System on Chip (SoC) in IoT refers to an integrated circuit that combines all essential electronic components—such as CPU, memory, input/output interfaces, and communication modules—onto a single chip. This design simplifies hardware architecture and improves efficiency in Internet of Things (IoT) devices.
SoC technology exists to address the growing need for compact, energy-efficient, and high-performance systems. Traditional hardware required multiple chips to perform different functions, which increased size, power consumption, and complexity. With IoT devices becoming smaller and more connected, SoC enables seamless integration while reducing physical footprint.
In simple terms, an SoC acts as the “brain” of IoT devices, handling processing, communication, and control within one compact unit. This is especially useful in applications such as smart homes, wearable devices, industrial automation, and connected vehicles.
