Overview

The PIC18F27Q43-E/SO is a high-performance 8-bit microcontroller featuring Core Independent Peripherals (CIPs) and hardware-based functional safety features. Operating at up to 64MHz with 128KB of Flash memory, it is designed for real-time control applications that require high reliability and minimal CPU intervention. This variant is rated for extended temperature ranges, making it suitable for demanding automotive and industrial environments.

Why Choose This Part

The integration of Core Independent Peripherals allows for complex tasks like signal measurement and timing to be handled without taxing the CPU, increasing overall system efficiency. It includes a 1K x 8 EEPROM for robust non-volatile data storage and specialized hardware features like the Signal Measurement Timer (SMT) for high-resolution timing analysis.

Applications

Automotive Body Electronics
Used in lighting control, window lift systems, and sensor interfacing where AEC-Q100 compliance and functional safety are required.
Industrial Safety Controllers
Implements hardware CRC, Windowed Watchdog Timer (WWDT), and Memory Access Partitioning (MAP) for safety-critical monitoring.
Intelligent Sensor Nodes
Utilizes the 12-bit ADC with Computation (ADC2) and Vectored Interrupts to process complex analog signals with low latency.
