PAC7332 VGA PC Camera Single-Chip with Audio
General Description
The PAC7332 is a single chip with an embedded VGA CMOS image sensor and USB 1.1 interface. It has JPEG
image compression and image processing. The generic application is a PC camera. And the optical size is 1/6”
which can easily be embedded in LCD monitors, notebooks or PDA. It also provides high quality audio sampling
function for sound recording. It is fully compliant with USB Video Class 1.0 and USB Audio Class 1.0 standard.
PAC7332 supports the interface to a serial-EEPROM. When the EEPROM function is enabled, the internal
