Embedded - Microcontrollers

A microcontroller, also known as a micro-control unit (MCU), is a semiconductor IC chip built with the CPU of computers and other electronic devices responsible for controlling all the ongoing operations in a CPU. In today's world, various microcontrollers are used in a wide range of electronic systems, including smartphones, computers, automobiles, and telecommunications. A microcontroller chip is a brain within the brain of an electronic system.

How Does an Embedded Microcontroller Work?

Microcontrollers can be utilized with peripherals and can be thought of as a self-contained system with processor memory, given that the bulk of microcontrollers in use today are integrated into various types of machinery, including cars, phones, appliances, and computer peripherals.

Types of Embedded - Microcontrollers:

There are several types of embedded microcontrollers, but the most common and important ones are discussed below.

8051 Microcontroller

In 1981, Intel developed the 8051 microcontrollers. An 

an 8-bit microcontroller is used. It is constructed with a 40-pin DIP (Dual inline package), 2 16-bit timers, 4 KB of ROM storage, and 128 KB of RAM storage. It comprises four parallel 8-bit ports that can be programmed and addressed by the specification.

MSP Microcontroller

Mixed Signal Processor abbreviated as MSP. It's the Texas Instruments clan. The MSP is created for low cost, and thus low power dissipation embedded statements, and is built around a 16-bit CPU. An IC chip called a microcontroller runs programs to control other machines or devices. Microcontrollers Programming refers to the programming of a micro device that is used to operate other equipment. The 16-bit data point bus, 7 attending modes, and the lesser commanding set, which enables a briefer, deeper programming code for quick performance, are all closely packed to the controller's look.

ARM Microcontroller

Advanced RISC Machine is the ARM acronym. In the field of digital embedded systems, it is the most widely used microcontroller programming. Most companies only use ARM microcontrollers since they have essential capabilities that enable the implementation of goods with a superior aesthetic. It is a high-performance, cost-sensitive device that has been employed in a variety of applications, including wireless networking and sensor systems, automobile body systems, and industrial instrument control systems.

Advantages of Embedded - Microcontrollers:

• The progress of the project can be practically seen.
• Lower prices and easy to carry due to its limited size.
• Can be embedded easily into any electronic machine
• Microcontrollers are easy to program, with no complication while programming them.
• To see the practical result, a stimulator must be used to note the progress of the operations.
  

Applications of Embedded - Microcontroller:

• Protection Alarms systems
• Vehicles
• Daily used home or office appliances 
• Digital Cameras
• Smartphones
• Electronic Equipment
• Microwave ovens
