Embedded processors and controllers are specialized computer processors that are designed to be integrated into a larger system or device, rather than being used as a standalone computer. Microcontroller units (MCUs) are a type of embedded processor that is typically used in small, low-power applications such as sensors and other types of electronic devices.
MCUs are often referred to as microprocessor units (MPUs) or system-on-a-chip (SoC) devices. These processors are typically much smaller and more power-efficient than general-purpose processors, and are designed to handle specific tasks or functions within a system. They typically include a CPU, memory, and peripherals such as timers, analog-to-digital converters, and communication interfaces on a single chip.
