IoT & IIoT Semiconductors
The Internet of Things (IoT) and its industrial counterpart (IIoT) represent one of the broadest and fastest-growing markets for semiconductors. From smart home devices and wearables to factory automation, energy grids, and logistics, IoT systems integrate connectivity, sensors, compute, and security into cost-sensitive and power-constrained designs. Industrial IoT adds stricter requirements for reliability, ruggedness, and real-time performance, with edge AI enabling smarter local decision-making.
Semiconductor Roles in IoT & IIoT
- MCUs / MPUs: Ultra-low-power microcontrollers and application processors for local compute.
- Sensors: Environmental, motion, position, and imaging sensors feeding real-time data streams.
- Connectivity ICs: Wi-Fi, Bluetooth, Zigbee, LoRa, NB-IoT, 5G modems, and industrial Ethernet PHYs.
- Edge AI Accelerators: NPUs and AI extensions in MCUs/SoCs for vision, predictive maintenance, and anomaly detection.
- Power Management: PMICs, battery gauges, energy harvesting ICs, and ultra-efficient regulators.
- Security Silicon: Hardware roots of trust, crypto accelerators, secure enclaves, and TPM-like devices.
- Industrial Interfaces: CAN, Modbus, EtherCAT, and TSN-enabled chips for factory automation.
