MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -microcontroller (MCU) A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip.

Detailed explanation-2: -A microcontroller (MCU for microcontroller unit, also MC, UC, or C) is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.

Detailed explanation-3: -A microcontroller can sense the world through its input pins. Input pins are either digital or analog. Digital inputs are the opposite of digital outputs-they expect to be set to either 0 or 5 volts by some external device. For each digital input there is a bit in the microcontroller’s memory that reflects its value.

Detailed explanation-4: -The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output.
