MCU, short for micro controller unit, is often considered synonymous with a microprocessor. It is a crucial component in computers, including elements like MCU, memory, graphics, HDD drives, and input/output devices such as Ethernet communication interfaces.
The primary function of an MCU is to read and execute instructions stored in memory. It plays a vital role in the processing and operational control of computers and various electronic devices.
MCUs are integral to computers ranging from supercomputers to consumer devices like smartphones and tablets. They are also prevalent in consumer electronics (such as TVs and audio equipment), vehicles, and professional measuring instruments. By incorporating peripheral hardware, MCUs enable device miniaturization and specialization for specific applications.
MCUs are designed to sequentially read instructions from memory, decode, and execute them, performing arithmetic operations and interfacing with peripheral devices. The set of instructions within the MCU defines its capabilities and the actions to be taken for each instruction.
Advancements in semiconductor technology have allowed MCUs to integrate functions like memory, graphics, and interfaces, contributing to device miniaturization. Integrated graphics enable data display on connected displays, while built-in Ethernet communication functions allow network data processing.
While MCUs and MPUs (Micro Processor Units) share similarities, they differ in key aspects:
MCUs, being more limited in functionality and lower in performance compared to MPUs, are chosen for their low power consumption and cost-effectiveness, particularly when their capabilities are sufficient for the desired function.
