Infineon Technologies AG has developed the second generation of the REAL3 automotive image sensor IRS2877A, an ISO26262-compliant high-resolution 3D image sensor that comes in a 9 x 9 mm² plastic BGA package and offers a VGA system resolution of 640 x 480 pixels with a tiny image circle of 4 mm. The high resolution of this sensor makes it suitable for camera applications with a wide field of view, such as complete front-row occupant monitoring systems.
REAL3 3D in-cabin sensing cameras capture and process the data needed to ensure a high standard of passive safety through use cases like driver monitoring, occupant detection, and smart airbag systems. The 3D depth data supports the best anti-spoofing capabilities for secure face authentication in order to enable in-car payment or access to private data and cloud services or even to open the car by face-ID. Moreover, ToF cameras also support exterior sensing functions such as secure navigation and collision avoidance.
Key Features
- Time-of-Flight single-chip including illumination control and digital data output
- Patented Suppression of Background Illumination (SBI) circuitry in every pixel for best sunlight robustness
- Spread Spectrum Clock (SSC) to avoid interference with other ToF systems
- Up to 100 MHz VCSEL modulation frequency
- Fast global shutter readout with CSI-2 data interface (2x 1 Gbit)
- Flexible imager operation after each frame: adaptation of frame rate, exposure time or modulation frequency
Development samples of the new 3D image sensor chip IRS2877A are now available and the ISO26262 compliant variant IRS2877AS will be available for series production by the end of 2022.
