In embedded hardware design, system stability depends heavily on how sensing, processing, and output control are synchronized. When these functions are split across multiple ICs, signal delay increases, debugging becomes harder, and power consumption often rises. Many embedded systems need a compact controller that can continuously read inputs, process logic, and update outputs in a predictable cycle. A Microcontroller Unit (MCU) solves this by integrating processing, memory, and peripheral control into one device built for embedded control systems.
