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,

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, I
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
