Overview

The PIC18F47K42-E/PT is an 8-bit PIC18 microcontroller featuring 128KB of Flash memory and a 64MHz clock speed, designed for high-performance embedded control. It integrates advanced Core Independent Peripherals (CIPs) and Vectored Interrupts to reduce CPU overhead and improve real-time response. This part includes dual DMA controllers and a Windowed Watchdog Timer for enhanced system reliability in industrial environments.

Why Choose This Part

This MCU offers a massive 128KB Flash capacity for an 8-bit architecture, allowing for extensive firmware features. The inclusion of Core Independent Peripherals and DMA enables high throughput and reduced power consumption by offloading tasks from the CPU. It supports a wide operating voltage up to 5.5V, making it highly resilient to noise in industrial power environments.

Applications

Industrial Automation
Utilizing the dual DMA controllers and hardware CRC to manage complex sensor data and communication without interrupting the main CPU.
Real-Time Control Systems
Leveraging the Vectored Interrupt controller for fast, deterministic response times in time-critical control loops.
Human-Machine Interface (HMI)
Managing small displays and touch inputs using the 36 available I/O pins and integrated PWM peripherals.
Power Management
Implementing supervisory tasks using the Low-Power Brown-out Reset and 1K bytes of EEPROM for non-volatile parameter storage.
