Comparing microcontroller and microprocessor in terms of cost is not justified. Difference based on External Peripherals The main difference between a microcontroller and microprocessor is the presence of necessary peripheral or components like RAM, ROM, EEPROM, etc inside a single IC chip. Due to the compact design of microcontroller , they are used in mini portable electronic gadgets, toys and devices. Typically a microcontroller is smaller (only a very small chip), while a microprocessor tends to be bulkier and more complex.

Majority of microprocessors do not have power saving features. The cost of microprocessor based systems is high when compared with microcontroller based systems. The microprocessor cannot be used in compact systems.

It is simple and inexpensive with less number of instructions to process. For example, PIC microcontrollers have only instructions. On the other han a microprocessor is a general purpose oriented tool. Therefore microprocessor is inefficient.

It can be used in compact system. Microprocessor has less number of registers. A microprocessor having a zero status flag. n Sie Mikrocontroller? Usually clock speed of microprocessors are above 1GHz, while microcontroller’s clock speed ranges from 20MHz to 120MHz. As we stated above, a microcontroller is designed for specific application, so it needs only the hardware required for the specific application.

Nobody can till weather a miscellaneous DIP chip is a microcontroller or a microprocessor by just observing how it looks. The key distinguishing parameter is its functionality, and that’s what we’re going to briefly describe hereafter. This memory include EEPROM, SRAM, Flash etc. Both microprocessors and microcontrollers have their advantages and disadvantages. When deciding between the two, you need to look for what application you want to use that.

In contrast, microcontroller performs application oriented operations. Microcontroller based systems run up to 2MHz or more depending on the structure. In microprocessor the main emphasis is on performance hence it aims for the high-end market.

Much like a microprocessor, a microcontroller is the nervous system of a body. Whilst the former “processes” data, the latter “controls” data and peripherals. Indee some of the earliest microprocessor designs have evolved into microcontroller chips.

The power and abilities of MCUs varies hugely. Arduino is a microcontroller based platform (ATMEGA 3for the UNO). In general a Micro-controller is better suited than a microprocessor to anything the requires sensing of inputs.
