Sensor Interface
• Support CCIR-656 8-bit YUV interface
• Supports fast serial interface to program image sensor.
Host Interface
• 8/16 bits parallel Bus (Indirect access)
• Easy for base band chip( Host ) to develop Camera function through Command set protocol.
LCD Display Interface
• Support up to dual LCD Panels interface
• Supports MCU type interface LCD module
• Supports 8/16/18-bit display data output to LCD Penal
• Support 4 kinds of display data format out to LCD Penal

− 64k colors (RGB-565)
− 256k colors (RGB-666)
• Support LCD interface bypass mode
• Support TFT-LCD, CSTN-LCD, STN-LCD Panel Types
• If camera function is active, the host CPU can use W99685BS as the bridge (display controller) to LCM. And it can provide multiple display buffers.
• If camera function is disabled, the host CPU can use bypass mode to control the LCM directly for maximum power saving.
JPEG CODEC for Image Compression and Decompression
• Fully compliant with ISO/IEC 10918-1 international JPEG standard
• JPEG compression and decompression for still images
• Real-time motion JPEG (M-JPEG) compression with advanced bit rate control for live video
• JPEG baseline sequential mode in interleaved scan YcbCr(4:2:2) or YcbCr(4:2:0) format
• Support adjustable quantization table for different compression ratio
• Support smooth digital zoom
• Support JPEG re-sizing and re-encoding

W99685BS is a high performance and highly-integrated system camera device that it can preview, capture, compress, store, and display the digital still images or playback a short period of live video. This chip provide 8 or 16 Bits Host interface and easy for base band platform( Host ) to develop Camera function through Winbond CF Command set protocol that allow the development of products without knowing any W99685BS chip programming.W99685BS Built-in 8-bit 8032 compatible uC with internal 16KB program RAM and 4K data RAM.

Program W99685BS can be down load from memory bus interface. This chip also Built-in 2M byte frame buffer for real-time video clip (MJPG) and burst snapshot. Support CCIR-656 8-bit YUV CMOS or CCD capture sensor interface.

W99685BS Support up to dual LCD Panels interface with MCU type interface. Support TFT-LCD, CSTN-LCD, STN-LCD Panel Types , If camera function is active, the host CPU can use W99685BS as the bridge (display controller) to LCM. And it can provide multiple display buffers. If camera function is disabled, the host CPU can use bypass mode to control the LCM directly for maximum power saving.

W99685BS Support dual video pipes and double buffering for real-time motion JPEG, Support smooth scaling-down of video pipes, different kinds of raw data formats for display, some popular image color effects ( Black & White,Sepia,Negative,Solarize or Oil Painting ), video rotation/mirror/flip for capture and playback,sticker maker, Comic Photo maker and smart frame rate control.
