STMicroelectronics (NYSE: STM) today introduced two new image sensors that consume up to 10 times less power, a move targeting the battery-constrained wearables and AR/VR headset market. The VD55G4 and VD65G4 sensors are designed for always-on vision applications, allowing devices to process visual data and AI tasks with minimal energy draw.
"Always‑on vision is becoming essential for the next generation of personal electronics, from smart glasses and AR/VR headsets to intelligent home appliances and medical devices," said Alexandre Balmefrezol, Executive Vice President and General Manager of the Imaging Sub-Group at STMicroelectronics. "With VD55G4 and VD65G4, we are bringing this capability to smaller, lighter products that must run for a long time on a tiny battery."
The new sensors, one monochrome and one color, operate at a resolution of approximately 800x700 pixels and 10 frames per second in their dedicated low-power mode. They are manufactured at ST's facility in Crolles, France, using a 3D-stacked 65nm/40nm process on 300mm wafers. This architecture, combined with a detect-and-wake function, allows the main system processor to remain off until the sensor detects a relevant event, significantly extending battery life.
The launch positions STMicroelectronics to compete more aggressively for the growing embedded vision and edge AI markets, challenging established players in the space. By providing a full ecosystem, including development boards for STM32 and Raspberry Pi platforms and a software development kit, the company aims to speed up adoption among designers of compact, power-sensitive devices. The sensors are currently available to early adopters, with pricing available from ST sales offices.
The VD55G4 and VD65G4 sensors are part of the ST BrightSense portfolio and represent a strategic push into intelligent devices that perform more processing locally. This reduces reliance on cloud computing, lowering both latency and standby power consumption. The small footprint and high energy efficiency make the sensors suitable for a wide range of applications, from glance detection in smart glasses to presence sensing in IoT devices and patient monitoring in medical tech.
The move comes as STMicroelectronics diversifies its offerings, building on recent momentum in its microcontroller and power-management businesses. The company's stock has been trading near its 52-week high, and this product launch could further strengthen its position in high-growth technology sectors. The availability of a full design ecosystem is critical for lowering the barrier to entry for developers and accelerating design wins in a competitive semiconductor market that includes peers like ON Semiconductor (ON) and Microchip Technology (MCHP).
