AV328C,AV301W-XG7,AV306i-XG7,AV306E-XG7
General description
AV328C is USB2.0 camera controller mainly for external PC camera market,
which is designed on the basis of AV318 series. It can use XP/Vista/Win7
built-in USB video class. And It has 8K OTP (one-time programmable) memory, no
need add external EEPROM. It also supports SPI interface and DMA. The USB
endpoints are 1 Control, 1 INT and 1 ISO IN.
AV301W-XG7 is USB2.0 camera controller. Its small size can be
used for compact camera module dimension and mainly for notebook
built-in. It has the same function as AV328C except 2 less pin
count. The USB endpoints are 1 Control, 1 INT and 1 ISO IN.
AV306i-XG7 is USB2.0 camera controller. It has the AV328C
function plus the USB audio class support. Audio supports up to
Vista’s dual Microphone array feature through an external I2S codec.
This ASIC can be used as PC camera with audio function or USB audio
device.
The USB endpoints are 1 Control, 1 INT and 2 ISO IN.
AV306E-XG7
is USB2.0 camera controller which has more enhanced functions than
AV306i-XG7. This video processor provides more solutions for video
and image application, such as T-flash card reader, SPI flash
interface, wireless USB dongle, RS232 interface etc. The USB
endpoints are 1 Control, 1 INT, 1 Bulk IN, 1 Bulk Out and 2 ISO IN.
