SE401

The SE401 USB Video Imager Controller is designed to form the core of a low-cost USB video camera. It is a single chip solution to control the image sensor and move the image data to the Universal Serial Bus. The only additional major components required are the CMOS image sensor and external DRAM to provide working storage for the compression engine. With the addition of an audio codec, the SE401 can also support sound,enabling a variety of audio and video applications.

The SE401 consists of a central 16-bit processor,an EndPoints-proprietary compression engine,masked ROM, a RAM buffer, a clock generator, and a flexible, extensible series of interfaces. The block diagram shows one example of the SE401 and its interfaces. Other variations can be implemented using external expansion ROM and the SE401's General Purpose Input/Output (GPIO) facilities.
