introduction microcontroller

What is a microcontroller?

• A type of computer

• A compact integrated circuit with a processor, memory, and peripherals

• A type of software

• An external device for computer storage

How is a microcontroller different from a microprocessor?

• A microcontroller is larger than a microprocessor

• A microcontroller is used in desktop computers, while a microprocessor is used in embedded systems.

• A microcontroller is self-contained with memory and peripherals, while a microprocessor is just the CPU

• A microcontroller is more powerful than a microprocessor

What are the main components of a microcontroller?
