2 / 60 page 2001 May 04 2 Philips Semiconductors Product specification Digital PC-camera signal processor including microcontroller and USB interface SAA8116 FEATURES • Embedded microcontroller (80C51 core based) for control loops Auto Optical Black (AOB), Auto White Balance (AWB), Auto Exposure (AE) and USB interface control • Compliant for VGA CCD and VGA CMOS sensors (RGB Bayer) • USB 1.1 compliant bus-powered USB device with integrated power management and POR circuit • RGB processing • Optical black processing • Defect pixel concealment • Programmable colour matrix • RGB to YUV transform • Programmable gamma correction (including knee) • Programmable edge enhancement • Video formatter with SIF/QSIF downscaler • Compression engine • Flexible Measurement Engine (ME) with up to eight measurements per frame • Internal Pulse Pattern Generator (PPG) for wide range of VGA CCDs (Sony, Sharp and Panasonic) and frame rate selection • Programmable H and V timing for the support of CMOS sensors • Programmable output pulse for switched mode power supply of the sensor • 3-wire interface to control an external pre-processor IC, such as the TDA8787A: Correlated Double Sampling (CDS), Automatic Gain Control (AGC) and 10-bit ADC • Analog microphone/audio input to USB: Low DropOut (LDO) supply filter, microphone supply, low noise amplifier, programmable amplifier, PLL and ADC • Integrated analog USB driver (ATX) • Integrated main oscillator, including a clock PLL, which derives 48 MHz main system clock from a 12 or 48 MHz fundamental crystal. APPLICATION • USB PC-camera (video and audio). GENERAL DESCRIPTION The SAA8116 is a highly integrated third generation USB PC-camera ICs. It is the successor to 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, I2C-bus, 512 bytes of RAM and 32 kbytes of program memory is embedded in the SAA8116. 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.
