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

Industrial Sensor Nodes
Utilizing the 12-bit ADC2 and internal temperature sensor for local signal processing and environmental monitoring.
System Supervisory Circuits
Using the Windowed Watchdog Timer (WWDT) and Zero-Cross Detect (ZCD) to monitor power rails and AC line conditions.
Hardware-Based Control Loops
Leveraging Complementary Waveform Generators (CWG) and Configurable Logic Cells (CLC) for high-speed power or motor control.
Data Logging and Buffering
Exploiting the 4KB of RAM and 1KB of dedicated EEPROM for non-volatile storage of configuration and calibration data.

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.
