An embedded controller, also known as an embedded microcontroller or embedded system controller, is a specialized type of microcontroller that is designed to perform specific tasks within a larger system. It is a compact and self-contained computing unit that integrates processing, memory, input/output interfaces, and often other components, all within a single chip or package.
