![]() ![]() ![]() It’s a high-end device with a microprocessor, memory, and input/output ports all on a single chip. ![]() It’s designed to perform application specific tasks that require a certain degree of control such as a TV remote, LED display panel, smart watches, vehicles, traffic light control, temperature control, etc. Microcontroller is like a mini computer with a CPU along with RAM, ROM, serial ports, timers, and IO peripherals all embedded on a single chip. In simple terms, it’s a fully-functional CPU on a single integrated circuit that is used by a computer system to do its work. They are designed for general purpose applications such as logical operations in computer system. It consists of the ALU which handles all the arithmetic and logical operations the Control Unit which manages and handles the flow of instructions throughout the system and Register Array which stores the data from memory for fast access. They are to be added externally to make them functional. Microprocessors don’t have RAM, ROM, IO pins, Timers, and other peripherals on the chip. ![]() It’s the heart of a computer system which is designed to perform loads of tasks that involve data. Microprocessor is a silicon-based integrated chip with only a central processing unit. However, they have their fair share of differences too. Both microprocessor and microcontroller are often used in synonymous with each other because of the fact that they share common features and they are specifically designed for real time applications. If microprocessor is the heart of the computer system, microcontroller is the brains. The advancements in microprocessor technology have made personal computing faster and reliable than ever before. From the first commercial microprocessor (4-bit 4004) which was developed by Intel in 1971 to the more advanced and versatile 64-bit Itanium 2, the microprocessor technology has shifted to a whole new realm of next-generation architectures. It’s surprising how a small piece of technology changed the face of personal computing. ![]()
