An embedded controller typically consists of a microcontroller, memory, input/output (I/O) interfaces, and other peripheral components. The microcontroller is the heart of the embedded controller and is responsible for executing the program code that controls the device. The memory is used to store the program code and data, while the I/O interfaces allow the embedded controller to communicate with other devices or systems. By integrating a dedicated controller into a system, designers can optimize the performance and functionality of the system, while also reducing its size, cost, and power consumption.
