Overview

The PIC18F27Q43-I/SP is a high-performance 8-bit microcontroller featuring 128KB of Flash memory and a sophisticated set of Core Independent Peripherals (CIPs). This part is housed in a 28-pin SPDIP package, making it an ideal choice for functional safety applications that require robust hardware-based task offloading and rapid prototyping.

Why Choose This Part

This MCU excels due to its Core Independent Peripherals which reduce CPU overhead and power consumption while increasing system reliability. The 28-pin SPDIP package is increasingly rare for high-density 128KB Flash MCUs, providing a unique path for through-hole development and easy repairability.

Applications

Industrial Safety Systems
Utilizes integrated hardware features like the Windowed Watchdog Timer (WWDT) and Cyclic Redundancy Check (CRC) with Memory Scan for functional safety compliance.
Automotive Sensor Interfacing
The 12-bit ADC with Computation (ADCC) and multiple UART/LIN interfaces handle complex analog sensor data with minimal CPU intervention.
Real-Time Control Loops
The 64MHz clock speed combined with Configurable Logic Cells (CLC) allows for high-speed hardware-based signal routing and control.
Breadboard Prototyping
The 28-pin SPDIP form factor enables engineers to prototype complex 128KB Flash applications directly on standard solderless breadboards.
