UM232H Single Channel USB Hi-Speed FT232H Development Module Error!
Unknown document property name.
Datasheet Version 1.3
Clearance No.: FTDI# 198
Self-Powered Configuration with 3V3 I/O and running on +3.3V external supply:
Figure 7.5 : Self-Powered Configuration – 3V3 External Supply
Figure 7.4 illustrates the UM232H in a typical USB Self-Powered configuration similar to Figure 7.3. The
difference here is that the UM232H module is powered from an external 3.3V supply which is connected to
the 5V0 (+3V3 power supply input can also be supplied to 5V0 pin), VIO and 3V3 pins of the modules.
Please note that when the UM232H running from +3V3, the 3V3 pin becomes an input. The VIO and 3V3
pins connection provides 3V3 to the VCCIOs, VPLL and VPHY on the FT232H chip.
Simularly to the USB-Powered configuation an alternative configuration which utilised PWRSAV# can be
implemented. Figure 7.6 illustrated this configuration.
