General DescriptionThe PAC7302 is a VGA output PC Camera SOC with embedded CMOS image sensor and USB
1.1interface. It embedded a JPEG image compression engine and an image signal processor (ISP). TheJPEG decoder and auto exposure control are performed by software in PC side. The PAC7302 canachieve a compact module size by using it’s 1/6” optical size which can easily be embedded in LCDmonitors and notebooks. The chip provides IO-trapping pins with internal pull-up resistors. Hence it isflexible for customers to set PID on module PCB. It supports an interface connect to a serial-EEPROM.When the EEPROM function is enabled, the internal control register setting will be auto loaded to theexternal EEPROM. This allows customization of VID, PID, product string…etc. PAC7302 also provide ahigh quality audio ADC function for sound recording. The audio-in function complies with USB audiodevice class
1.0. The PAC7302 is powered by 5V and in PLCC/CSP/LGA package1.
