PAC7332 is a USB PC Camera SOC with enhanced image quality and sensitivity, internal regulators, JPEG

image compression, image processing schemed, control registers, on-chip SRAM for image data buffer and USB

controller. And the JPEG compressed image data is transmitted by USB 1.1 isochronous pipe. PAC7332 supports

the interface to a serial-EEPROM. When the EEPROM function is enabled, the internal control registers can be

power-up loaded from external EEPROM. This allows customization of VID, PID, product string…etc.
