manufacturer. The instruction set of a microprocessor is provided in two forms: binary Microcontroller- microprocessor with built-in memory and ports and can be .. How does microprocessor differentiate between data and instruction? 4. Microcomputers (with CPU being a microprocessor) 2- Microcontroller (MCU) logic device that executes binary instructions in a sequence . Many difference manufacturers: Philips, Dallas/MAXIM Semiconductor, etc. If microprocessor is the heart of the computer system, microcontroller is the brains . Both microprocessor and microcontroller are often used in.

User assumes all risk of use, damage, or injury. You agree that we have no liability for any damages. What is Microprocessor? The microcontroller has very low external components. So it consumes very low power supply as compared to the microprocessor.
Power Saving Feature: The microcontroller can have multiple modes of operation such as higher performance, balance, idle or power saving mode. Most of the Microprocessor does not have this power saving feature. Processing Speed: The microprocessor has very less internal registers.
It has to rely on external storage. So all the memory operations are carried out using memory-based external commands.
What is Microcontroller?
Results in high processing time. The microcontroller has many registers for instruction execution. Fetching data and storing data require internal commands.
So its execution and processing time are lower than the microprocessor. Examples: Intel Pentium series processor, core 2 duo, dual-core, Intel i3, i5 are the examples of Microprocessor that are widely used.
If you are preparing for placement interviews or any computer science examination, understanding the difference between microprocessor and microcontroller is very important.
Many of the company interviewers asked questions about it. If you have any question, feel free to comment below.
Since external components are low, total power consumption is less and can be used with devices running on stored power like batteries.
Difference between Microprocessor and Microcontroller
Most of the microprocessors do not have power saving features. Most of the micro controllers have power saving modes like idle mode and power saving mode.
This helps to reduce power consumption even further. Since components are internal, most of the operations are internal instruction, hence speed is fast. Microprocessor have less number of registers, hence more operations are memory based. Micro controller have more number of registers, hence the programs are easier to write.Computational capacity of microprocessor is very high. It stores data temporarily and keeps intermediate results.
There are three basic characteristics used to differentiate microprocessors.
Difference Between Microprocessor and Microcontroller
They are to be added externally to make them functional. Generally power consumption and dissipation is high because of the external devices. Since then, it took a phenomenal success in its development and usage. Microcontrollers can be divided into two types based on their memory structures: Embedded Memory and External Memory.
Drivers are required to support peripherals. Processing Speed: Setting aside the differences between the microprocessor and microcontroller, it is clear that a microprocessor cannot replace a microcontroller and vice versa.
