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.

EXAMPLE APPLICATIONS
ABOUT VISION & IMAGING TECHNOLOGY
Our unique CMOS technology enables integration of the
sensor array and associated support circuitry on a single
VLSI microchip. CMOS sensors are compact, highly
integrated devices that require reduced power
consumption over traditional CCD devices while offering
equivalent image quality.

Description
VV6500-C048
VGA resolution CMOS sensor,
48LCC package
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.
STV0672-001
CPiA2 coprocessor
USB chipset
STV-USB/VGA-E01
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 .
