Microcontroller Architecture To understand how microcontrollers work, let’s explore their internal architecture. Processor (CPU) The processor, or CPU, is the brain of the microcontroller . It fetches instructions from memory, decodes them, and executes the corresponding operations. The CPU typically includes an arithmetic logic unit (ALU) for performing mathematical and logical operations, registers for temporary data storage, and a control unit for managing the flow of instructions ... Learn what a microcontroller is, how it differs from a microprocessor, and what are its main components and functions. Explore the rise of microcontrollers and their applications in various fields like automobiles, consumer electronics and test equipment. Different Types of Microcontrollers and their Applications What is a Microcontroller ? A microcontroller is a semiconductor IC (integrated circuit) chip consists of multiple functional block such as CPU, ROM, RAM, Timer, Counter & interrupts etc. It is essentially a small computer with all peripheral inside a single package.
