Overview

The PIC18F26K42-I/SO is an 8-bit PIC18 microcontroller featuring 64KB of Flash memory and a 64MHz internal oscillator. Part of the K42 family, it integrates Core Independent Peripherals (CIPs) such as DMA and Vectored Interrupts to improve system performance while reducing CPU overhead. Its 28-pin SOIC package and 1K byte EEPROM make it suitable for space-constrained applications requiring non-volatile data storage.

Why Choose This Part

The inclusion of two Direct Memory Access (DMA) controllers and a Vectored Interrupt controller allows for high-speed data handling and deterministic response times usually found in 16-bit or 32-bit MCUs. It also features a high level of hardware integration with 1024 bytes of dedicated EEPROM and Core Independent Peripherals that function while the CPU is in Sleep mode to save power.

Applications

Industrial Sensor Nodes
Utilizing the 12-bit ADC with Computation (ADC2) and DMA to automate data acquisition from analog sensors without CPU intervention.
Communication Bridges
Implementing UART, I2C, and SPI protocols to act as a protocol converter or peripheral controller in larger embedded systems.
System Supervisory Circuits
Leveraging the Windowed Watchdog Timer (WWDT) and Brown-out Reset (BOR) to monitor system health and ensure reliable operation.
Power Management Control
Using on-chip PWM and hardware limit timers to manage power conversion or simple motor control stages.

Getting Started

Development is primarily supported through Microchip's MPLAB X IDE and the XC8 C Compiler. For rapid hardware prototyping, the Curiosity Nano or a PIC18F26K42-specific development board can be used alongside the MPLAB Code Configurator (MCC) to graphically initialize the DMA and peripheral settings. Hardware debugging is typically performed via an MPLAB PICkit 4 or MPLAB ICD 4 in-circuit debugger.
