To get to know how to choose correct controller for your project click here! Brief overview: I think we have covered all major aspects. It’s simple and inexpensive with less number of instructions to process.
It’s complex and expensive, with a large number of instructions to process.
It’s useful for application-specific systems. It’s useful for general purpose applications that allow you to handle loads of data. Microcontroller based systems run up to 200MHz or more depending on the architecture. Microprocessor-based systems can run at a very high speed because of the technology involved. It uses an external bus to interface to RAM, ROM, and other peripherals. It is a byproduct of the development of microprocessors with a CPU along with other peripherals. It is a central processing unit on a single silicon-based integrated chip. These are based on Harvard architecture where program memory and data memory are separate. These are based on the von Neumann model where program and data are stored in the same memory module. The microprocessor has a smaller number of registers, so more operations are memory-based. Most of the microcontrollers offer power-saving mode. Most of the microprocessors do not have power-saving features. So it can be used with devices running on stored power like batteries. Therefore, it is not ideal for the devices running on stored power like batteries.Īs external components are low, total power consumption is less. The inbuilt finite memory helps to improve the speed of operations.ĭue to external components, the total power consumption is high. We can connect external memory in ranges of Mbytes and even Gbytes. It increases the overall cost of the system high. The presence of peripherals such as RAM, ROM, Input-output, and Timers are In-built. We need to connect peripherals externally. This gives a major clarity between both, but let’s dig deep some technical differences. We can see microprocessor is part of a microcontroller with extra memory, I/O ports, and peripherals such as timer and counters. The real story about microprocessor and microcontroller difference is here!!! 3) Difference between microprocessor and microcontroller: Calculator, Washing Machine, ATM machine, Robotic Arm, Camera, Microwave oven, Oscilloscope, Digital multimeter, ECG Machine, Printer so on and so forth. The applications easily connect with concepts, so let’s find out day to day life examplesĮ.g. Hence, the output depends on the input given by the user or sensors or predefined inputs. As per application, the process is fixed in microcontroller. Once the program is embedded on a microcontroller chip, it can’t be altered easily and you may need some special tools to reburn it. The microcontroller is designed for a specific task or to perform the assigned task repeatedly. Microprocessors are not made for a specific task as well as they are useful where tasks are complex and tricky like the development of software, games, and other applications that require high memory and where input and output are not defined.ĭo you understand? I think a bit, but it’s ok, let’s understand by some daily life examplesĪ) Household devices: Complex home security, Home computers, Video game systems and many more.ī) Transportation and Industrial Devices: Automobiles, trains, planes, Computer servers, high tech medical devices, etc.ĭid you notice! All the above applications are complex and they need to process all complicated data. These all other parts are connected externally. It only contains a CPU (central processing unit) but there are many other parts needed to work with the CPU to complete a process. In simple words, The microprocessor is useful in very intensive processes.
