Key concepts defined

Semiconductor

A material-typically silicon-that exhibits electrical conductivity between that of a conductor and an insulator, enabling it to control electrical current flow in electronic devices and components.

IoT semiconductor

Specialized semiconductor-based components that provide the core functionality and connectivity of IoT devices, including processing, communication, sensing/actuating, power management, and security. The report categorizes these components based on their intended use at the "design stage" of a product's life cycle.

Microcontroller unit (MCU)

A processor qualifies as an MCU when it integrates memory and peripherals on a single chip. MCUs are self-contained processors that integrate CPU, memory (program + data), and peripherals (I/O, timers, ADC/DAC, etc.) on a single chip. They do not require external memory or controllers to function. MCUs are typically optimized for low power, low cost, and dedicated control tasks in embedded systems such as wearables, smart home devices, and automotive subsystems.

IoT MCU

An MCU qualifies as an IoT MCU when it has integrated wireless connectivity (e.g., Wi-Fi, Bluetooth, ...). IoT MCUs are typically optimized for ultra-low power consumption and typically embed hardware-based security features; however, some may rely on software-based mechanisms to secure lightweight data processing tasks in IoT devices.
