![]() The microcontroller uses Harvard architecture, where data and program are stored in a separate memory module. It uses Von Neumann architecture in which data and programs are present in the same memory module. The most important component in a microcontroller is the clock, as it determines how fast a microcontroller will run, which could impact certain aspect of your applications such as resolution, response, power consumption, etc. ![]() It has a memory used by the microcontroller to store programs that are specific to one single task it is dedicated to. The microprocessor will jump from one location to another and thus take a decision after each jump. The data in this is capable of moving from one location to another.Ī Program Counter register stores the reference of the next instruction. It does operations like addition, subtraction, multiplication, division and logical operations with the help of an Arithmetic and Logical Unit (ALU). The microprocessor performs the given three things while doing so: Just like any other computer, a microcontroller has a Central Processing Unit that allows it to perform all the calculations and logic operations in the background.Ī Microprocessor will take instructions in machine language, execute them and then command the processor what it has to do. Consider an example of a personal computer that can perform a number of tasks or run a variety of programs simultaneously such that you can listen to music while typing in a word processor all at the same time.Ī microprocessor is a programmable device that takes some input, performs some logical and arithmetic operations on it and produce some desired output.Ī microcontroller is a computer that is typically dedicated to a single task. In the simplest of terms, a microcontroller is basically a computer that comes in a variety of packages and sizes. It is impossible to perform any computations without a microprocessor. A microprocessor is a computation engine in a single chip. It is basically the brain of the microcontroller. MICROPROCESSORĪ microprocessor incorporates the functions of a Central Processing Unit (CPU) on a single integrated circuit. Let us discuss the topmost differences between Microprocessor vs Microcontroller. Microprocessor vs Microcontroller Comparison Table On the contrary, the total cost of applications made with microprocessors is way too high when compared with the microcontrollers as the number of peripheral components required for the systems is much more than those of the microcontroller.The external components that are required by the applications made with microcontrollers are less in number, so the cost is minimal. The complementary metal-oxide-semiconductor technology used in making a microcontroller is far cheaper than the material used in making microprocessors.Microcontrollers have peripherals embedded in a single chip, making them much more compact than the microprocessor. As we can see, the key difference between a microprocessor and a microcontroller is the presence of external and internal components.The undeniable thing is that both have their own specific purpose and use, which makes them different over a wide aspect that many people often do not know. Microprocessor and Microcontroller are some very basic and key electronic components that are a lot different from each other based on their architecture. ![]() ![]() Let us discuss some of the major differences between Microprocessor vs Microcontroller.
