FT2232C Dual USB UART / FIFO I.C.
A USB self powered design uses its own power supplies, and does not draw any of its power from the USB bus. In
such cases, no special care need be taken to meet the USB suspend current (0.5 mA) as the device does not get its
power from the USB port.
As with bus powered 3.3V interface designs, in some cases, where only a small amount of current is required (<5mA),
it may be possible to use the in-built regulator of the FT2232C to supply the 3.3V without any other components being
required. In this case, connect VCCIOA or VCCIOB to the 3V3OUT pin of the FT2232C.
Note that if the SI/WU pins are not being used they should be pulled up to the same supply as their respective VCCIO
pin.
