® STV0680B+ VV6410/6411/6500
DUAL-MODE DIGITAL CAMERA CHIPSET
DESCRIPTION
STMicroelectronics Imaging Division has enhanced
the feature set of the STV0680B low cost dual-
mode camera chipset to allow a new line of low cost
cameras or toy products to be brought to the
market.
STANDARD FEATURES
ST have maintained the standard features already
available in the successful STV0680B-001 chipset,
including:
q STV0680B-003 fully backward compatible
with STV0680B-001
q Support for VV6410/6411 (CIF) and VV6500
(VGA) CMOS imaging sensors.
q Support for SDRAM sizes 16MBit (up to 20
CIF images) or 64Mbit (up to 80 CIF or 26
VGA images).
q Low resolution “economy” mode allows for
more images to be stored.
q High frame rate web cam (tethered video)
over USB.
q Automatic anti-flicker exposure control.
q Image up load over RS232 or USB.
q Driver support for Win98/Win2k/WinME and
MacOS 8.6/9.0/9.1.
q Continuous capture while untethered (except
when Flashgun enabled) and downloading to
AVI file format
q Power-saving “stand-by” mode which
maintains memory contents, as well as
generally low power consumption.
q Simple user interface including 2 buttons,
status LCD display, and buzzer.
q Evaluation Kit (EVK) available.
q Software Development Kit (SDK) allows OEM
PC Software applications to be written.
NEW FEATURES AVAILABLE IN STV0680B-003
q Audio record/playback and “Delete Last”
function
q Custom sounds playback (e.g. “Talking” or
“Musical” camera)
q Flashgun support
q Quick Power Down (by holding Mode
Button).
Audio Record And Playback
The enhanced features included in STV0680B-003
allow audio memos to be recorded, stored in
SDRAM, and uploaded to the PC over USB or
RS232, to be played back using an OEM software
application developed using the SDK
With the addition of playback hardware, recorded
audio sounds can also be played back on the
camera, and it is possible to download a set of
custom sounds from the PC to allow (e.g.) shutter
“Click-Whirr”, or for a “Talking Camera”. This has
limitless possibilities for OEM language
customising or licensing.
Flashgun Support and “Delete Last” Function
STV0680B-003 includes flashgun support for an
OEM flashgun module. An additional user interface
function is available in STV0680B-003 which allows
the user to delete the last image, continuous clip or
audio memo which was captured or recorded.
Evaluation Kit and Reference Design
Evaluation kits are available for both standard
features and enhanced STV0680B-003 features.
Precise design guidelines are available from ST as
a separate STV0680B Reference design manual
(see Chapter 12).
Note: Simultaneous audio record and
continuous video capture is not possible.

STV0680B + VV6444/6410/6500
Detailed features
3 A CIF camera with STV0680B-001 and 64Mbit SDRAM can store up to 320 images by using QCIF
mode. Where >99 images are still available, the LCD display will remain at 99. Where (no. of
images available) <99, the LCD display will show the number of images available, as is the case
with all other modes.
2.1.1 VV6444
VV6444 is a CIF resolution, 5V CMOS imaging sensor and has been superseded by VV6410/6411.
2.1.2
VV6410
VV6410 is a CIF resolution, 3.3V CMOS imaging sensor. A brief specification is shown in Chapter 6.
A dual design to support VV6444 and VV6410/6411 is not possible, since VV6410/6411 is a 3v3
sensor. A single footprint for VV6410/6411 and VV6500 is not possible since the package types
differ, however, the same support circuit is used.
For IR filter design, the best choice filter follows the GS0034 dielectric stack filter specification,
which is available from ST. An alternative, although not optimal filter, would be Schott S8612 doped
glass, also sold as CM500.
2.1.3
VV6411
VV6411 is a CIF resolution, 3.3V CMOS imaging sensor. A brief specification is shown in Chapter 6.
The functionality, pixel size, resolution and support circuit are identical to VV6410, however, the
colour filter material is slightly different, and the package type and pinout may differ to VV6410.
Contact ST for further details.
A single footprint to support VV6411 and VV6500 is not possible because of the package difference.
A single footprint to support VV6410 and VV6411 may be possible, dependant on the final package
for VV6411.
2.1.4
VV6500
VV6500 is a VGA resolution, 3.3V CMOS imaging sensor. A brief specification is shown in
Chapter 6
A dual design to support VV6444 and VV6500 is not possible, since VV6500 is a 3v3 sensor. A
single footprint for VV6410/6411 and VV6500 is not possible since the package types differ,
however, the same support circuit is used. See Chapter 6.
For IR filter design, the best choice filter follows the GS0034 dielectric stack filter specification,
which is available from ST. An alternative, although not optimal filter, would be Schott S8612 doped
glass, also sold as CM500.
2.1.5 SDRAM
This is covered in more details in Chapter 4.
2.2 User interface
The user interface supported by STV0680B comprises of user controls, buzzer sounds or
customised audio sounds and visual displays.
2.2.1
Push buttons
The following are the functions which are supported by the chipset. These functions are achievable
with no more than 2 push buttons.
