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