Table 3.2 FT4232H Mini Module Connection – CN3
In most cases, the FT4232H pin is connected directly to the associated pin on CN2 or CN3.
The FT4232H Mini Module allows configuration with both USB Bus-powered designs and USB Self-
powered designs:
USB Bus-powered:
USB Self-Powered:
1) Connect VBUS to VCC (CN3, pin 1 to CN3, pin 3). This connection takes the power from the
2) Connect V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 & 21 and CN3, pins 12 & 22).
1) Leave VBUS (CN3, pin 1) unconnected.
2) Connect an external 5.0VDC power supply to VCC (5.0VDC to CN3, pin 3). This
3) Connect V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 & 21 and CN3, pins 12 & 22).
4) Use MPROG to change the USB power descriptor to “Self-Powered”. This setting indicates

USB bus (VBUS) and connects it to the voltage regulator input on the FT4232H Mini Module. The
voltage regulator, in turn, provides V3V3, VPLL and VUSB power inputs to the FT4232H chip.
This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT4232H chip.
connection takes provides power from an external power supply and connects it to the voltage
regulator input on the FT4232H Mini Module. See the FT4232H data sheet for allowable VCC
input voltage ranges.
This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT4232H chip.
to the host system that the USB Host port does not need to supply power to the device. MPROG
is a utility provided by FTDI to program various features of the FT-series USB client ICs. In order
to access settings for the FT4232H, MPROG, version 3.5 or later is required.
