1 Product Overview STK2139 is a highly integrated, USB 2.0 compliant single chip NB camera / PC camera controller. Utilizing a high-speed, high-bandwidth isochronous pipe, it is able to transfer image data at the rate up to 24MB/s. An interrupt pipe is available to carry status to USB host. STK2139 is optimized to support image sensors with YUV data output. The processed resolutions can be up to 2MP image sensor. The image data can be further processed by adjusting brightness, contrast, hue, and saturation. STK2139 supports serial flash or EEPROM to store data and program code for internal 8051. This adds system flexibility to support variant image sensors. - 4 -
