I get this table for possible USB Bridge candidates :ĮFM8UB1(MCU) CP2102N CP2130 XR21B1420 FT245R FT240X FT232H FT2232H FT4222-C NUC505DLA(MCU) FT600 FT93xĭata Rates 3-4MBd 3-4MBd 3~6MHz SPI ~9MBd 1 MB/s FIFO 1MB/s FIFO 8 MB/s*FIFO 8 MB/s*FIFO 6.725 MB/s HS-USB,QSPI SS,HS USB FIFO HS USB There are many connection choices, and parallel FIFO is the fastest, but has a somewhat high pin-cost. Mostly I am talking about a PC here, but maybe there are a lot of people right now that would be thinking also in a Rasberry PI, Udoo x86, Odroid, LattePanda, x86duino, Up Board, Olinuxino. The second part or the problem is how to do high speed transfer from P2 into a computer.
