What are the primary structural differences between a microcontroller and a microprocessor?
Answer
A microprocessor relies on external chips for memory and I/O, while a microcontroller integrates the CPU, memory, and peripherals onto a single chip.
A microprocessor typically contains only the Central Processing Unit core, necessitating the use of external memory chips and separate input/output interfaces to operate as a functional system. In contrast, a microcontroller is a system-on-chip design that encapsulates the CPU, volatile RAM, non-volatile ROM or Flash memory, and various peripheral components such as timers and communication interfaces into a single integrated circuit, creating a self-contained unit specifically designed for embedded control tasks.
