1 Introduction
The FT4232H Mini Module is a USB-serial/FIFO development module in the FTDI product range which
utilizes the FT4232H USB Hi-Speed four-port bridge chip which handles all the USB signalling and
protocols. It is ideal for development purposes to quickly prove functionality of adding USB to a target
design. The FT4232H datasheet, DS_FT4232H, is available at http://www.ftdichip.com,
Figure 1.1 - FT4232H Mini Module
The FT4232H on the Mini Module is FTDI’s 5th generation of USB devices. The FT4232H is a USB 2.0 High
Speed (480Mb/s) to UART/MPSSE IC. The device features four interfaces that can be configured for
asynchronous or synchronous serial or parallel FIFO interfaces. Two of these have an option to
independently configure an MPSSE engine. This allows the FT4232H to operate as two UART/Bit-Bang
ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial
modes. All components used, including the FT4232H are Pb-free (RoHS compliant).
The FT4232H Mini Module connects the signals of the FT4232H IC to two 26-pin dual-row headers which
allow easy connection PCB header sockets and ribbon cables.
The FT4232H Mini Module requires USB device drivers, available free from http://www.ftdichip.com,
which are used to make the FT4232H on the Mini Module appear as a four virtual COM ports (VCP). This
then allows the user to communicate with the USB interface via a standard PC serial emulation port
(TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly
access the FT4232H on the Mini Module though a DLL. This is illustrated in the Figure 1.2

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:
1) Connect VBUS to VCC (CN3, pin 1 to CN3, pin 3). This connection takes the power from the
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.
2) Connect V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 & 21 and CN3, pins 12 & 22).
This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT4232H chip.
USB Self-Powered:
1) Leave VBUS (CN3, pin 1) unconnected.
2) Connect an external 5.0VDC power supply to VCC (5.0VDC to CN3, pin 3). This
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.
3) Connect V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 & 21 and CN3, pins 12 & 22).
This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT4232H chip.
4) Use MPROG to change the USB power descriptor to “Self-Powered”. This setting indicates
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. MPROG is available
through the Utilities section of the FTDI web site.
