Choosing between Microcontroller and Microprocessor What is a Microcontroller? A microcontroller is a mini-computer on a single semiconductor IC integrated circuit chip. It does not need external components to perform a task which makes it a perfect candidate for embedded and compact devices in industries.

What is a Microprocessor? That is why it needs external components to complete a task. Due to this reason, the devices made from microprocessors are bulkier and power consuming but they have up-gradable memory and high processing capacity for performing complex tasks such as games, website and software development, etc.

Differences Between Microprocessor and Microcontroller: Microcontroller Microprocessor It is a mini-computer capable of performing a task on its own.

Examples: , etc. It is the central processing unit of the computer. It is used in the embedded system and specific applications. It is used in computers as it is the brain of a computer.

It is used in compact devices because it does not need external components. It needs external components thus the devices made it are bulkier. Due to a few numbers of external components, the power consumption is very low. Thus it can be powered using batteries. The external components require extra power to perform. Thus they are not suitable to run on batteries. It has an internal fixed amount of memory that cannot be upgraded.

The external memory is upgradeable and can be easily varied to meet the task. Due to on-chip flash and memory, they are fast in loading the program and instructions. Hence fast execution at startup. Due to external memory, the programs take some time to load which makes it relatively slow. The microcontroller also has a power-saving system for the idle condition that decreases the power consumption The microprocessors do not have the power-saving function, they consume energy in idle condition.

Its processing speed is 8Mhz to 50Mhz. While the microprocessor processing speed is above 1Ghz. It can perform complex tasks. The MCU can support upto p High-definition video. It can support above p high-definition video. It can support USB 2. The MCU is application-specific i. It is designed to perform complex and complicated tasks to utilize its high memory. It is cheap and having low power consumption thus they are perfect for cost-effective, battery-operated electronics.

It is expensive and power-consuming having high processing speed thus they are perfect for high performance of complex tasks. Due to the compact design of microcontroller, they are used in mini portable electronic gadgets, toys and devices. While the microprocessor-based systems are bulky and heavy due to the external peripheral, they are not suitable to be used in small devices.

Differences based on Power Consumption The microcontroller has a built-in power-saving feature and the internal peripheral also factors in to cause of low power consumption. The external peripherals used for microprocessors increase the power consumption of the system including the lack of power-saving feature.

Thus the MCU based devices are powered using batteries with long life expectancy, while the MPU based devices are not suitable to run on stored powered. Another difference is the requirement of multiple voltage rails. A microcontroller needs a single voltage rail. However, the external peripherals connected with the microprocessor need different voltage levels. Thus they need a complex power supply that can provide power rails having different voltage levels. Differences based on Limited and Upgradeable Memory Quick note; Internal memory is faster than the external memory because it is embedded within the semiconductor chip.

Thus the MCU quickly loads and executes the program code at startup. The microcontroller has a built-in fixed limited flash or memory which cannot be upgraded. This gives an edge to the microprocessor-based system to outperform the microcontroller in performance and executing complex tasks.

It does not need high processing speed and memory to perform a single task. While the microprocessors are general-purpose devices that can handle tasks that need a huge amount of resources and can provide better performance.

It is the first crucial step in its development. For the video above p, MPU is a better choice. USB 3. The energy-saving during idle conditions increases the battery life by ten folds. The memory of MCU is limited. It straight-up loads the program from its firmware. The conclusion of the above-mentioned points is that MPU is a better choice for processing a large amount of data, having high processing speed, supporting video resolution greater than P including high-resolution GUI and supporting USB 3.

MCU is a better choice for battery-operated, compact and inexpensive product development where its job is to utilize its low memory to control sensors, actuators and motor to perform a specific task cost-effectively.

Your first choice of selection between microcontroller and microprocessor should be the microcontroller. Because almost any project idea can be implemented using a microcontroller like Arduino etc.

Although some projects may need a microprocessor to perform complex tasks like speech recognition, facial recognition Image processing , artificial intelligence AI that uses a huge amount of memory. You can also use both in a project separately to perform separate functions effectively.

Like controlling the sensors and motors in a robot using MCU and processing the large amount of data from camera and microphone using MPU. Related Posts:.
