<strong>PAP7501V</strong> <strong>USB2.0</strong> <strong>PC</strong> <strong>Camera</strong> <strong>Controller</strong><br />
<strong>PAP7501V</strong><br />
General Description<br />
The <strong>PAP7501V</strong> High-Speed <strong>USB2.0</strong> <strong>Camera</strong> <strong>Controller</strong> is a highly integrated and cost-effective solution for<br />
<strong>USB2.0</strong> <strong>PC</strong>-<strong>Camera</strong> based applications. It is fully compliant with USB Video Class 1.1 and USB audio class 1.0<br />
standard.Internal controller can be power-up loaded from external EEPROM. This allows customization of VID,<br />
PID, product string, sensor parameters…etc.<br />
