BU6566GVW-E2

Video Processing Overview

The BU6566GVW-E2 is a camera image processor compatible with standard JPEG, designed for home electronics and security devices. It supports VGA size (640x480) input at up to 15 fps. The device features a built-in camera module interface accepting YUV=4:2:2 and RGB=4:4:4 formats, along with filter processing capabilities including grayscale, sepia, emboss, edge enhancement, and negative effects. It includes an 80KB frame memory usable as JPEG code memory or ring buffer. The processor integrates a JPEG codec conforming to ISO/IEC10918 baseline method, supporting compression for YUV=4:2:2 and decompression for various subsampling formats. A built-in LCD controller interface allows connection to displays supporting up to 262,144 colors.

Video Processing Feature Summary

• Built-in camera module interface supporting VGA resolution input with multi-step size reduction and arbitrary cutting functions.
• Integrated JPEG codec for compression and decompression of image data stored in internal frame memory.
• Built-in LCD controller interface enabling direct connection to display modules with overlay support for icons and fonts.
• Comprehensive image processing filters including brightness adjustment, D-range enlargement, and multiple visual effects.

Video Processing Applications

• Security cameras
• Intercom systems with camera functionality
• Drive recorders
• Web cameras

Video Processing Procurement Notes

Verify the specific suffix E-2 against the manufacturer's official documentation to confirm exact ordering specifications and compliance status. Ensure that the power supply sequencing adheres strictly to the recommended order of VDD, followed by VDDIO1, and then VDDIO2 to prevent operational faults. Confirm compatibility with the target host CPU interface requirements before integration into the final design.

Video Processing Selection Notes

Select this component for applications requiring integrated image capture, processing, and display control within a compact form factor. The BU6566GVW-E2 is suitable for systems needing JPEG compression without external memory controllers due to its built-in frame memory. Consider the pin-to-pin compatibility with the BU6568GV if future high-resolution upgrades are anticipated, although this specific model is optimized for VGA inputs.

Video Processing Part Context

This part belongs to ROHM's Camera Image Processor Series, specifically designed for home electronics and security applications. It offers a solution for handling image data from camera modules directly to LCD displays or storage via JPEG encoding. The series emphasizes low power consumption and reduced system complexity by integrating multiple functional blocks into a single chip.

Video Processing Replacement Considerations

The BU6568GV is documented as pin-to-pin compatible with the BU6566GVW series, offering support for higher resolution SXGA inputs while maintaining the same package and interface structure.

Video Processing FAQ

What image processing filters are available on the BU6566GVW?

The device supports filter processing for input images, including 2 gradations, gray scale, sepia, emboss, edge enhancement, and negative effects.

Can the internal frame memory be used for purposes other than storing camera images?

Yes, the 80KB frame memory can be used as JPEG code memory to store compressed images or as a ring buffer for JPEG codes exceeding 80KB.

Does the BU6566GVW support direct access to LCD modules?

Yes, it features a built-in LCD controller interface that allows direct access to LCD modules, supporting parallel and serial transmission modes.
