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.
