Figure 6.3 Self Powered Configuration Example 1
Figure 6.3 illustrates the FT2232H in a typical USB self powered configuration. A USB self powered device
gets its power from its own power supply and does not draw current from the USB bus. In this example
an external power supply is used. This external supply is regulated to +3.3V.
Note that in this set-up, the EEPROM should be configured for self-powered operation and the option
“suspend on DBUS7 low” selected in MPROG. Also this configuration uses the pin BCBUS7, so this
assumes that MPSSE mode is not selected.
