MCHPPIC18F26K42-I/SP
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
Key Specifications
Getting Started
Development is supported by the MPLAB X IDE and the XC8 C compiler. For hardware debugging and programming, use the MPLAB PICkit 4 or Snap in-circuit debugger connected to the ICSP pins.
