Global shutter image sensor with I3C and low power consumption
STMicroelectronics has launched an image sensor with a global shutter and low power consumption for AR/VR, personal and industrial robotics, drones, barcodes, biometrics and gestures, and embedded vision and scene recognition.
The ST VD55G1 image sensor is 2.7mm x 2.2mm, and has a native resolution of 800 x 700 pixels. The low power consumption of 1mW 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. It is built with a 2.16um pixel size, high sensitivity, and low crosstalk to minimize the sensor pixel array area on the top die, while maximizing digital-processing capabilities and features on the bottom die.
The 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 and multiple context switches..
“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 global-shutter image sensor also comes with native background removal, which reduces the post-processing workload for the host. The sensor also has an ‘always-on’ 1mW autonomous mode that allows continuous awareness even when the host is turned off, saving power. The system wakes up when a movement or scene change is detected.
ST’s VD55G1 is sampling now, with volume production slated for March 2024. ST partners offer packages and modules embedding the VD55G1 for various use cases and markets.
