Overview
The ST VD55G4 is an ultracompact, ultralow-power global-shutter CMOS image sensor from the ST BrightSense portfolio. It pairs a 0.56 MP (804 x 704) array built on the industry's first 2.16 µm global-shutter pixel with BSI, CDTI and 3D-stacking to fit a 2.73 x 2.16 mm die into the most size-constrained devices.
A dedicated always-on mode consumes as little as 0.9 mW and watches for scene changes, waking the host processor only when needed — enabling all-day, battery-powered or energy-harvesting vision systems. The monochrome variant (visible-to-NIR) is designed for machine-perception and presence/gesture workloads.
Key Benefits
VD55G4 — smallest global-shutter pixel class. Up to 10x lower power than conventional global-shutter sensors, microcontroller-compatible MIPI CSI-2/SPI/I3C interface, and on-sensor statistics for automatic white balance and exposure.
Applications
Always-on presence and gesture detection, smart glasses and XR headsets, wearables, personal electronics, barcode/OCR and embedded machine vision where board space and battery life are critical.
