VV5410
®
Mono and Colour Digital Video CMOS Im
The VV5410/VV6410 are multi format digital output imaging
devices based on STMicroelectronics’s unique CMOS
sensor technology. Both sensors require minimal support
circuitry.
VV5410 (monochrome) and VV6410 (colourised) produce
digital video output. The video streams from both devices
contain embedded control data that can be used to enable
frame grabbing applications as well as providing input data
for the external exposure controller.
The pixel array in VV6410 is coated with a Bayer colour
pattern. This colourised sensor can interface to a range of
STMicroelectronics co-processors. A chipset comprising
VV6410 and STV0657 will output 8bit YUV or RGB digital
video. A USB camera can be realised by partnering VV6410
with STV0672. Finally a high quality digital stills camera can
be produced by operating VV6410 with STV0680B-001.
Please contact STMicroelectronics for ordering information
on all of these products.
Both VV5410 and VV6410 are initialised in a power saving
mode and must be enabled via I2C control before they can
produce video. The I2C allows the master coprocessor to
reconfigure the device and control exposure and gain
settings.
USB systems are catered for with an ultra low power, pin
driven, suspend mode.
The on board regulator can supply sufficient current drive to
power external components, (e.g. the video coprocessor).

Introduction
Overview
VV5410/VV6410 is a CIF format CMOS image sensor. The VV5410 sensor is the basic monochrome device
colourised variant. The operation of VV5410 and VV6410 is very similar but any differences will be identified
VV6410 can output digital colourised pixel data at frame and line rates compatible with either NTSC or PAL v
VV5410 and VV6410 contain the same basic video timing modes. Table 2 summarises these video modes.
The various operating modes are detailed in Section 3.
Important:
VV5410 and VV6410’s output video data stream only contains raw data. A master co-processor
generate a video waveform that can be displayed on a VDU

Table 2 : Video Modes
Note: The user can also provide a 24 MHz clock, rather than a 16 MHz clock, for the QCIF-60fps, CIF-25fps
modes, which the sensor then internally divides by 1.5, (see data_format[22]), to give an effective input clock
MHz.
2.2
Exposure Control
VV5410/VV6410 does not include any form of automatic exposure and/or gain control. Thus to produce a co
image the integration period for the pixels, in the sensor array, an exposure control algorithm must be implem
The new exposure values are written to the sensor via the serial interface.
2.3
Digital Interface
The sensor’s offers a very flexible digital interface, the main components of which are listed below:
1. A tri-stateable 5-wire data bus (D[4:0]) for sending both video data and embedded timing references.
2. 4-wire and 8-wire data bus alternatives available. If the 8-wire option is selected then the FST/LST pins
output data information.
3. A data qualification clock, QCK, which can be programmable via the serial interface to behave in a numb
(Tri-stateable).
4. A line start signal, LST (Tri-stateable).
5. A frame start signal, FST (Tri-stateable).
6. OEB tri-states all 5 data bus lines, D[4:0], the qualification clock, QCK, LST, FST and D[7].
7. A 2-wire serial interface (SDA,SCL) for controlling and setting up the device.
