System On Chip (SoC)A system on chip (SoC) is an integrated circuit (IC) that incorporates all of the components necessary to build a complete system on a single chip. This includes a microprocessor, memory, input/output (I/O) interfaces, and other supporting circuits. SoCs are commonly used in embedded systems, where they are used to provide the computing power and other functionality needed to control a particular device or system. Because an SoC combines many different functions on a single chip, it can be smaller, more power-efficient, and less expensive than a system that uses multiple separate ICs.
