VISION & IMAGING  
CUSTOMER DATASHEET CD6500-STV0672S-A: October 1999  
USB VGA Digital Camera Chipset  
VV6500 and STV0672  
The USB camera chipsets from STMicroelectronics are at  
the heart of a variety of products which have proven to be  
highly successful in a demanding marketplace. Supported  
by comprehensive reference designs, technical backup  
and fully-featured software drivers, STMicroelectronics  
offers camera manufacturers the opportunity to benefit from  
rapid time to market with a product of proven quality.  
KEY FEATURES  
Real-time video - up to 15fps VGA (30fps CIF)  
Multiple output image formats supported  
USB 1.1 compliant  
High quality MPEG compression  
Isochronous and bulk USB modes supported  
Automatic black level calibration  
Automatic dark level calibration  
Full VfW and TWAIN driver support  
Integrated voltage regulation  
The VV6500 is a ColorMOSTM digital CMOS sensor that  
delivers outstanding picture quality. This VGA-resolution  
sensor has been created specifically to meet the standards  
required for high quality personal video communications.  
This sensor features automatic black and dark level  
calibration to ensure optimum image quality.  
Minimal BOM for complete USB camera  
Programmable vendor ID  
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,  
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  
minimum impact on image quality. The USB interface  
supports USB isochronous data transfer mode, ensuring  
access to guaranteed bandwidth at all time, irrespective of  
how many peripherals are then added.  
APPLICATIONS  
High quality PC Camera  
Biometric identification  
Toys and games  
Image capture systems
