Description
This image sensor based on STMicroelectronics CMOS technology is Bayer colorised. The sensor provides a raw digital video output which also contains embedded codes to facilitate external synchronisation. The sensor interfaces to a range of STMicroelectronics companion processors for applications such as USB webcams and digital stills cameras. An I2C interface allows an external processor to configure the device and control exposure and gain settings. A low-power pin-driven suspend mode simplifies USB-based designs. On board voltage regulators operate from a 5V USB supply and generate 3V3 and 1V8 power supplies for external processors.
