In a embedded system microcontroller is used more. Let us understand the advantage of using micro controller over the microprocessor.
Advantages of microcontroller

• Low cost
• Small Packaging
• Programmable and Re-Programmable
• Lots of Input output ports (not for all)
• Easy integration with circuits
• Consumes low power
• Consumes less space
• Single purpose
