Supported offers camera manufacturers the opportunity to benefit from rapid time to market with a product of proven quality. The VV6500 is a ColorMOSTM digital CMOS sensor that delivers outstanding picture quality. This VGA-resolution This sensor features automatic black and dark level calibration to ensure optimum image quality. The STV0672 (CPIA2) co-processor receives image data from the sensor, that is processed, compressed and passed to the USB port. It incorporates a digital video processor engine to perform automatic exposure, automatic gain control and automatic white balance, APPLICATIONS * High quality PC Camera * Biometric identification * Toys and games * Image capture systems together with colour matrixing, gamma correction, aperture correction, automatic defect correction and noise cancellation logic. This data is passed to the proprietary video compression that delivers high frame rates with SPECIFICATIONS minimum impact on image quality. The USB interface supports USB isochronous data transfer mode, ensuring Pixel resolution 640 x 480 (VGA) access to guaranteed bandwidth at all time, irrespective of Array size 1/3" lens format Exposure control Automatic (>1000000:1) Gain control Automatic (to +24dB) Signal/Noise ratio 57dB Supply voltage 4.1v-5.25v DC ( internally regulated) USB Compatibility USB Specification V1.1 Meets full power management requirements with no external components Supply current 100mA approximately Operating temperature (ambient) (for extended temp. info please contact STMicroelectronics) how many peripherals are then added. The chipset is backed by a fully-featured driver which provides a host of user-definable settings for optimum camera setup. The user interface supports a degree of customisation. STMicroelectronics offers a range of support services to guarantee product quality, including test specifications and test software.

SUPPORT DOCUMENTATION EEPROM STV0672 STMicroelectronics have produced comprehensive Reference Design documentation for design-in of this chipset. The reference design includes schematics, Support EEPROM to initialise STV0672 (optional) gerbers, BOM and documentation to allow the implementation of a full production-ready camera. USB data packets back to PC host Contact STMicroelectronics for further details. ORDERING DETAILS Part Number Description VV6500-C048 VGA resolution CMOS sensor, 48LCC package STV0672-001 CPiA2 coprocessor STV-USB/VGA-E01 USB chipset This chipset allows the implementation of a high quality PC camera with a minimum of external components. The support EEPROM is optionally populated if a custom USB enumeration sequence is required. The STV0672 can perform inter-frame MPEG compression to a ratio of approximately 10:1. The companion ASIC can now also perform on the fly defect correction . No transceivers are required to interface to the USB bus, and no external components are required to meet the power management requirements of the USB specification. VV6500 has an ultra low power mode where the sensor will consume less than 50uA.
