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.

The VV6500 and STV0672 are part of a comprehensive

range of image sensing and co-processor products from

STMicroelectronics

for

applications

including

videoconferencing, digital stills cameras, toys, security

and biometrics. Visit the VISION & IMAGING web site at

www.vvl.co.uk for more information.

STMicroelectronics

have

produced

comprehensive

Reference Design documentation for design-in of this

chipset. The reference design includes schematics,

gerbers,

BOM

and

documentation

to

allow

the

implementation of a full production-ready camera.

Contact STMicroelectronics for further details.

ABOUT VISION & IMAGING TECHNOLOGY

SUPPORT DOCUMENTATION

ORDERING DETAILS

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.
