Subjective Question Answer What are advantages and disadvantages of microcontroller

Lower cost because many elements of the processor are contained within the one chip resulting in lower chip cost.
Lower power consumption.
Integrating all consumption onto one chip enables processor to be optimised for a given application.
Disadvantages of Microcontroller are:
Less flexibility because all components are integrated into the one chip.
Limited performance because the size of memory is limited by what can be accommodated on the chip.
MCUs tend to be application specific so the choice may be limited.
