integrated circuit (IC) device used for controlling other portions of an electronic system, usually via a microprocessor unit (MPU), memory, and some peripherals. These devices are optimized for embedded applications that require both processing functionality and agile, responsive interaction with digital, analog, or electromechanical components.
The most common way to refer to this category of integrated circuits is “microcontroller" but the abbreviation “MCU” is used interchangeably as it stands for “microcontroller unit”. You may also occasionally see “µC” (where the Greek letter mu replaces “micro”).
“Microcontroller” is a well-chosen name because it emphasizes defining characteristics of this product category. The prefix “micro” implies smallness and the term "controller" here implies an enhanced ability to perform control functions. As stated above, this functionality is the result of combining a digital processor and digital memory with additional hardware that is specifically designed to help the microcontroller interact with other components.
As practitioners of Electronics Engineering, understanding microprocessors is a must whilst coping up with today's rapidly advancing technology. For starters, microprocessors serve as the brain of many computers and gadgets that we use in our day to day life whether they be personal or professional. The transitional trend of the present to the near future is inclusive of IoT state of the art technology, which relies on microcontrollers in transmitting and receiving the data used to control multiple devices remotely. this is rather crucial to us students as we are currently training ourselves in creating sketches for IoT related projects using Arduino and similar media with application of I/O programming.
However, before making innovations, it is always better, in any particular field, to master the basics and understand how the historical technology works and their transformation to the current technology. Hence, in this subject, we were taught how microprocessors started. included in the discussions are being familiar with the different parts of microprocessors, like the varying types of memories, registries, and how data are transferred in and out of these virtual cabinets. this is through furthering our knowledge on assembly language to program building and debugging.
Additionally, we also learned about speaker and relay interfacing, one-time programming interrupts, and hardware timers for seven segment displays and analog interface.
Finally, this subject gave me extensive understanding on the internal operation of microprocessors with regards to its application on microcontrollers. Now I look at computers and little bots and immediately know how their robotic brains function.
