I would like to add a 3rd USB device controller port to my MCU. I looked for parts and ended up with two solutions:


a) use FT120 which interfaces to MCU via parallel bus (


b)Use MAX4320E. This is SPI to USB  (


is option(a) doable ? This means configuring the EMC to interface with FT120. I am worried about not getting EMC configured right. Option (b) looks simpler but I am worried about achieving lower USB bandwidth than If I was going with option (a)
