Overview

The PIC18F26K83-I/SO is an 8-bit microcontroller designed for robust industrial and automotive applications requiring functional safety and integrated CAN communication. It features 64KB of Flash memory, Core Independent Peripherals (CIPs), and Vectored Interrupts to reduce CPU overhead in real-time control tasks. This member of the PIC18-K83 family includes two DMA controllers and a System Bus Arbiter to manage high-speed data movement without processor intervention.

Why Choose This Part

This MCU excels in deterministic performance due to its Vectored Interrupt controller and dual DMA channels that minimize interrupt latency. It includes 1KB of dedicated EEPROM for persistent parameter storage and is built on XLP technology for extremely low power consumption, reaching shutdown currents as low as 0.07uA. The functional safety (FuSa) features provide hardware-level reliability for mission-critical applications.

Applications

Automotive CAN Node
Utilizes the integrated CANbus controller for reliable vehicle networking in body electronics or powertrain modules.
Industrial Safety Systems
Leverages functional safety features like the Windowed Watchdog Timer (WWDT) and Memory Access Partitioning (MAP) to meet safety standards.
Complex Sensor Fusion
Uses the 12-bit ADC with computation and DMA to process multiple analog inputs while the core handles communication tasks.
Smart Lighting Control
Applies the on-chip PWM and Configurable Logic Cells (CLC) to create hardware-based lighting effects and power conversion.

Getting Started

To begin development, use the MPLAB X IDE and the XC8 C Compiler provided by Microchip. The Curiosity High Pin Count (HPC) Development Board (DM164136) is a suitable hardware platform for prototyping this 28-pin device. You can use the MPLAB Code Configurator (MCC) to graphically initialize the CAN, DMA, and other Core Independent Peripherals.
