I'm planing on connecting an AVR to usb using PL2303.
Since the datasheet is seriously lacking in information I tried searching for application note but couldn't find anything.
The only thing I managed to find was this schematic.
-Some of the pins in this schematic don't match the pins in the datasheet though.
For example, the PLL supply voltage is not connected in the schematic.
-Also I'm trying to figure out why R1 pulls up the D+ line to 3v and not 5v.
It also seems that pin (number 17) is a 3v3 power pin, do I need to supply it 3v3 too ?
I'm so confused.
-How do I set the speed and data format ? I don't see any option for that in the config eeprom.
Is there any decent source of information about this chip ? Any app notes or anything ?
I have searched this forum, but couldn't find anything more than the schematic above.
