SE401
USB Video Image Controller
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鈥?/div>
