MCHPPIC18F26K42-E/SO
Overview
The PIC18F26K42-E/SO is a high-performance 8-bit microcontroller featuring 64KB of Flash memory and a rich set of Core Independent Peripherals (CIPs) designed for hardware-based task offloading. It operates at up to 64MHz and includes a 12-bit ADC with computation features (ADC2) and Direct Memory Access (DMA) to minimize CPU intervention in data movement. This specific extended temperature variant is housed in a 28-pin SOIC package, making it suitable for robust industrial environments.
Why Choose This Part
The inclusion of DMA and Vectored Interrupts significantly improves execution efficiency compared to traditional 8-bit MCUs by reducing interrupt latency and software overhead. Its Core Independent Peripherals allow for complex logic and timing functions to run autonomously, while the 5V-tolerant I/O and high drive current capability simplify interfacing with legacy industrial logic.
Applications
Getting Started
Development is supported by the MPLAB X IDE and the XC8 compiler, with the MPLAB Code Configurator (MCC) available for rapid peripheral initialization. For hardware evaluation, the Curiosity High Pin Count (HPC) Development Board or the PIC18F26K42 Curiosity Nano can be used alongside an MPLAB PICkit 4 or ICD 4 debugger.
