Overview

The PIC18F27Q43-E/SS is an 8-bit microcontroller from the PIC18-Q43 family, featuring 128KB of Flash and Core Independent Peripherals (CIPs) designed for hardware-based control. This specific variant is rated for extended temperatures (-40C to +125C) and includes integrated functional safety features to simplify ISO 26262 and IEC 61508 compliance. It is optimized for robust real-time control applications where high memory density and low power consumption are required.

Why Choose This Part

The Q43 series excels by offloading timing-critical tasks to hardware via Core Independent Peripherals, reducing CPU overhead and power consumption. With 128KB of Flash and 1KB of EEPROM, it provides significant headroom for high-level language code in an 8-bit architecture. Its functional safety hardware helps designers meet rigorous reliability standards with minimal software complexity.

Applications

Automotive Body Control
Utilizes the AEC-Q100 qualification and extended temperature range for lighting control and window lift systems.
Industrial Safety Controllers
Leverages hardware-based functional safety features like the CRC with memory scan and Windowed Watchdog Timer (WWDT).
Sensor Fusion Hub
The 128KB Flash and 8KB RAM accommodate complex algorithms for processing multiple analog and digital sensor inputs.
Distributed Control Systems
Uses multiple UART, SPI, and I2C interfaces for communicating across industrial networks and local subsystems.

Getting Started

Developers can begin by using the MPLAB X IDE and the XC8 compiler provided by Microchip. The Curiosity Nano evaluation board (MPN: EV26Q64A) offers a rapid prototyping platform with full programmer/debugger integration. Microchip's Code Configurator (MCC) is highly recommended for initializing the Core Independent Peripherals through a graphical interface.
