Understanding the Key Features of Microcontrollers
A microcontroller, or MCU (Microcontroller Unit), is a compact, cost-effective integrated circuit (IC) designed to perform specific tasks within embedded systems. Essentially a tiny computer embedded on a single chip, a microcontroller is a programmable silicon chip that operates using a clock-driven, register-based system. It accepts input, processes it according to instructions stored in its memory, and then outputs the results. How Microcontrollers Work Microcontrollers function by processing data through their central processing unit (CPU). Data enters the microcontroller through input ports, gets processed, and the output is delivered via output pins. This process is powered by a synchronous sequential logic circuit, which ensures that the output depends not only on current inputs but also on the history of previous inputs. The clock signal within synchronous sequential circuits determines when the device's state changes. This timing ensures simplicity and reliability i...
