Let’s understand in detail what are the difference between Microprocessor and Microcontroller. Microprocessors and microcontrollers are both essential components in the field of electronics and computing, but they serve different purposes and have distinct architectures and applications. Here are the key differences between them: What is Microprocessor? A microprocessor is a central processing unit (CPU) […]
Let’s see block diagram of microcontroller in detail. microcontroller is a compact electronic device that integrates a central processing unit (CPU), memory (both RAM and ROM), input/output (I/O) ports, and various peripherals onto a single integrated circuit (IC chip) for specified tasks. Unlike general-purpose microprocessors found in personal computers, microcontrollers are designed for specific tasks […]
