The functional differences between a microcontroller and a microprocessor are important for embedded systems engineers and product developers in the electronics industry. While both types of components are essential for designing and building various kinds of electronic devices, their definitions alone can make it difficult to distinguish between them.
Microcontrollers can be categorized as small computers or "supercomputers" that are made from a single integrated circuit chip that contains one or more cores of computing power, along with other peripherals (memory, serial interfaces, timers, programmable I/O peripherals, etc.).
A microprocessor refers to a computer processor that incorporates the functions of a central processing unit (CPU) onto just a few (and often only one) integrated circuits, which are used to carry out the operation of that computer.
There are many similarities between microcontrollers and microprocessors on the surface. They are both examples of single-chip processors which have increased reliability and reduced the cost of processing power, thereby accelerating the proliferation of computing technology. Each of these processors executes computing logic on a single chip, and they are found in millions of electronic devices worldwide.
Here's a blog post that compares microcontrollers and microprocessors to help clarify the differences between them. You will gain a clear understanding of which of these components should power your next computer engineering project as we examine every difference between a microcontroller and a microprocessor, from architecture to applications.

What's the Difference Between a Microcontroller and Microprocessor?
Choosing the right computer processor for your project matters a lot. It affects how you design and what results you get. So, knowing the main options and their unique features is essential. Let's look at how a microcontroller and microprocessor differ.
Microcontroller vs. Microprocessor Architecture
While both do similar tasks, their architectures are quite different. A microcontroller has everything it needs for computing on a single chip. That means the CPU, memory, controls for interruptions, timers, serial ports, and more are all on that one chip. No external circuits are needed.
On the other hand, a microprocessor includes a CPU and some extra chips that supply memory, interfaces, inputs, timers, and other parts. People sometimes use "microprocessor" and "CPU" interchangeably, but a microprocessor is like a single chip that has a CPU. This chip can connect to external stuff like a control bus or data bus for inputs and outputs.
So, microcontrollers are self-contained, while microprocessors deal with external things. These differences have their own pros and cons.

Microcontroller vs. Microprocessor Applications
Microcontrollers and microprocessors both use CPUs in computing. They have somewhat separate applications, though.
Microprocessors need extra chips to make a microcomputer system. They are great for personal computers where you need powerful processors for different jobs. You can easily upgrade parts like RAM in microprocessors.
Microcontrollers are all-in-one chips that use low power and do a single job. They're mostly used in embedded systems where things have to run on their own for a long time.

Three Key Differences: Cost, Speed, and Power
Cost
In general, microcontrollers tend to be less expensive than microprocessors, as microprocessors tend to be manufactured with more expensive devices that will use external peripherals to boost performance. They are also significantly more complex, as they are intended to perform a variety of computational tasks, while microcontrollers usually perform a particular function. In order to support more complex computational tasks, microprocessors require a robust external memory source.
Code for specific applications is written and compiled by engineers and uploaded to a microcontroller, which contains all of the computing features and components needed to execute the code internally. Since microcontrollers have narrow individual applications, they often require less memory, computing power, and complexity than microprocessors, which is why they are more affordable.
Speed
A high-quality microcontroller differs significantly from industry-leading microprocessor chips when it comes to overall clock speed. As a result, microcontrollers are designed to handle specific tasks or applications, while microprocessors are designed to handle more complex, robust, and unpredictable computing tasks.
Using just the right amount of speed and power to accomplish a given task is one of the key design advantages associated with microcontrollers. That means using just the right amount of power and speed to accomplish the task. Therefore, many microprocessors are clocked at speeds of up to 4 GHz, while microcontrollers operate at 200 MHz or less.
While on-chip components help microcontrollers perform functions quickly, microprocessors sometimes operate more slowly as a result of their dependence on external peripherals.
Power Consumption
There are several benefits associated with microcontrollers, including their low power consumption. Microcontrollers can perform a variety of tasks at relatively low speed, which means that they use less power than processors with robust computational capabilities. An implementation's power consumption is an important factor: a processor that consumes a lot of power may require an external power supply, whereas a processor that consumes a small amount of power could be powered for a long time by just a small battery.
A microcontroller can be much more cost effective than a microprocessor for tasks that require little computational power.

Microcontrollers for Embedded Systems
Microcontrollers work well for embedded systems:
- They have everything on one chip.
- They're made for one job.
- They can be optimized.
- They use low power.
- They're cost-effective.
Summary
In the end, microcontrollers and microprocessors are different ways of organizing and optimizing a computing system based on a processor. A microprocessor houses a more powerful CPU on a single chip that connects to external peripherals, as opposed than a microcontroller which houses the CPU and all peripherals on the same chip. In general, microprocessors are more useful for applications requiring more complicated and versatile computing operations than microcontrollers, which are optimized for a low-power, dedicated applications - ideal for embedded systems.
