1. GENERAL DESCRIPTION

W99685FS 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 chip( Host ) to develop Camera

function through Command set protocol that allow the development of products without knowing any

W99685FS chip programming.

W99685FS Built-in 8-bit 8032 compatible uC with internal 16KB program RAM and 4K data RAM.

Program can be down load from Host 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.

W99685FS 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 W99685FS

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.

W99685FS Support dual video pipes and double buffering for real-time motion JPEG, Support smooth

digital zoom 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.
