A microcontroller, often abbreviated as μC or uC, is a single-chip microcomputer designed using Very Large Scale Integration (VLSI) technology. It is also referred to as an embedded controller. The market offers a wide array of microcontrollers with varying word lengths, including 4-bit, 8-bit, 64-bit, and 128-bit options. These compact computing devices are specifically engineered to manage the operations of embedded systems found in a diverse range of applications, such as office equipment, robotics, household appliances, automotive systems, and various other electronic devices. A microcontroller typically includes essential components such as memory, peripheral interfaces, and, most crucially, a processing unit. They are predominantly utilized in devices that require some level of user-applied control.
