Overview

The PIC18F26K83-I/SP is a high-performance 8-bit microcontroller featuring 64KB of Flash and 4KB of RAM, designed for functional safety and robust communication. It integrates specialized peripherals like a CAN bus controller, DMA, and vectored interrupts to handle complex tasks with minimal CPU intervention. Housed in a 28-pin SPDIP package, it is particularly suited for through-hole prototyping and industrial environments.

Why Choose This Part

This MCU offers independent peripheral operation through two DMA controllers and a vectored interrupt controller, significantly reducing software overhead. It provides a robust communication suite including CAN, I2C, and UART, along with XLP technology for ultra-low power consumption as low as 0.07uA in sleep mode.

Applications

Automotive Networking
Utilizes the integrated CANbus and LINbus support for vehicle diagnostics and sensor modules.
Industrial Safety Systems
Leverages functional safety (FuSa) features and the Windowed Watchdog Timer (WWDT) for mission-critical monitoring.
Robotic Control
Uses DMA and the system bus arbiter to manage multiple sensors and motor control PWM outputs simultaneously.
Data Logging
Takes advantage of 1KB of EEPROM and 16-bit CRC with scanner for reliable non-volatile storage and data integrity checks.

Getting Started

Begin development using the MPLAB X IDE and the XC8 C Compiler. For hardware evaluation, the Curiosity High Pin Count (HPC) Development Board is recommended, and the chip can be programmed via the MPLAB PICkit 4 or ICD 4 in-circuit debugger. The 28-pin SPDIP package allows for direct placement on standard breadboards for rapid prototyping.
