Hi, I'm using a FT245R in my design and I'm seeing fairly low transfer rates; What I'm seeing on the FT245 side, is that RXF# is high most of the time, so it looks like the host is not sending enough data / not fast enough or in too many short packets.
What I was wondering: the FT245R datasheet claims (quote:) "Data transfer rates up to 1Mbyte / second." But, since it is a fullspeed device (1ms frames) and it has 128 byte receive buffer, I figure the maximum tranfer rate is limited to 1000x 128 bytes per second? (equal 125Kb/s) In other words: the receive buffer can be filled with at most 128 bytes every 1ms... How is the 1 MB/s even theoretically possible with a 128 byte receive buffer?
