Implementing embedded systems in modern technology has been fundamentally altered by the invention of integrated circuits (ICs). Electronics developers could produce powerful computing devices such as laptop computers and mobile phones if they could integrate transistor circuits onto a single chip. Integrated circuits and microprocessors are two terms that come up frequently when people are talking about the workings of embedded systems.
So, what exactly are these components, how exactly do they differ, and how do they connect to embedded systems? In this post, we will provide some information on their relationship and how they have contributed to the modernization of the embedded systems sector.
What Is An Integrated Circuit?

In the early days of computer manufacturing, vacuum tubes were used to create the logic circuits of the machines. The original computer was not suited for widespread usage because of its complicated and pricey design. It was also somewhat cumbersome. The transistor, a device that regulates current or voltage and switches electrical impulses, helped reduce some of these challenges. Still, it was not without its limitations.
The development of the integrated circuit, often known as an IC, led to a revolution in the use of electronic signals such as transistors, resulting in designs that were both more compact and more lucrative.
An integrated circuit, also known as a microchip or chip, is a wafer made of semiconductor material, most commonly silicon, that comprises a collection different electronic circuits, such as capacitors, resistors, transistors, and diodes, that are connected to carry out a particular function. The integrated circuit is sometimes referred to as a microchip. Depending on the computing power available, a single integrated circuit can include thousands to millions of similar electronic circuits.
Embedded system design relies heavily on integrated circuits since these circuits have contributed to the revolutionization and improvement of the use of electronic circuits. Transistors and resistors were connected via wires on a circuit board before integrated circuits were used. The integrated circuit (IC), however, has made it possible to combine all of these parts into a single, more compact chip.
Integrated circuits, which can be classified as either analog, digital, or a combination of the two, are utilized frequently in constructing electronic devices in today’s modern world. Amplifiers, computer memory, video processors and switches even microprocessors are some of the many applications that can use integrated circuits (ICs).
What Is a Microprocessor?

Although all integrated circuits can be considered microprocessors, not all microprocessors can be regarded as integrated circuits. Microprocessors are intelligent pieces of integrated circuitry, just like Professor X, with many of the same characteristics. It serves as the “brain” of circuits dependent on their ability to compute.
The first microprocessors contained thousands of transistors on the silicon wafer, whereas the number of transistors on a modern microprocessor can exceed billions.
In contrast to other integrated circuits, a microprocessor can be thought of as the “brain” of a computer. It can carry out the mathematical and logical operations that the programmer has instructed. An arithmetic and logic unit (ALU) is one of the components that make up a microprocessor, along with a control unit and a register array.
The computer’s central processing unit, or CPU, is typically what comes to mind first when most people think of a microprocessor. However, the application of microprocessors is not limited to personal computers, mobile devices, and laptops. Microprocessors are also being developed for use in the gaming industry as graphic processing units (GPUs).
Single-board computers like the Raspberry Pi are becoming increasingly popular in the commercial electronics industry thanks to the proliferation of microprocessors. And then there’s the microcontroller, a single chip that combines a microprocessor with memory and input/output peripherals all in one convenient package.
Microprocessors and integrated circuits are two types of electronic components. In electronics design, you will almost certainly run into integrated circuits. It’s possible that interacting with a microprocessor can feel like a Herculean effort at times. The use of a microprocessor in the design process fundamentally differs from that of more conventional integrated circuits.
When working with a microprocessor, you must be aware of the unique factors that come into play.
The microprocessor was created for one reason and one purpose only: to carry out the functions of the software applications. If you are not careful, flooding it with data or requests is pretty easy, leading it to either stop working altogether or become unresponsive. When selecting clock frequencies and operating voltages, you also need to exercise caution; the chip will likely malfunction if either of these parameters is set too high or too low.
Integrated circuits, on the other hand, are devices that are designed for general usage and can be put into many different applications. As a consequence, picking parameters involving them does not require as much careful consideration. Before beginning a project, you should become familiar with the capabilities of the many types of integrated circuits available. This is because there are so many distinct kinds of integrated circuits.
Microprocessor vs Integrated Circuit in Electronics Design
- You will most likely work with integrated circuits in electronics design. It could be a Herculean effort to work with a microprocessor on occasion. Using a microprocessor in the design process differs from using more conventional integrated circuits. You should be aware of the unique concerns that arise when dealing with a microprocessor.
- The primary function of a microprocessor is to execute computer programs. Overloading it with information or queries can quickly cause it to stop responding. You must also exercise caution when deciding on clock frequencies and operating voltages; if either is too high or too low, the chip will most likely fail to function correctly.
- Contrarily, integrated circuits are multifunctional devices that can serve many different functions. This means that less care is needed when choosing parameters for them. Nonetheless, knowing the capabilities of the many types of integrated circuits accessible is necessary before beginning a project.
- If you keep making the same mistakes in your microprocessor-based design, you will likely run into many issues when you build the prototype. Microprocessors are notoriously energy-intensive devices that typically run at hundreds of Hertz or Gigahertz frequencies.
- The significance of the voltage supplied to a CPU should go without saying. Ripples or a sudden voltage drop could disrupt the microprocessor’s stability. High-speed data links added to a microprocessor also provide an EMC danger. Rapid data transfer rates may cause EMI, which can cause problems for nearby electronic devices.
- You must not make any mistakes while using a microprocessor for designing and installing the appropriate PCB layout and analysis tool.
- A microprocessor, in summary, has all the parts of an integrated circuit (CPU, memory, I/O ports, etc.), plus its non-volatile storage for programs (ROM) and data (RAM).
- This way, customers can install software on their PCs without investing in supplementary hardware. Since an integrated circuit has no memory for its instructions or data, it cannot carry out tasks alone.
How Integrated Circuits and Microprocessors Advance Embedded Systems?
Microprocessors and integrated circuits can improve performance and efficiency by streamlining the process of reading and writing data from the system’s memory. Because of this, these embedded systems’ power is increased compared to systems that do not contain these chips.
The use of integrated circuits that are more compact and lighter in weight and microprocessors that give more functionality can now be utilized in the production of many types of devices.
To Show, The Differences Between The Two, Consider The Following Example:
There is a possibility that a digital thermometer uses an integrated circuit. The chip would perform all required calculations and measurements, and the results would either be shown on a screen or saved elsewhere. Due to its compactness, the integrated circuit used in this thermometer can easily be installed inside the device’s housing.
If a microprocessor were to be utilized in constructing a digital thermometer, additional space within the housing would be required. Compared to integrated circuits, the capability of microprocessors to successfully execute complex software is superior. Calculations relating to temperatures, such as averaging temperatures over a while or converting between Celsius and Fahrenheit are possible applications for this information.
Microprocessors excel at difficult tasks, while integrated circuits are at their best in environments with fewer rigorous requirements. However, as the technology for embedded systems continues to advance, more and more electronic devices will indeed contain microprocessors and integrated circuits.
Understanding integrated circuits and microprocessors are necessary for the development of embedded systems. Embedded systems can also be created using these two components. The utilization and incorporation of transistors and other electronic circuits into electronic designs may now be scaled thanks to the development of integrated circuits.
In addition, we wouldn’t have any microprocessors if integrated circuits weren’t around. Microprocessors allow us to embed computer processing unit (CPU) capabilities into devices, enabling the devices we use daily to do complex computations and activities. Even while using these components makes our lives simpler, developing reliable and effective systems can be difficult. Regarding testing and validating systems, having the appropriate debugging and development tools can assist ease the tasks involved.
