Question

Write the main difference between a microcontroller and a microprocessor. Why do smart home appliances have a microcontroller instead of a microprocessor embedded in them?

Answer 1

The microcontroller is a small computing device that has a CPU, a fixed amount of RAM, ROM, and other peripherals all embedded on a single chip as compared to a microprocessor that has only a CPU on the chip.
Microprocessors contain a CPU and it requires adding RAM, ROM, and other things to do a task that requires more space. But in the case of microcontrollers, they don’t require external parts as it already consists of CPU, RAM, ROM, and other things. So a microcontroller requires less space. That is the reason smart home appliances have a microcontroller instead of microprocessors embedded in them.
