Microcontroller Unit(MCU)
A microcontroller is a self-contained system with peripherals, memory and a processor that can be used as an embedded system. Most programmable microcontrollers that are used today are embedded in other consumer products or machinery including phones, peripherals, automobiles and household appliances for computer systems. Due to that, another name for a microcontroller is "embedded controller." They are designed to perform specific tasks. Specific means application where the relationship of input and output is defined.
In the year 1969, Intel company put the entire CPU inside a single IC. This IC is called Microprocessor.
Microprocessor
A microprocessor incorporates the functions of a CPU on a single integrated circuit or a few integrated circuits. They are designed to perform arithmetic and logic operations that make use of data on the chip. General purpose microprocessors in PCs are used for multimedia display, computation, text editing and communication. Several microprocessors are part of embedded systems.History
The Center of computer is CPU. Initial days, the CPU was built with Vacuum Tubes, Transistors, IC etc.
In the year 1969, Intel company put the entire CPU inside a single IC. This IC is called Microprocessor.
Microcomputer is built using this Microprocessor as CPU, RAM, ROM, I/O etc.
The logic part of microcomputer is put inside an IC and called Microcontroller.
