offload tasks from the CPU for increased efficiency. It is housed in a 28-pin SPDIP package, making it an ideal choice for through-hole prototyping and legacy system integration requiring advanced 8-bit processing.

Why Choose This Part

The integration of Direct Memory Access (DMA) and Vectored Interrupts significantly reduces CPU overhead compared to standard 8-bit MCUs. Its 28-DIP form factor allows for easy breadboarding and socketed replacement in industrial hardware.

Applications

Industrial Control Systems
Utilizes the Windowed Watchdog Timer (WWDT) and Brown-out Reset (BOR) for reliable operation in electrically noisy environments.
Sensor Interfacing
Features a 12-bit ADC with Computation (ADC2) and Zero-Cross Detect (ZCD) for precise analog signal processing.
Automotive Networking
Includes hardware support for LINbus and UART/USART, suitable for localized vehicle control modules.
