Difference between Microprocessor and Microcontroller

In this tutorial I am sharing the difference between Microprocessor and Microcontroller. Before learning the differences, lets first learn about what is microprocessor and microcontroller.

What is Microprocessor?

Microprocessor (µP) is the logic chip that contains all or
most of the central processing unit (CPU) functions on a single integrated
circuit. Microprocessor is a miniature electronic device that contains the
arithmetic, logic and control. It is capable of performing various computing functions;
making functions and making decisions to change the sequence of program
execution.

What is Microcontroller?

Microcontroller (MCU or µC) is a computer on a chip. It is a microprocessor
emphasizing high integration, low power consumption and cost effective as
compared to general purpose microprocessor. Microcontroller typically
integrates additional elements such as read-write memory for data storage, read
only memory, flash memory for permanent data storage, peripheral devices and
input/output interfaces.
This was a brief introduction; let’s now take a look on the difference
between microprocessor and microcontroller.

Difference between Microprocessor and Microcontroller

Characteristics
Microprocessor
Microcontroller
Intention
Microprocessor is designed to be general purpose. So, microprocessor is
used to perform certain task.
Microcontroller is a specialized form of microprocessor that is
designed to be self-sufficient and cost effective. So, microcontroller is
used to perform particular task.
Architecture
Microprocessor is a silicon chip represents central processing unit,
which performing arithmetic and logical operation according to information.
Microcontroller is an integrated chip that contains CPU, RAM, ROM,
Registers, Timer and input/output ports.
Dependency
It is dependent unit, requires the combination of timers, controllers
memory chips, etc.
It is a self-functional unit and it doesn’t require external controller,
timer, memory chips, etc.
Market requisite
Microprocessor is focused for any general purpose where quality of performance
is essential.
Microcontroller is focused for embedded market where quality of
performance is not so require
Power saving features
Many power saving features in microprocessor is limited
Many power saving features are present in the microcontroller
