Embedded Systems Operations managed behind the scenes by a microcontroller
Microcontroller (MCU) An integrated electronic computing device that includes three major components on a single chip Microprocessor (MPU) Memory I/O (Input/Output) ports. The MPU communicates with memory and I/O using the system bus consisting of: Address bus: unidirectional and carries memory and I/O addresses Data bus: bidirectional; transfers binary data and instructions between MPU and memory and I/O Control lines: Read and Write timing signals asserted by MPU
