OMNIVISION OV03640-G00A

OV3640 3.1 Megapixel product brief
available in
a lead-free
package
1/4-inch, high-performance 3 Megapixel CameraChip™
sensor with image stabilization and MIPI
The OV3640 is a feature-rich, high-performance
3.1 Megapixel CMOS CameraChip™ sensor in a
1/4 inch optical format. It is based on OmniVision's
new 1.75μm OmniPixel3™ 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.
