W99688CBM3 is system camera device which built-in 1Mx16bit SDRAM and 128Kbyte Flash ROM. The W99688CBM3 also 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.

In addition to transfer image data, the W99688CBM3 allows to download the programs of micro controller through the USB to update the external flash program ROM, which allows for end users with firmware upgrades through the Internet. W99688CBM3 supports CMOS image sensors with high performance DSP functions including missing color interpolation, AE(Auto Exposure), AWB (Auto White Balance), Gamma Correction, edge enhancement, contrast stretching, hue and saturation adjusting etc.

W99688CBM3 has built-in the baseline JPEG codec for image compression and decompression, which corresponds to the ISO/IEC international standard 10918-1, with YCbCr4:2:2 or YCbCr4:2:0 components in interleaved scan. W99688 also supports the Exchangeable Image File format (EXIF) to ensure data compatibility and exchangeability.

W99688CBM3 includes an 8032 compatible CPU core, a 6K-byte SRAM and two 16-bit programmable timers. W99688CBM3 also provides the In-System-Programming (ISP) function to let users to update the firmware for external flash ROM.

W99688CBM3 also supports a digital display output to directly interface with TFT-LCD, CSTN-LCD or other display device.
