UNIT I. A microprocessor is a multipurpose, programmable, clock-driven, register-based electronic device that reads binary instructions from a storage device called memory, accepts binary data as input and processes data according to those instructions and provide results as output.. Get Free Android App | Download Electrical Technology App Now! It is used in compact devices because it does not need external components. While the microprocessor processing speed is above 1Ghz. Most common series of the microcontroller are PIC, 8051, AVR, etc. Examples of microprocessors are Pentium, Intel  I3, I5 etc…. 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. Microcontroller is commonly used for application specific purposes like in embedded systems. Microprocessor and Microcontroller Notes Pdf – MPMC Pdf Notes. It was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959, and first demonstrated in 1960. The microcontroller has one or two operation codes for moving data from external memory to CPU (Central processing input). Microprocessor Tutorials. How to Calculate the Battery Charging Time & Battery Charging Current – Example. What is a computer? " Discussion. You can also use both in a project separately to perform separate functions effectively. It is expensive and power-consuming having high processing speed thus they are perfect for high performance of complex tasks. It does not need external components to perform a task which makes it a perfect candidate for embedded and compact devices in industries. . Micro Controller is the heart of an embedded system.

Download link is provided for Students to download the Anna University EC6504 Microprocessor and Microcontroller Lecture Notes,SyllabusPart A 2 marks with … As you already know, support devices are external in a microprocessor-based system where as support devices are internal for a microcontroller. Generally microcontrollers have power saving system, like idle mode or power saving mode so overall it uses less power and also since external components are low overall consumption of power is less. Microprocessors and Microcontrollers is an established textbook for engineering students pursuing a course in electrical and electronics, electronics and communication, computer science, and information technology. Microprocessor: Microcontroller: Microprocessor is commonly used in general purpose applications like in a computer systems. Another difference is the requirement of multiple voltage rails. Hence fast execution at startup. A microcontroller based system can perform single or very few tasks. There has been a great misunderstanding in difference between Microprocessor and Microcontroller since both the IC are designed for Real life use. The microprocessor is the heart of the system and the microcontroller is the brain of the system. Both ICs have different applications and have their own advantages and disadvantages. Our website is made possible by displaying online advertisements to our visitors. The AVR and ARM processors are of this category. It performs less complicated tasks and less complex operations. The MPU needs an operating system (OS) while MCU does not need an operating system. Due to the external connection of multiple peripheral units the power consumption increases. Fig. A microprocessor is a component used for high processing applications. The connections of peripherals make the system bulky. It uses more RAM and can vary from 512MB to 32GB. It is cheap and having low power consumption thus they are perfect for cost-effective, battery-operated electronics. The processing speed of the microcontrollers is ranging from 8 MHz to 50 MHz. A little History ! 6. EC6504 MICROPROCESSOR AND MICROCONTROLLER Score more in your semester exams Get best score in your semester exams without any struggle. MICROPROCESSOR : MICROCONTROLLER : Description : A microprocessor is a central processing unit used to perform tasks such as arithmetic and logic operations, system controlling and storing of data. • In Microprocessor more op-codes, few bit handling instructions. Microprocessor only have CPU in the chip like most of the Intel Processors but Microcontroller also have RAM, ROM and other peripherals along with the CPU or processor. A microprocessor has a comparatively large number of data transfer instructions as compared to a microcontroller.This is so because in case of microprocessor the code or data is transferred between the microprocessor and external memory. While the MPU’s upgradable memory is best suited for applications that utilize a large amount of memory. It follows Von-Neumann architecture. Microprocessor Microcontroller; 1: Microprocessor acts as a heart of computer system. it functions are unlimited. It can support USB 2.0 with max speed of 480 Mbits/sec. Please consider supporting us by disabling your ad blocker. The general microcontroller consists of the processor, the memory (RAM, ROM, EPROM), Serial ports, peripherals (timers, counters) etc. We depends on ad revenue to keep creating quality content for you to learn and enjoy for free. It can perform complex tasks. So, there are no memory-related constraints. GUI (Graphical User Interface) can be implemented using both MCU and MPU. it is designed for performing a single specific task. It forms the core of the processing system of a computer. Microprocessor works much faster and can perform complex tasks faster like audio, video, animation content,  editing or designing, etc. Microcontroller: Microprocessor is the heart of Computer system. 2. It is not necessary to be on a single chip (remember this point, not in a single chip). Thus they are not suitable to run on batteries. 8. Its packaging does not contain RAM, ROM and other components required to perform a task. MICROPROCESSOR : MICROCONTROLLER : Description : A microprocessor is a central processing unit used to perform tasks such as arithmetic and logic operations, system controlling and storing of data. Unfortunately, most of them think that Microprocessor and microcontroller are the same. Microprocessors and Microcontrollers by Dr.J.S. Conclusion: Microprocessor vs Microcontroller. Microprocessor, Microcontroller, Operating Systems. However, the external peripherals connected with the microprocessor need different voltage levels. General microprocessors have the speed of processing about 1 GHz. Thus, this is all about the difference between microprocessor and microcontroller. Both the program and the data are stored in the same memory. Complex mathematical calculations which involve floating point can be performed with great ease. How To Calculate Your Electricity Bill. Why Does the Heating Element Glow but Not the Cord of Heater. The selection between a microcontroller (MCU) and Microprocessor (MPU) depends and affects your project. Microprocessor और Microcontroller के बीच का difference: Microprocessor: Microprocessor एक IC है जिसमे अन्दर सिर्फ CPU होता है मतलब सिर्फ processing power होती है जैसे-Intel का pentium 1,2,3,4, core 2 duo, i3, i5, i7 इत्यादि. The lesser registers are used because the number of operations is based on memory. For the video above 720p, MPU is a better choice. 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. Contains. Just for a one […] “What is the difference between microprocessor and microcontroller?” A simple and basic electronics question, yet people still confuse these two components for the same thing. Architecture: The microprocessor uses Von Neumann architecture where data and program present in the same memory module. 3) Working of Microprocessor and Microcontroller. Micro controllers offer software protection where a microprocessor base system fails to offer a protection system.
