APPLICATIONS
GENERAL DESCRIPTION
The SAA8116HL is a highly integrated third generation of
USB PC-camera ICs. It is the successor of the
SAA8112HL and SAA8115HL. It processes the digitized
sensor data and converts it to a high quality, compressed
YUV signal. Together with the audio signal, this video
signal is then properly formatted in USB packets.
In addition, an 80C51 microcontroller derivative with five
I/O ports, I
program memory is embedded in the SAA8116HL. The
microcontroller is used in combination with the
programmable statistical measurement capabilities to
provide advanced AE, AWB and AOB. The microcontroller
is also used to control the USB interface.
USB PC-camera (video and audio).
