| OV3640 3.1 Megapixel product brief available in a lead-free package 1/4-inch, high-performance 3 Megapixel CameraChipTM sensor with image stabilization and MIPI The OV3640 is a feature-rich, high-performance 3.1 Megapixel CMOS CameraChipTM sensor in a 1/4 inch optical format. It is based on OmniVision's new 1.75m OmniPixel3TM architecture with ultra low stack height (ULSH) for excellent low light sensitivity (500mV/lux-sec) and significantly improved noise and dynamic range (65dB). The highly integrated OV3640 incorporates an extremely advanced Image Signal Processor (ISP) with new features such as an advanced image stabilization/anti-shake (AS) engine that requires no external components. An embedded microcontroller supports the internal auto focus (AF) engine and the programmable general purpose I/O modules enable external auto focus control. The OV3640's image array operates at up to 15 frames per second (fps) in full 3-megapixel resolution (QXGA) transferred over a two lane MIPI interface or a traditional digital video port (DVP). The sensor also contains an integrated compression engine (JPEG), simplifying bandwidth limited interfaces. The fully integrated and feature-rich OV3640 is small enough to fit standard 8 x 8 mm fixed focus sockets as well as 8.5 x 8.5mm AF sockets, making it ideal for drop-in upgrades of existing camera modules used in existing lower mega-pixel camera phone designs. The OV3640's ISP can also be used by an external secondary camera via its DVP while providing continued output through the MIPI interface for the primary camera. For identification purposes, the OV3640 also includes a one time programmable (OTP) memory. All required image processing functions are programmable through the SCCB interface or the integrated micro-controller. applications cellular phones toys PC multimedia digital still cameras OV3640 ordering information OV03640-VL9A (color, lead-free, 56-pin CSP2) (color, no chip probing, no backgrinding) OV03640-G00A product features ultra low power and low cost automatic image control functions: - - - - - automatic exposure control (AEC) automatic white balance (AWB) automatic band filter (ABF) automatic 50/60 Hz luminance detection, and automatic black level calibration (ABLC) product specifications support for: - video or snapshot operations - auto focus control (AFC) - horizontal/vertical sub-sampling, data compression output, auto focus control (AFC) and anti-shake - internal and external frame synchronization - LED and flash strobe mode - support for second camera chipsharing MIPI interface array size: 2048 x 1536 power supply: core: 1.5VDC + 5% analog: 2.5 ~ 3.0V digital: 1.7V ~ 3.0V input clock frequency: 6 ~ 54 MHz maximum image transfer rate: QXGA (2048 x 1536): 15fps for QXGA and any size scaling down from QXGA XGA (1024 x 768): 30fps for XGA and any size scaling down from XGA support for output formats: RAW RGB, RGB565/555/444, YUV422/ 420, YCbCr422 and compression programmable controls for frame rate, AEC/AGC 16-zone size/ position/weight control, mirror and flip, scaling, cropping, windowing, and panning image quality controls: color saturation, hue, gamma, sharpness (edge enhancement), lens correction, defective pixel canceling, and noise canceling standard serial SCCB interface digital video port (DVP) parallel output interface MIPI serial output interface embedded microcontroller embedded one-time programmable (OTP) memory integrated anti-shake output format (8-bit): YUV(422/420) / YCbCr422, RGB565/555/444, 8-bit compression data, 8-/10-bit raw RGB data lens size: 1/4" image area: 3626 m x 2709 m chief ray angle: 25 non-linear pixel size: 1.75 m x 1.75 m temperature range: operating: -20 C to 70 C stable image: 0 C to 50 C functional block diagram OV3640 image sensor core column sample/hold compression engine image sensor processor image output interface digital gain black level calibration row select image array AMP 10-bit A/D formatter 10-bit RAW DSP DVP FIFO DATA[9:0] MIPI 50/60Hz auto detection gain control control register bank SCCB slave interface MIPI control interface PLL timing generator and system control logic micro controller GPIO[3:0] XVCLK RESET_B HREF FREX external sensor input SCL PWDN STROBE VSYNC PCLK SDA 3640_PB_001 1341 Orleans Drive Sunnyvale, CA 94089 tel: +1 408 542 3000 fax: +1 408 542 3001 www.ovt.com OmniVision reserves the right to make changes to their products or to discontinue any product or service without further notice.
