Overview

The PIC18F26K42-E/SS is an 8-bit microcontroller from Microchip's PIC18 K42 family, featuring 64KB of Flash and a Core Independent Peripheral (CIP) architecture. It operates at up to 64MHz and includes a Direct Memory Access (DMA) controller and Vectored Interrupts (VI) to improve system performance by offloading tasks from the CPU. This specific variant is rated for extended temperature ranges and comes in a compact 28-pin SSOP package.

Why Choose This Part

This MCU excels in deterministic performance due to its Vectored Interrupt controller which minimizes latency. The inclusion of 1024 bytes of dedicated EEPROM and 4K of RAM provides ample space for local data logging and complex state machines. Its Core Independent Peripherals allow for high-speed signal processing and control while maintaining low power consumption.

Applications

Automotive Sensor Interface
Utilizes the integrated LINbus support and 12-bit ADC with Computation (ADC2) for processing analog sensor data in vehicle subsystems.
Industrial Control Systems
Employs the Windowed Watchdog Timer (WWDT) and hardware CRC/SCAN for safety-critical monitoring and high-reliability logic control.
Battery-Powered IoT Nodes
Leverages XLP technology with a 0.8uA sleep current and Doze/Idle modes to extend battery life in remote sensing applications.
Power Management Controllers
Uses on-chip PWM and DMA to manage power conversion and monitoring without heavy CPU intervention.

Getting Started

To begin development, use the Microchip MPLAB X IDE and the XC8 C Compiler. Hardware debugging is best supported via the MPLAB PICkit 4 or ICD 4 in-circuit debuggers. For rapid prototyping, the Curiosity Nano or Explorer 8 development boards can be used to interface with the 28-pin SSOP via an adapter or custom PCB.
