Introduction
1.1
Digital camera chipset
This document describes the features and functionality of a CMOS chipset, comprising an
STMicroelectronics (ST) CIF or VGA resolution sensor and an STV0680B companion processor
(DCA1), as well as outlining what peripheral components are required/supported in order to
complete a camera using the chipset. Such a camera is particularly suited to dual-mode digital stills
or toy applications.
In stills mode, the camera stores raw image data in memory. The camera carries out no colour
processing, ensuring its simplicity and low cost. Subsequent download of raw data to a PC or
Macintosh for processing is done through an RS232 or USB interface, through demo software, a
TWAIN driver, or OEM custom application. The license to use the colour algorithm (embedded in
the PC or Mac driver software) is included in the price of the chipset.
A video option is provided, when tethered through USB, which can allow for Video for Windows
applications, and ‘video clips’ can be recorded while untethered by continuously capturing images
while in ‘Continuous’ mode, then downloaded to the PC for playback, using software to create an
AVI file.
Using STV0680B-003, the firmware also includes the capability to trigger a flashgun module
through a two wire interface (enable input and trigger output), and the capability to record audio
sounds into the SDRAM, for subsequent upload to the PC, or to replay audio sounds which have
either been recorded on the camera or dowloaded from the PC (stored on the PC as.WAV files).
Precise design guidelines are available from ST as a reference design (see Section 4). A software
development kit (SDK) for PC is available from ST, to interface to the camera and provide the basis
for developing a custom software application for stills and/or video, which includes colour
processing software as object code.

Version 3.4
STV0680B + VV6444/6410/6500
Introduction
1.4.6 User features on PC software (STV0680B-003)
All PC software written for a STV0680B-001 camera will function with a STV0680B-003 camera
which is only used to take still images/video.
The SDK (version 2.90 or later) allows for:
● the OEM to write a custom application for uploading sound memos, based on the example
LCDC demo software.
● the OEM to write a custom application for downloading custom sounds to the camera, based
on the example CustomSound software.
1.4.7 Power management features and USB compliance
● Retention of pictures, recorded sounds, and downloaded custom sounds with extremely low
power operation, which appears to the user as if the camera is “switched off”.
● Auto power-off after 30sec with no user activity
● Operates from 4.5-6V battery, although system voltage is 5V or 3.3V, dependant on sensor.
● Low battery detection
● Dependant on hardware configuration, switch-over to USB power supply is supported, to allow
the device to operate with low batteries or without batteries, when connected to USB.
● Full USB compliance requirements are listed in the USB specification, however, in a camera
designed using this chipset, the following must at least be included: (a) an SDRAM with
sufficiently low self-refresh current, (b) USB inrush protection circuitry, and (c) (in the case of
VV6444 only) a switched 5V sensor supply is used, to maintain sufficient supply voltage to the
5V sensor. See Section 4 for further details.
1.4.8 General features

Detailed features
2.1
Sensor type and image formats
The sensor type is auto-detected by STV0680B, which ensures that the correct sensor timing is
enabled, and the correct image resolutions are enabled, as shown in Table 3.
For stills photography, ‘High’ or ‘Low’ resolution mode can be selected, to give CIF or QCIF pictures
from a CIF sensor, and VGA or QVGA from a VGA sensor (see Table 3). Reduced resolution allows
for storage of more images. Images captured in both ‘High’ and ‘Low’ resolution can be stored in
camera memory at the same time. Therefore there is no need for images stored in memory to be
cleared before changing image resolution.
Where USB is connected, the host PC software (through a Video for Windows driver) can activate
tethered video mode, regardless of the user inputs to the camera buttons. In this case, the image
resolution is controlled by the PC driver.
Note: When tethered VfW video (PC) or Quicktime driver (Mac) is activated, all images or recorded
sounds or video clips will be deleted from the camera SDRAM. A software solution is available
(“Camera control”, as part of the SDK for PC, and “Plug’n Save” for Mac) which can monitor
whether a camera is connected and will warn the user if activating the VfW driver will cause SDRAM
contents to be deleted.

2 On a camera using STV0680B-003, the number of images which can be stored is reduced if Audio
sounds have been recorded on the camera or if custom sounds have been downloaded from the
PC to the camera. The reduction of capacity depends on the length of audio clip, but a rough guide
is that if 1 CIF image uses the same amount of SDRAM as 10sec of audio, and one VGA image
uses the same amount of SDRAM as 30 sec. of audio.

Version 3.4
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.

Mode button (Wake-up/Switch between modes): This button allows the user (1.1) to wake the
camera up from standby mode when the camera is to be used for taking pictures, or (1.2) to
switch between modes of operation shown in Chapter 3.
Shutter button (Shutter/confirm action): This button allows the user to take a picture or confirm
an action, as shown in Chapter 3
The modes of operation are described in Chapter 3.
It may also be desirable to include an on-off slider switch. This has advantages and disadvantages,
and its exact function is discussed further in the reference design available from ST.
Where a flashgun module is included in the camera, it will be necessary to include a flash on/flash
off push button or slider switch, dependant on the exact flashgun module design. possible
implementations are discussed in a separate application note AN1312 regarding flashgun
implementation, available from ST.
2.2.2 LED indicator
An LED display camera status, i.e. to show that the camera is not in Standby/PC suspend mode.
2.2.3 Picture counter using 2 x 7 segment display
STV0680B stores a picture counter value, which shows how many images can still be captured.
STV0680B supports a 2x7 segment LCD panel. In ‘Snapshot’ mode and continuous capture mode,
this LCD panel displays the number of pictures still available, which is useful to identify when the
user is approaching the maximum number of images which can be stored (see Table 3). It is
possible to clear the images stored in memory, in order to continue taking pictures. In other modes,
this LCD panel shows displays a 2-character code, which helps the user to navigate around the
modes.
Note: A CIF camera with STV0680B 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.
For suitable numeric LCD panel types, see Section 4.8.
2.2.4 Piezo buzzer
An on-chip Pulse Width Modulator (PWM) on STV0680B is used to generate buzzer sounds to
signal certain events. The following are typical of the type of events which are indicated by the
buzzer, and each has its own distinctive sound:
1
Camera has been ‘Woken up’ from standby mode (either by the user pressing a button, by re-
connecting the power source, or by connecting a USB/RS232 connection).
2
Camera has been ‘gone to sleep’ i.e. moved into standby mode. Pictures are retained in
memory.
3

Table 4 : List of custom sound functions
Note: 1 Where a given function has a sound associated with it stored in SDRAM, the piezo buzzer does not
give any beeps for that function. Not all functions need to have custom sounds associated with
them, this is the choice of the user or OEM.
2 A demonstration PC application “CustomSounds” is available from ST, however this is not intended
for end-users. Source code is available which allows the EOM to build their own PC application
using the SDK.
2.3
Battery level detect and USB auto-switch
An on-chip battery level detector on STV0680B detects when the battery voltage falls below a
threshold. This threshold is determined by the designer, dependant on the perception of what
remains as ‘acceptable’ image quality as the battery voltage falls. The chosen threshold level is
determined by a resistor value, as shown in Chapter 6 Where no USB has been detected, the LCD
display flashes, which indicates that the battery is low. Where a USB connection has been detected,
the camera sources power from USB, if certain additional hardware is fitted.
Note: It may be a requirement of certain USB compliance tests that such additional hardware is included
in the camera design, in order to enable the camera to switch to supply from USB and hence report
back to the PC while connected to the USB bus without a battery.
2.4
Audio record and playback
2.4.1 Record
A camera which includes STV0680B-003 and a microphone, comparator and other periphery (also
utilizing the sensor pre-amplifier) can be used to record sounds which are stored in the same way
as images. STV0680B-003 will auto-detect the presence of Audio record hardware and include
Version 3.4
13/63
Detailed features
STV0680B + VV6444/6410/6500
audio record and “delete last” functions into the user interface. The audio sample rate is 11.025kHz,
and the signal is digitised using a successive approximation A-D converter with 8 bits resolution.
The SDRAM stores 1 second of Audio recording per 11k Bytes of memory.
2.4.2 Playback
A camera which includes STV0680B-003 and an amplifier, speaker/headphone socket, and other
periphery, can be used to playback sounds which were either recorded on the camera or
downloaded from the PC.
The quality of Audio playback is largely dependant on the type of speaker used, and on the correct
mounting of the speaker in the camera plastics.
2.5
PC interface options and software support
Either USB Interface (full speed 12Mbit/sec. max.) or RS232 interface (115.2Kbaud) is supported
by the chipset, with driver software available from ST for both. The interface type is auto-detected
by the chipset. PC software can be one of the following:
1
Simple image upload demonstration software supplied by ST, allowing uploading of stills or
‘continuous’ images. This software should not be supplied as an end-user product.
2
3
4
TWAIN driver to suit all TWAIN compatible imaging applications
Video for Windows driver for tethered video mode (USB only)
Custom end-user software developed by OEM using SDK (for SDK availability, contact ST).
The SDK is supplied by ST as a 32-bit DLL format, running on Windows 98, and accessed
through a documented software interface. This provides the basis for developing a custom
software application for uploading stills and/or video.
2.5.1 USB
Complete images (displayed as either thumbnails or in full resolution), or the entire SDRAM
contents (e.g. for uploading continuously captured image sequences, recorded using ‘Continuous
Capture’ mode) can be downloaded through USB, and USB connection also allows for tethered
video mode to be activated by the USB driver.
Thumbnail image download is extremely fast for the entire memory contents in the camera. Once a
picture is selected for download, full image download takes approximately 0.15 seconds per image
for a CIF image (0.6 seconds for a VGA image), plus post processing time per image.
For USB interface details, see Section 4.4.
Note: Actual USB download and post processing time also depends on PC performance and USB bus
loading
2.5.2 RS232
Thumbnails of images, complete stored images, or the entire SDRAM contents can be downloaded
through RS232, but tethered video is not supported.
Once a picture is selected for download, full image download takes approximately 10 seconds per
image for a CIF image (around 30 seconds for a VGA image), plus post processing time per image
(of the order of 1 second approximately).
For RS232 interface details, see Section 4.5.
Note: Actual post processing time after RS232 download also depends on PC performance

2.6
Anti-flicker exposure and gain control
2.6.1 General
The chipset operates automatic exposure and gain control for either 50Hz or 60Hz mains-driven
indoor lighting, using the same 12MHz crystal. This improves picture quality by selecting a set of
exposure values which minimise ‘flicker’ effects. Detection of the mains frequency is dependant on
the status of the GPIO3 pin, which can be achieved by population of a PCB link at a late stage in
production, once the country of destination is known, without the need to change the crystal
frequency.
The auto exposure and gain algorithm is always enabled during Snapshot’/self-timer/continuous
mode. When the shutter button is pressed in ‘Snapshot’ mode, the chipset captures an image if the
exposure and gain value has reached a suitable value for the current scene. If the light detected has
suddenly changed, the camera may emit an audible tone to indicate that more time is required to
reach the correct exposure target. In ‘Snapshot’ mode the chipset only captures the image data if
sufficient light is present in the image. In continuous capture mode, the chipset captures images
regardless of whether enough light is present.
The exposure control algorithm in STV0680B chooses exposure values which minimise “flicker”
effects from occurring under fluorescent lighting. STV0680B can only prevent flicker in lighting
powered by 50Hz or 60Hz electricity supply, but automatic detection of the flicker frequency is not
possible. Hence choosing the correct anti-flicker setting is important, in order to prevent dark stripes
form appearing across the image, and this selection must be done in hardware.
Flicker setting not correct
Flicker setting correct
Figure 2 : Illustration of flicker problem
2.6.2 Flashgun exposure
Where STV0680B-003 and a flashgun module are included in the camera, and the flashgun enable
signal is HIGH, the exposure mode will operate in a different manner. The CMOS sensor
progressive scan readout requires that the sensor is set to maximum exposure so that all lines are
being exposed at a certain point in time.
The “window” within which the flashgun needs to fire in order to correctly expose all sensor lines is
of the order of a few 100µsec (contact ST for more precise details), therefore the flashgun module
design should have reached maximum light output within this period after the falling edge of the
flash trigger output from STV0680B-003.
Possible flashgun implementations, regarding hardware interface, charge sensing, and flash
energy required are discussed in a separate application note AN1312 regarding flashgun
implementation, available from ST.

Description of modes
Note that certain modes are only available using STV0680B-003, and with appropriate hardware
fitted on the camera.
3.3.1 Standby mode (untethered) and Wake-up
On power-up, or wake-up from untethered standby mode, (i.e. by pressing the Mode button), the
camera will beep twice. The LCD will briefly indicate the camera resolution either ‘Hr.’ for high
resolution (80 CIF or 26 VGA images - using 64Mbit memory) or ‘Lr’ for low resolution (322 QCIF or
107 VGA images - using 64Mbit memory) and then display the number of pictures which may be
taken. Please note that in Low Resolution Mode, although there can be up to 322 images available,
the LCD counter will only go up to 99, it will continue reporting 99 until there are less than 99 images
left.
The camera will go back to standby mode either after 30 seconds of inactivity, LED1 will turn off and
the LCD will go blank. This can also be done (STV0680B-003 only) by pressing the mode switch for
more than 2 seconds.
3.3.2 Normal mode
Pressing the shutter button will take a picture. The camera will beep. A high pitched beep indicates
that the picture was taken successfully and the counter will decrement (if there are less than 99
images left to take). A low beep indicates insufficient light to take a picture. A series of beeps
indicates that the camera is full.
Version 3.4
17/63
Camera modes of operation
STV0680B + VV6444/6410/6500
Stored pictures may be uploaded to a PC at any time, whether or not the camera is full. Plugging the
USB connector into the camera will cause it to reset and issue a double beep but all stored pictures
will remain. When the USB connector is unplugged the camera will go to sleep. When connected to
the PC the camera may still be used in the normal way.
Note: With the flashgun enabled (STV0680B-003 only) the camera will always take a picture,
whether or not there is sufficient light.
3.3.3 Audio record - Ar
This mode is available on STV0680B-003 only, with audio record hardware fitted.
Pressing the shutter button within 5 seconds will cause the camera to start recording for as long as
the shutter button is pressed down. If the shutter button is not pressed within 5 seconds the camera
will revert to normal picture taking mode. Whilst recording, the LCD display flashes ‘Ar’. If the
recording stops because the memory is full, the ‘memory full’ audio tone is sounded and the display
will stop flashing and display ‘00’. The audio data is digitised and stored in SDRAM.
3.3.4 Audio Playback - AP
This mode is available on STV0680B-003 only, with audio playback hardware fitted.
Pressing the shutter button within 5 seconds will cause the camera to play back the most recent
audio recording. If the shutter button is not pressed within 5 seconds the camera will revert to
normal picture taking mode. Whilst playing, the LCD display flashes ‘AP’.
Once in Audio Playback mode, repeated presses of the shutter button will step the camera through
each of the audio recordings in the camera (most recent first). Keeping the shutter button pressed
down will also cycle through the audio recordings. Pressing the mode button during playback will
stop the audio clip.
Note: Minimum audio recording length is set to 0.5 seconds.
3.3.5 Delete last object - dA/dP/dC
This mode is available on STV0680B-003 only, with audio record hardware fitted.
If the last object captured was an audio recording 'dA' (delete audio) will be displayed, if the last
object was an image, then 'dP' (delete picture) will be displayed, or, if the last object was part of a
continuous capture sequence, then 'dC' (delete continuous) will be displayed. If the camera is
empty, the mode will be suppressed. The mode works in the same way as ‘CL’ (Clear All), i.e. once
the mode is selected, pressing the shutter button once will cause the camera to beep and ‘dA’, ‘dP’
or ‘dC’ to start flashing. Pressing the shutter button again within 5 seconds will delete the last audio
clip, picture or continuous capture sequence.

Version 3.4
STV0680B + VV6444/6410/6500
3.3.6 Continuous mode - Ct
Camera modes of operation
Pressing the shutter button within 5 seconds will cause the camera to start taking pictures for as
long as the shutter button is pressed down (and the camera is not full). If the shutter button is not
pressed within 5 seconds the camera will revert to normal picture taking mode.
Note: 1 During continuous mode the camera will allow pictures to be taken regardless of the available light,
which could result in insufficient exposure.
2 In continuous mode, only every alternate field is grabbed hence capture rate is halved. E.g. 12.5fps
CIF and 7.5fps VGA
3 On STV0680B-003, Continuous Mode is suppressed when the FlashGun enable signal (GPIO2) is
high.
3.3.7 Self timer - St
Pressing the shutter button will now start a 10-second self-timer. The camera will issue a short beep
every second and then a longer beep. A further beep will then indicate that the picture has been
taken (high beep - picture successful, low beep - insufficient light, picture not taken). The self-timer
mode can not be selected when the camera is full. The self-timer countdown cannot be stopped
once it has started.
3.3.8 Clearing the camera memory - CL
Pressing the shutter button once will cause the camera to beep and the ‘CL’ to start flashing.
Pressing the shutter button again within 5 seconds will clear all the images/audio clips in the
camera and reset the counter.
3.3.9 Changing picture resolution - Hr/Lr
The resolution option is displayed, either Hr. to change to high-resolution mode (if currently in low-
resolution mode) or Lr to change to low-resolution (if currently in high-resolution mode). Press the
shutter button within 5 seconds of selecting the resolution option, the camera will beep and the
display will reset indicating the number of pictures available in the new mode. The picture resolution
can be changed at any time, i.e. the camera can store both high and low resolution images.

STV0680B hardware interfaces
4.1
STV0680B pinout
The STV0680B pinout has been carefully developed to minimise the physical size of the support
printed circuit board by facilitating placement of and electrical routing to peripheral support
components such as the SDRAM. The complete pinout and listing is shown in Chapter 6
4.2
4.3
Sensor interface
STV0680B uses a standard ST digital interface from the sensor, and the sensor clock input is
provided by an output from STV0680B. Designing a camera using this chipset should design as
close as possible to the reference design (Chapter 6), in which case the chipset can be regarded as
a functional ‘black box’, and no further details regarding the STV0680B-sensor interface are
required.
Memory interface
STV0680B is designed to interface to an external 16Mbit or 64Mbit SDRAM (see Table 3). The
SDRAM device must have a 16 bit wide data bus and operate from a 3.3V supply. Two sizes of
SDRAM memory are supported by STV0680B, 16MBits (1M x 16 bits wide) or 64MBits (4M x 16
bits wide), the memory size is auto-detected by STV0680B. STV0680B clocks the SDRAM at
6MHz, typically this is well below the figures offered by most manufacturers’ devices. Devices which
are PC66 and/or PC100 compliant are preferred. For interface wiring, see Chapter 6
4.3.1 SDRAM current consumption
For maximum system battery life while no pictures are being taken, and to assist in meeting
requirements for USB compliance, an SDRAM should be chosen with the lowest possible self
refresh current specification. For suggested SDRAM part numbers, see Chapter 6
In addition, the USB suspend mode current specification requires that the camera will consume no
greater than 300µA when un-tethered. Meeting this specification, which is included in the
requirements for USB compliance, assumes an SDRAM with up to approximately 250µA self-
refresh current, based on a current consumption of approximately 50µA for STV0680B+support
circuit.
4.3.2 SDRAM interface timing requirements
The following timing diagrams should be referred to when selecting SDRAM other than those
recommended in Chapter 6

4.3.3 SDRAM refresh period
The SDRAM refresh period from STV0680B is guaranteed to be no greater than 15.6µS during
‘Snapshot’/self-timer/continuous/tethered video modes of operation (i.e. not standby mode). In
standby mode, the SDRAM is set to self-refresh, therefore no refresh from STV0680B takes place.
4.3.4 SDRAM initialisation period
The SDRAM initialisation period is currently set to 981µS in STV0680B.
4.4
USB interface
STV0680B includes a USB Version 1.1 compliant Universal Serial Bus Interface, including a
transceiver. This allows direct connection from STV0680B to a USB connector with minimal
additional hardware (i.e. a small number of passive discretes) - see Chapter 6
The USB interface interfaces the STV0680B to the USB at full speed 12MHz data rate. Some of the
features are:
● Compliant with USB protocol revision 1.1.
● USB protocol handling.
● USB device state handling.
● Clock and data recovery from USB.
● Bit stripping and bit stuffing functions.
● CRC5 checking, CRC16 generation and checking.
● Serial to parallel conversion.
● Single bulk end point.
USB drivers are supplied by ST. For USB timing information, please refer to the USB specification

STV0680B hardware interfaces
4.5
UART module for RS232 interface
The UART module on STV0680B provides a 115200 baud full duplex interface to an external Host.
4.5.1 RS232 physical interface
STV0680B does not support direct connection to a serial link. Physical line driver circuitry is
required, e.g. using a standard RS232 transceiver chip, or by using a small number of low cost
discretes (as shown in Chapter 6). The schematics shown assume a 3 core cable with a length of
no greater than 2m. Unscreened cable can be used, a suitable low cost connector is a 3.5mm audio
jack plugs/sockets.
4.5.2 UART module overview
Receiving data
The UART module in STV0680B receives serial data through the RXD pin. Data reception is
initiated by a 1-to-0 transition on RXD, and the received data is sampled every 8.66µS.
If the RXD input is not 0 when the incoming data is first sampled, the UART module goes back to
look for another 1-to-0 transition. This is to provide rejection of false start bits. If the start bit proves
valid, reception of the rest of the frame will proceed.
Transmitting data
When a transmission is activated by STV0680B, the contents of an internal transmit shift register
are shifted onto the TXD pin, every 8.66µS.
The UART operates at 12MHz, which is not an integer multiple of 115200, so the actual baud rate is
115232 +/- 0.3%, which is well within the requirements of a typical 16x oversampling UART, which
can tolerate a 3.75% error in baud rate.
4.6
Power management and battery type
STV0680B and the SDRAM require a 3.3V supply. Where a VV6410/6411 or VV6500 (3.3v) sensor
is used, a single voltage regulator can be used to regulate the supply for all three components from
the battery, or the sensor on-board VReg can be used. Where a VV6444 is used, the sensor
requires a 5V supply, hence a DC-DC converter is recommended to provide enough voltage when
the camera is powered from the USB bus. These are explained more fully in the reference design.
4.6.1 Power switching to USB
Included in the USB compliance requirements, is the ability of the camera to report to the PC when
connected to the USB bus, whether or not there is a fresh battery in the camera. This means that
power sourcing from USB is required, which also saves on battery life while the camera is used in
USB tethered video mode. In order to allow switching from battery to USB power, some additional
hardware is required (see also Chapter 6):
● The USBDETECT input to STV0680B is used to detect that a USB power supply is connected
● If the USB is detected, additional hardware is used to switch off the battery
● An inrush protection circuit can protect the USB bus from current draw in the case of a low
battery/battery not fitted. This may be necessary to comply with the USB specification.
For precise USB compliance requirements, please consult the USB specification version 1.1
4.6.2 Switched sensor supply
Dependant on the hardware implementation, the SENSPWR output from STV0680B can be used to
power off completely the sensor during Standby mode (in the case of VV6444) or put the sensor
Version 3.4

STV0680B hardware interfaces
STV0680B + VV6444/6410/6500
into Suspend mode (in the case of VV6410/6411/6500). This has a significant improvement on
battery life.
4.6.3 Battery type
This is hardware dependant. The schematics referred to in Chapter 6 assume either three or four
1.5V cells.
4.7
4.8
Quartz crystal
Regardless of the sensor type or anti-flicker requirements, the sensor + STV0680B chipset
operates from a single 12MHz fundamental quartz crystal. For specification requirements, see
Table 13. STV0680B includes an on-chip low jitter PLL, for PLL characteristics, see Table 12.
Numeric LCD interface
STV0680B supports a 2-digit LCD panel only, for alpha-numeric display.
4.8.1 LCD types
STV0680B connects to a non multiplexed, direct drive LCD with 2 x 7 segments. Many LCD types
are compatible with this interface. The LCD refresh frequency is 34.7Hz.
4.8.2 LCD interface pinout
The convention for segment numbering is as follows: ’0’ connects to segment ’a’, ’1’ connects to
segment ’b’, and so on, where a to g are standard for all 7-segment displays, as well as an LCD
common output, giving fifteen signals in total.
4.9
Switches and LED’s
The GPIO lines on STV0680B have pre-defined functions as follows, see Section 2.2 for user
interface functionality, and Chapter 6 for precise hardware implementation
4.9.1 MODE push button and SHUTTER push button: GPIO0 and GPIO1
Both push button inputs have internal de-bounce circuits, reducing the amount of hardware required
externally. It is recommended that labelling is used on the camera casing to help the user
understand the functioning of the 2-button interface.
4.9.2 Input to select between 50 and 60Hz flicker frequency: GPIO3
This allows for factory setting of the anti-flicker frequency, dependant on the final country of
destination. See also Section 2.6. The polarity of this selection is detailed in the reference design
(see Chapter 6).
4.9.3 LED indicator output: GPIO5
The LED output has an 8mA current sinking capability.
4.9.4 Other pins: GPIO2, 4, 6, 7
With STV0680B-001, these pins are un-used and should be tied to GND.

from the sensor microphone preamplifier), and the resultant high or low signal from the comparator
is read at GPIO4. The sampling frequency is 11kHz, and the successive approximation is done at 8
bits resolution per sample. It is not possible to speed up the sampling frequency due to the limitation
of STV0680B firmware speed.
An actual hardware implementation is given in the audio application note AN1310.
4.9.6 Audio playback hardware interface (STV0680B-003 only)
The firmware outputs the desired signal level through the DAC output, which is amplified to the
speaker or headphone socket. GPIO6 is used to switch off the amplifier during periods of audio
recording, to prevent the successive approximation waveform from being heard during periods of
recording, and to reduce the power consumption and unwanted crackle through the speaker.
An actual hardware implementation is given in the audio application note AN1310.
4.10 Flashgun hardware interface (STV0680B-003 only)
STV0680B-003 will revert to flashgun exposure when it detects GPIO2 is high. Ideally the hardware
should combine the two factors of (a) user intention (e.g. user switches on flashgun) and (b) charge
sensing (i.e. flash is charged up and ready to fire).
These two factors (a) and (b) are independent, since there may be a delay of several seconds
between switching on the flashgun charger, and the flashgun being able to fire. To revert to flashgun
exposure before the flashgun is completely charged up would cause very bad pictures to be taken
in low light conditions because there is no “low light” threshold when flashgun exposure is enabled,
since the camera expects a flash to fire. A suggested flashgun hardware interface is given in the
flashgun application note AN1312.
When flashgun exposure is enabled and the shutter button is pressed, a picture will be taken and
the flash trigger pin GPIO7 will be pulsed low at the correct point in time so that all lines of the
CMOS imager are exposed.
4.11 IR filter
An Infra-Red Blocking Filter is required to achieve correct colour response. The exact specification
for the IR filter characteristics are given in the reference design manual.

General features
The chipset is a dual-mode camera, i.e. stills and video, and is supported by a range of
demonstration software, standard drivers, and software development options.
Driver software is available to support both USB and RS232 interface including standard TWAIN
and video for Windows drivers (VfW through USB only) for Win98/Win2k/WinME. Quicktime drivers
and a Photoshop stills plug in for MacOS 8.6/9.0/9.1 are also supported.
Example software applications (PC only) are provided to create .AVI video files from untethered
continuous capture of images (AVICreator), to upload still images and recorded sounds
(LCDCdemo) and to download .WAV files from the PC to the camera (CustomSound). In each case,
PC source code is provided to assist in OEM software development using the SDK.
ST colour processing and defect detection/correction software runs on the host and is supplied
under licence agreement, as part of all host software/drivers/SDK.
5.1.1 Still image upload
This is available through demonstration software, OEM custom software, or using standard TWAIN
applications. Features include:
● Fast upload through USB, or upload through RS232.
● Colour display of image thumbnails for picture selection.
● Download of full image once selected by user software.
● Automatic detection and correction of sensor defects
● Colour processing of full image, using the ST colour process
The above features also apply to “AVI Creator” or any OEM custom software for AVI video creation
from pictures taken while un-tethered, since this is essentially a “stills” function.
5.1.2 Streaming video (only while tethered to USB)
This is available through demonstration software, or using standard VfW applications. Features
include:
● Streaming video through standard VfW driver
● Automatic detection and correction of sensor defects
● Colour processing of full image, using the ST colour process
5.2
Software installation
The following software support is only available to OEMs. Access to the latest installation files is
possible through a password-protected web page, contact ST for details. The install file gives the
option to install:
● Drivers (always check web site for latest driver version).
● EVK software, i.e. LCDCdemo.exe and AVIcreator.exe, G2Video.exe, and CTItest2.exe
● SDK installation: source code for sample applications, and documentation

Note: The following is also supplied with evaluation kits/demonstration units, but all the following software
is only for demonstration purposes and should NOT be supplied as an end-user product. However,
application-level source code (i.e. not driver/colour processing source) for LCDCdemo.exe, AVI
creator, and CTItest.exe is available as part of the SDK, which allows similar applications to be built
by the software developer:
1

3
Simple demonstration software LCDCdemo.exe for uploading thumbnails and images.
AVIcreator.exe software for uploading continuous images for creating ‘movie’ clips.
G2Video.exe is a VfW application which shows streaming video while tethered to USB and
allows creation of.AVI video clips.
4
CTItest.exe is only for debugging purposes, for software developers using the SDK
5.2.3 Software Development Kit (SDK) and source code
A software development kit allows the OEM to develop a custom application which calls the same
range of drivers as listed in Section 5.2.1, hence allowing the OEM application to perform picture
download, thumbnail display, and colour processing using the ST colour process. Inclusion of
source code for the applications listed in Section 5.2.2 allows the software developer to use these
as the basis for their own application.
TM
The SDK is supplied by ST as a 32-bit DLL format, running on Windows 98/Win2K , and accessed
through a documented software interface. Development requires Microsoft Visual Studio Ver. 6 or
later. This provides the basis for developing a custom software application for stills.
Note: Source code for PC Drivers, Defect Correction, and Colour Processing algorithms are not available.

placed in Sensor Suspend mode by means of (a) a Serial interface message and (b) the SUSPEND
pin being asserted.
2 Where the external hardware does not permit the sensor SUSPEND pin to be asserted (during
Standby Mode/PC Suspend Mode, the sensor is placed in Sensor Suspend mode by means of a

STV0680 Camera System Defect Specification
Note: The information in this chapter is subject to change without notice. Contact ST for precise details
and information on correct driver versions.
7.1
General
ST CMOS Sensors can contain defects as part of their standard sales specification. The sensor
defect specification, if required, can be found in the appropriate sensor datasheet, however this
specification is not the same as the camera system defect specification.
When an ST CMOS Sensor is used in a STV0680B camera system, a defect correction algorithm in
the camera system will correct the sensor defects so that in the vast majority of cases the user
should not see defects in the final colour image generated by the PC/Mac driver. This chapter
clarifies the defect specification for the overall camera system.
7.2
Defect specification
When using the specified Camera System, under the specified Test Conditions:
1
2
3
No Major Visible defects are allowed in the Final Colour Image from a CIF camera (VV6410/
6411/6444) or VGA Camera (using VV6500 shipped by ST until end of Q1 2001), except under
certain limitations given in Section 7.2.1 and Section 7.3.7.
No Major Visible defects are allowed in the "Inner area" (within the central 242 x 322 pixels) of
the Final Colour Image from a VGA camera (VV6500 shipped by ST after start of Q2 2001),
except under certain limitations given in Section 7.2.1 and Section 7.3.7.
Some Minor Visible defects are allowed in the "Outer area" (outside the central 242 x 322
pixels) of the Final Colour Image from a VGA camera (VV6500 shipped by ST after start of Q2
2001), but no Major Visible Defects are allowed in the "Outer area", except under certain
limitations given in Section 7.2.1 and Section 7.3.7.
7.2.1 Appearance of defects under other conditions
During normal camera use (e.g. lensed camera used in a “real situation”), it is possible that defects
may be visible under certain conditions:
● At the sharp edge of certain light/dark transitions
7.3
Definition of the "Camera System"
All of the following conditions must be met for the defect specification to be applicable to the
"Camera System".
Note that the EVK units STV-DCA/CIF-E01 or -E04 and STV-VGA/VGA-E01 or -E04 both conform
to these conditions, hence have the same defect specification as detailed in Section 7.2.
7.3.1 CMOS Imaging Sensor
The defect specification applies to the Camera System if any of the following sensors are used.
● VV6444-C001
● VV6410-C036
● VV6411-C036

7.3.2 Companion ASIC
The defect specification applies to the Camera System, if any of the following companion ASICs are
used, subject to the firmware notes shown in Section 7.3.3:
● STV0680
● STV0680A
● STV0680B
7.3.3 Companion ASIC Firmware:
Only standard firmware sold by ST is covered by this defect specification. Any OEM modification of
companion ASIC firmware through the STV0680 FDK means that this defect spec does not apply.
Devices containing standard firmware are sold under the following order codes:
● STV0680-001
● STV0680A-002
● STV0680B-001
● STV0680B-003
7.3.4 Camera Hardware
Camera built according to the ST Imaging Division Reference Design, including any of the options
shown.
7.3.5 Host Interface
USB or RS232 interfaces can be used.
7.3.6 Host Operating System
● PC running Windows 98, Windows 2k, Windows ME, or Mac running Mac OS 8.6 or above.
● PC Drivers with VV6444/6410 and VV6500 until end Q1 2001: Version 1.00 or above.
● PC Drivers with all sensors, including VV6500 shipped after start of Q2 2001: Version 1.14 or
above.
7.3.7 PC Software:
● Standard TWAIN Interface (PC) or Photoshop compatible plug-in (Mac)
● LCDCdemo.exe (see note 1), AVICreator.exe, or other OEM application generated through
SDK (see note 1).
● Any VfW Application (see note 2) on PC or Quicktime application on Mac.
Notes on non-default software settings:
Note: 1 With the "Greyscale" checkbox enabled in LCDCdemo.exe, uploading a full resolution image by
double clicking on the image thumbnail will produce a raw “Bayer” image which can include defects.
The "Greyscale" facility is intended for OEM debug purposes only, and cannot be regarded as a
“final colour image”.
2 When running any VfW application, the Source->Advanced->Anti-Speckle function can be used to
enable/disable defect correction and select the correct method of defect correction in the final
colour image. Hence it is possible to see defects when the "Anti Speckle" checkbox is cleared, or
when the anti-speckle filter does not match the sensor type.

● Sensors VV6500 shipped after start Q2 2001 require Anti-speckle 2
7.4
Definition of the "Test Conditions"
7.4.1 Optics
● No Lens or IR filter
● No dirt on sensor glass
7.4.2 Illumination and uniformity of scene
No lens should be used. The intensity of required illumination and the uniformity of the scene can be
defined thus. A defect-free image should give a luminosity histogramme (8 bits resolution) with the
following statistics:
1
Mean: (45% of full scale) < Mean < (65% of full scale). Ideal luminosity (mid grey) = 50-60% of
full scale.
2
Standard Deviation: Standard Deviation < 10.
7.5
Definition of a "Major Visible Defect"
Anything which is visible with the naked eye under the conditions described, is worthy of further
investigation. For example:

Note: Not all compatible memory chips exhibit a low enough self-refresh current to meet the target
current for USB suspend mode (see Table 17). Two memory types have been suggested in Table
18, based on limited evaluation by ST, however this does not constitute a full characterisation, and
no guarantees can be made that the self-refresh current consumption will match the target for USB
suspend mode in all cases. Please consult the memory manufacturer

Evaluation Kit and Reference design manual
12 Evaluation Kit and Reference design manual
STMicroelectronics recommends using the Evaluation Kit for initial evaluation and design-in.
Both evaluation kits (STV-DCA/CIF-E04 and STV-DCA/VGA-E04) now include audio record and
playback circuitry as well as flashgun interface circuitry and a flashgun hotshoe connector (to allow
the OEM to use a standard camera flashgun), allowing the new features as well as the existing fea-
tures to be demonstrated.
Also included are a STV0680B + CMOS sensor chipset, memory, lens, connectors, LCD, battery
holder, push buttons/switches, and other components as detailed. Optional PCB links enable alter-
nate functionality, and demonstration software is included, allowing for tethered video, upload to the
PC of pictures, sounds, and AVI movie clips, and download to the camera of custom sounds.
A reference design manual is available, giving the camera designer everything required to design a
complete camera with standard features. It includes schematics, explanatory notes, parts list and
layout advice. Audio and flashgun hardware are the subject of separate applications notes, contact
ST for details.
