Automotive Sector
The automotive industry is undergoing a semiconductor-driven transformation as vehicles shift toward electrification, autonomy, connectivity, and software-defined architectures. Modern EVs and AVs integrate hundreds to thousands of semiconductor devices — spanning power electronics, sensors, networking, infotainment, safety-critical microcontrollers, and high-performance AI compute. Automotive semiconductors must meet stringent reliability, safety, and environmental standards while scaling in volume to support global EV adoption.
Semiconductor Roles in Automotive
- Power Electronics: SiC/GaN MOSFETs, IGBTs, and drivers for inverters, onboard chargers, DC-DC converters, and battery management systems.
- MCUs & MPUs: Automotive-grade controllers for ADAS, body electronics, braking, steering, and HVAC.
- AI & Compute: Dedicated SoCs, GPUs, and NPUs for perception, sensor fusion, path planning, and infotainment.
- Sensors: Image sensors, radar, LiDAR, ultrasonic, inertial (IMUs), pressure, and thermal sensors for ADAS and autonomy.
- Memory: LPDDR5X, GDDR6, and automotive NOR/NAND for ADAS logging, infotainment, and firmware.
- Connectivity: 5G modems, C-V2X, Wi-Fi/Bluetooth, GNSS, and in-vehicle Ethernet transceivers.
- Analog & Mixed-Signal: Power management ICs (PMICs), sensor interface ASICs, amplifiers, audio, and haptics.
- Security Silicon: Hardware security modules (HSMs), TPM-class devices for OTA updates, encryption, and vehicle-to-cloud trust.
- Displays & Infotainment: OLED/LCD drivers, touch controllers, codecs, and AI-powered graphics SoCs.
