STMicroelectronics reveals a new global-shutter image sensor

STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, is enhancing smart computer vision with its latest global-shutter image sensor. The global-shutter sensor technology is particularly useful for capturing distortion-free images when the scene is moving or when near-infrared illumination is used.

 

“Our new global-shutter image sensor provides superb resolution in an extremely small die suitable for use in equipment like smart glasses and AR/VR headsets. It’s also well suited to personal and industrial robotics and smart-home devices. All these applications benefit from the sensor’s high performance, small size, ultra-low power consumption, and optimized cost,” said Alexandre Balmefrezol, Executive Vice President, Imaging Sub-Group General Manager, STMicroelectronics.

 

The sensor is small, measuring just 2.7mm x 2.2mm, and has a native resolution of 800 x 700 pixels. Its low power consumption means it can be used with smaller batteries, and its imaging performance is exceptional, with high contrast and superior image clarity.

The sensor also offers event-like image streaming, making it ideal for eye-tracking and other motion-estimation use cases.

Technical Information
Completing ST’s specialized sensor portfolio, the VD55G1 global-shutter sensor leverages the Company’s advanced process technologies that enable a class-leading 2.16um pixel size, high sensitivity, and low crosstalk. Together, the innovations in silicon process technology and pixel architecture minimize the sensor pixel array area on the top die, while maximizing digital-processing capabilities and features on the bottom die.

 

ST’s advanced pixel technology uses full Deep Trench Isolation (DTI) while optimizing performance through the combination of low Parasitic Light Sensitivity (PLS), high Quantum Efficiency (QE), and a low noise architecture.

 

The device is I3C-controlled for 10x faster communication, and embeds multi auto-exposure, high-framerate operation, flexible tone mapping, multiple context switches, and much more.
