What is Difference Between Microprocessor and Microcontroller

“How can you tell the difference between a microprocessor and a microcontroller?” It’s a basic electronics question, yet many still mistake those chemicals for the same thing.

What is a Microcontroller?

A microcontroller is a little computer built onto a single semiconductor IC (integrated circuit) chip and Electronic Components. It’s a complete computer with all of the necessary components on a single chip, including the CPU unit, ROM, RAM, I/O ports, serial ports, and timers, among others.

It no longer requires external additives to complete a task, making it an excellent choice for embedded and small industrial devices. PIC, 8051, AVR, and other microcontrollers are among the most common.

Microcontroller Application

Microprocessor-primarily based totally structures are as a result determined anywhere nowadays and now no longer simply in computer systems and smartphones: in computerized checking out of products, velocity manage of motors, site visitors mild manage, verbal exchange equipment, television, satellite tv for pc verbal exchange, domestic appliances, along with microwave oven, washing machine, gaming controller, business controllers or even specialized programs along with navy programs.

Handheld devices

Hand-held devices, such as smartphones, tablets, and portable media players, now have powerful microprocessors as an alternative, allowing them to compete with computers. And CPUs are becoming more complex as time goes on, with more cores. Originally, processors were unmarried middles, followed by Quad-middle, Hexa-middle, Octa-middle, and now even Deca cores. The majority of modern CPUs are 64-bit. With the Graphics Processing Unit (GPU) being secured inside cell processors, these devices can now give extremely high-quality graphics, Virtual Reality capabilities, 3-D functionality, and 4k recording, as well as a higher level of power efficiency due to the sophisticated processor generation.

Example of Handheld Devices

Below this class, MediaTek and Intel are the leading manufacturers. All chipsets produced by MediaTek, a Taiwanese System on Chip (SoC) manufacturer, have a 64-bit architecture thanks to ARM, a British semiconductor and software program layout firm. ARM meeting code comprises of numerous tiny commands rather than fewer but more intricate commands, and ARM has no unnecessary or complex features, making such chips easier to construct.


The latest MediaTek SoCs support speeds of up to 3.0GHz and come with a wide range of cores, including Dual-Core (2 core), Quad-Core (four core), Hexa Core (6 core), and Deca Core (12 core) (10 core). It’s no surprise, therefore, that Chinese phone manufacturers choose MediaTek chipsets. MediaTek CPUs are often regarded as the best in the low-cost microprocessor (for mobile phones) market. The Helio P90 is MediaTek’s most recent CPU. It is said to provide characteristics such as sharp image, better and faster photography, faster and more environmentally friendly gaming, and enhanced networking with dual 4G SIM.


Intel, on the other hand, creates CPUs that are entirely based on the X86 architecture, which supports all major mobile operating systems. Intel Atom CPUs are utilized in the X5 and X7 series, and are among the most essential processors developed by the business. These have a 64-bit architecture and four cores that can run at up to 2.4GHz. Intel Core M is a low-voltage CPU that may be found in mobile phones and laptop computers.


General-purpose computing

Intel and AMD are the market leaders in this sector. Intel CPUs are said to be the best for gaming and other tasks that are mostly single-threaded. The ne555p Core i5-9400F, which is both affordable and powerful, deserves special mention. It has six cores, which is more than enough for most programs, and a good clock of 4.1GHz in quick mode. It outperforms the Core i5-7600K from previous generations while also being less expensive. Meanwhile, Intel’s Core i3-8100 processor is the most affordable option. It’s a four-center CPU with a frequency of three.6GHz that doesn’t enable additional boost rates but is fast enough for most PC users.

The Ryzen three 3200G is said to be AMD’s excellent entry-level CPU. Its Zen+ CPU core is powerful enough for 1080p entry-level gaming, while the onboard Vega graphics processors are said to be more environmentally friendly than Intel’s HD graphics. It’s also reasonably priced at a hundred dollars.


High-Performance Computing (HPC) is the process of combining computing power in a way that results in far greater overall performance than one would expect from a typical computer laptop or notebook, allowing large problems in research, engineering, or business to be solved. As a result, it’s significantly more sophisticated than a simple computer notebook. These computer systems, often known as supercomputers, have a higher overall performance level than a general-purpose laptop. Quantum mechanics, climate forecasting, weather research, oil and fuel exploration, molecular modeling (computing the systems and homes of chemical compounds, macromolecules, polymers, and crystals), and bodily simulations are among areas where supercomputers are used (simulations of the early moments of the universe, aircraft and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion). They’ve also made a significant contribution to the field of cryptanalysis (studying statistics structures which will observe the hidden components of the structures).


Today, microcontrollers are very widely used in automobiles. A microcontroller is a miniature computer on a single integrated circuit, similar to but less advanced than a SoC, which can include a microcontroller as one of its components. Microcontrollers in vehicles can handle a variety of functions, including complex interactions with sensory structures, vehicle speed, in-vehicle temperatures via air conditioning maintenance, audiovisual multimedia structures, and brake mechanisms. Infineon Tri-center microcontrollers, Atmel AVR microcontrollers, PIC microcontrollers, Renesas microcontrollers, and 8051 microcontrollers are all popular examples in this category.

What is a Microprocessor?

A microprocessor is an integrated circuit (IC) with the best CPU (Central processing unit) and no other critical additives within the (IC) package. Its packing no longer includes RAM, ROM, and other ingredients needed to complete a task. That is why it requires external additives to complete a task.

As a result, microprocessor-based devices are bigger and consume more energy, but they have upgradable memory and high processing capability for doing complex tasks such as gaming, website and software creation, and so on. It has limitless powers.

Microprocessor vs. Microcontroller

External Peripherals

The existence of necessary peripherals or additives such as RAM, ROM, EEPROM. And many more inside a single IC chip is the major differentiator between a microcontroller and a microprocessor.


Microcontrollers are used in tiny portable digital gadgets, toys, and devices due to their compact design. Because of the external peripheral, microprocessor-based complete structures are unwieldy and heavy, and thus are no longer suitable for use in Parallel Resistor Calculator compact devices.


Power Consumption

The microprocessor includes an incorporated energy-saving feature, and the inner peripheral adds to the low-energy consumption motivation. The usage of external peripherals for microprocessors increases the machine’s energy consumption while reducing its energy-saving capabilities. As a result, MCU-based devices are powered by batteries with a long life expectancy. But MPU-based gadgets aren’t suitable for running on conserved energy.


Another contrast is that more than one voltage rail is required. A single voltage rail is desired by a microprocessor. However, the microprocessor’s external peripherals require their own voltage levels. As a result, they require a complex energy delivery system that can provide energy rails with different voltage levels.

Because external RAM, ROM, and other components are required for microprocessor-based systems, they are rather costly. Whereas the microcontroller is a single less expensive chip that can do the task on its own.

Limited and Upgradeable Memory

Note that internal recollection is faster than external remembrance since it is contained in the semiconductor chip.


The MCU’s internal flash remembrance is faster than the MPU’s external flash reminiscence. As a result, during starting, the MCU quickly hundreds and executes this system code. The MCU-based devices are up and running right now, but the MPU-based devices require a while to boot up.


The microcontroller features a built-in, non-upgradable constant limited flash or reminiscence. Where the MPU-based completely machine’s memory may be updated to meet the challenge criteria. This gives the microprocessor-based fully machine an edge over the microcontroller in terms of overall performance and the execution of complex tasks.


The MCUs are termed ASICs because they are intended to solve a specific problem (application-precise Integrated circuit). To complete a single task, it no longer necessitates excessive processing velocity and recollection. On the other hand, Microprocessors are general-purpose devices. And they can handle tasks that need a large number of resources. Meanwhile Microprocessors can provide better overall performance.

The Processing Speed

The MPU that processes velocity-sensitive data is more powerful than the MCU. The former’s processing speed ranges from 1GHz to 4GHz, while the latter’s ranges from eight MHz to 50 MHz. Microprocessors perform more faster. And they can handle more complex tasks such as audio, video, animation material, editing or creating, and so on.
