looking for usb module to program some chips

hi i'm looking for a module that has a micro usb and send the incoming data via com port communications to some pins either via parallel outputs (i need it to drive like 24 bits) or serial output (clock and serial data). it need it to have a signed driver of course and works for all windows versions, And i don't want to use arduino. i searched i i found CP2102 is probably what i'm looking for. but i didn't find tutorials about it and didn't well understand the datasheet

thank you.

I did a search for 32 io usb expander

Might have something of interest.

Not sure if it will work with e.g Windows 3.1 8)

Out of curiosity, why no Arduino?

it's not quite what i need. i need to pass some serial data to fpga via some of its pins, the arduino has 16MHz clock which is quite slow.

Maybe you must elaborate a bit. You have a pc with data that needs to be transferred to an fpga using synchronous serial comms or parallel comms?

Compared to serial data, an Arduino is not slow ;) You are aware that the uart 'module' on an AVR can be used for synchronous serial communications? Use e.g. a Mega or Leonardo so you don't sacrifice the USB communications.

Just out of curiosity, what's wrong with the portexpander?
