1 Introduction
The FT2232H-56Q Mini Module is a USB-serial/FIFO development module in the FTDI product range which
utilizes the FT2232H-56Q USB Hi-Speed dual-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 FT2232H datasheet, is available at http://www.ftdichip.com/Products/ICs/FT2232H.html.
Figure 1.1 FT2232H-56Q Mini Module
The FT2232H-56Q Mini Module is a USB 2.0 High Speed (480Mb/s) to UART/MPSSE IC. The device
features two interfaces that can be configured for asynchronous or synchronous serial or parallel FIFO
interfaces. The two channels can also be independently configured to use an MPSSE engine. This allows
the two ports of the FT2232H-56Q to operate independently as UART/Bit-Bang ports or MPSSE engines
used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes. All components used,
including the FT2232H-56Q are Pb-free (RoHS compliant).
The FT2232H-56Q Mini Module connects the signals of the FT2232H-56Q IC to two 26-pin dual-row
headers which allow easy connection PCB header sockets and ribbon cables.
The FT2232H-56Q Mini Module requires USB device drivers, available free from http://www.ftdichip.com,
which are used to make the FT2232H-56Q on the Mini Module appear as two 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 FT2232H-56Q on the Mini Module through a DLL. This is illustrated in Figure 1.2.

Table 3.2 FT2232H-56Q Mini Module Connection – CN3
In most cases, the FT2232H-56Q pin is connected directly to the associated pin on CN2 or CN3. The
FT2232H-56Q Mini Module allows configuration with both USB Bus-powered designs and USB Self-
powered designs:
USB Bus-powered:
1) JP1 is connected VBUS to VCC (CN3, pin 2 to CN3, pin 4). This connection takes the power
from the USB bus (VBUS) and connects it to the voltage regulator input on the FT2232H-56Q Mini
Module. The voltage regulator, in turn, provides V3V3, VPLL and VUSB power inputs to the
FT2232H-56Q chip.
2) JP2 is connected V3V3 to VIO (CN2, pins 2, 4 & 6 to CN2, pins 12 and CN3, pins 11 &
21). This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT2232H-
56Q chip.
3) Connected to jumper JP1 pin 1 in order to supply power for FT2232H-56Q chip from the USB
port.
4) External 3.3V regulator output. Connected to jumper JP2 pin 2 in order to supply the VIO voltage
with 3.3V tolerance.
USB Self-Powered:
1) Remove the JP1 and JP2 jumper.
2) Leave VBUS (CN3, pin 2) unconnected.
3) Connect an external 5.0VDC power supply to VCC (5.0VDC to CN3, pin 4). This
connection takes power from an external power supply and connects it to the voltage regulator
input on the FT2232H-56Q Mini Module. See the FT2232H data sheet for allowable VCC input
voltage ranges.
4) Connect V3V3 to VIO (CN2, pins 2, 4 & 6 to CN2, pins 12 and CN3, pins 11 & 21). This
connection provides the correct 3.3VDC operating voltage for VCCIO on the FT2232H-56Q chip.
5) Use FT_Prog 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.
FT_PROG is a utility provided by FTDI to program various features of the FT-series USB client ICs.
FT_PROG is available through the Utilities section of the FTDI web site.
