PAC7302 VGA Output PC Camera SOC with Audio

PAC7301 VGA Output PC Camera SOC without Audio

General Description

The PAC7301/PAC7302 is a VGA output PC Camera SOC with embedded CMOS image sensor and

USB 1.1 interface. It embedded a JPEG image compression engine and an image signal processor

(ISP). The JPEG decoder and auto exposure control are performed by software in PC side. The

PAC7301/PAC7302 can achieve a compact module size by using it’s 1/6” optical size which can easily

be embedded in LCD monitors and notebooks. The chip provides IO-trapping pins with internal pull-up

resistors. Hence it is flexible 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 the external EEPROM. This allows customization of VID, PID, product string…etc.

PAC7301/PAC7302 also provide a high quality audio ADC function for sound recording. The audio-in

function complies with USB audio device class 1.0. The PAC7301/PAC7302 is powered by 5V and in

PLCC/CSP/LGA package
