A Microcontroller is a small integrated circuit device that governs the electronic operations in the embedded systems. It is a self-contained microcomputer that encompasses the functions of CPU, memory, peripherals, or input/output interfaces on one chip. This controller unit can execute highly specific automated functions in a single device preprogrammed by the user.
For example, they play significant roles in vending machines, home supplies, medical equipment, robotics, office machines, and vehicles. These personal computers are usually tailored to gather input and show the action taken after processing the required information. They control the compact features of the larger component without using a front-end operating system.
Moreover, these embedded Microcontrollers are designed to operate at lower speeds and consume less power due to CMOS technology. With less cost in design and hardware, they’re an economical choice for electronic enthusiasts.
Elements of Microcontroller
The core elements of the Microcontroller consist of the following:
Central Processing Unit
CPU is considered to be the brain of a microcontroller. It executes basic arithmetic, I/O operations, and logical functions. This element is indispensable in communicating commands to other components by executing data transfer operations in larger embedded systems.
Memory
This part of the microcontroller holds the data and program code the processor receives and deploys to respond to particular instructions. To perform its role efficiently, it consists of volatile and non-volatile storage types.
Input/Output Ports
These are the connective pins that the Microcontroller unit (MCU) employs to connect to the other circuits. They allow for the flow of information and input/output data signals to perform a particular action.
Peripherals
These are the additional components that make the Microcontroller adaptable for diverse applications. For example, timers, serial ports, converters, communication modules, or internal oscillators may be involved in this category. They enhance the Microcontroller’s capabilities and help in their functionality.
What does a Microcontroller do?
Microcontrollers use the central processing unit to interact with the outside world through I/O ports. They are programmed with specific C, C++, or assembly language instructions. The program logic defines how the Microcontroller responds to different inputs, processes information, and produces desired outputs.
The embedded microcontrollers interpret the received information by storing temporary data in RAM. The processor accesses this information and deploys the data in program memory to apply a particular function.
Types of Microcontroller Units
Various microcontrollers are specially designed for particular applications. This subdivision is based on the bus width, memory, instruction set architecture, and more. Let’s discuss some of the main types of microcontroller units (MCUs).
