Foreword

This manual provides technical information on the STMicroelectronics STV0674 Evaluation Kit,
designed and manufactured by STMicroelectronics Ltd., 33 Pinkhill, Edinburgh, United Kingdom.
The content includes detailed system description, specifications, installation and operating
instructions.

Electromagnetic Compatibility Notice

This equipment generates and can radiate radio frequency energy which may cause harmful
interference to radio communications.

If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of these measures:

● Re-orientate or relocate the receiving antenna,

● Relocate the equipment with respect to the receiver,

● Plug the equipment into a different outlet so that equipment and receiver are on different

branch circuits.

This equipment is f or demonstration and eval uation purposes only. It has no intrinsic function and
can therefore be cons ide red as a "compone nt" or " sub-assembly". Howev er, it is not intended to be
used either in part or whole to form another product with an intrinsic function, therefore does not
comply with FCC rules regarding Electromagnetic Compatibi li ty.

While ev ery eff ort has been made to k eep the in formation contained within current and accurat e as
of the date of publication, no guarantee is given or implied that the document is error-free or that it
is accurate with regard to any specificat ion. STMicroelectronics reserves the right to mak e changes,
at any time, for the purpose of system improvement.

A sample of the camera described in this manual has been passed through USB compliance, which
would indicate that it is possible to follow the refer ence desi gn guidelines closely and achieve
compliance in an OEM design. However, such compliance tests are the responsibility of the OEM.
