GENERAL DESCRIPTION
The Colour Processor Interface ASIC (CPiA) is a digital video processor requiring only a single 4Mbit DRAM and minimum of passive support components to provide a complete PC peripheral video capture system.
CPiA accepts raw digital video data from Vision’s CIF format CMOS sensors and is capable of transferring the resulting YUV video data to a host PC over either USB or Parallel Port interfaces at rates up to 30 frames per second.

FEATURES
• Interfaces to Vision’s VV6404 colour CMOS image sensor
• Directly interfaces to a host PC using USB or Parallel port interfaces
• 100% compliant with USB specification v1.0
• 100% compliant with IEEE1284 parallel port specifications
• Support for Windows 95/98 Plug and Play
• Image capture at CIF (352x288) and QCIF(176x144) resolutions
• Image compression providing up to 30fps CIF
• Automatic exposure control and colour balance
• Camera flicker control for 50 Hz and 60 Hz mains driven lighting
• Supports selective transfer of requested regions of interest to the host system
• Power management including watchdog reset
• Absolute minimum of support components
• Device pinout designed to facilitate layout and area of support PCB
