However, it is not limited to this application. It can also be used as a hub device or an FT4232H evaluation module. The module has a USB 2.0 Hi-Speed hub chip which supports up to three external downstream USB ports: 2 via a dual USB connector and 1 via the DIL connector pins. Aditionally, by utilizing the FT4232H USB Hi-Speed four-port bridge chip which handles all the USB signalling and protocols, the module can easily support up to 4 flexible interfacing ports. It is ideal for development purposes to quickly prove functionality of adding USB to a target design. Figure 1.1 - FT4232H Serial/Hub Module The module utilises the GL850G USB 2.0 hub controller which provides a low-cost, and widely used USB 2.0 hub solution, to provide up to 4 downstream USB ports. The GL850G is a single USB hub solution. The GL850G is a full function solution which support both Individual/Gang power management modes and two-color (green/amber) status LED. GL850G can be used with an external EEPROM (on the module) which can be used to customize PID/VID and other more complicated settings. The FT4232H used on the Module is FTDI’s 5th generation of USB devices. The FT4232H is a USB 2.0 HiSpeed (480Mb/s) to UART/MPSSE IC. The device features four interfaces that can be configured for asynchronous or synchronous serial communications. Two of these interfaces have an option to be independently configured via an MPSSE engine. This allows the FT4232H to operate as two UART/BitBang ports plus two MPSSE engines which can be used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes. The FT4232H datasheet, DS_FT4232H, is available at http://ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT4232H.pdf The block diagram of FT4232H Hub Module is shown in Figure 1.2.

This allows easy connection to most PCB header sockets and ribbon cables. To reduce the connector pin count, only channel A and B fan out all the 8 data signals to the 18-pin header. For the channel C and channel D, since many designs only use the TXD/RXD/CTS/RTS signals in UART communication, only these 4 data signals are fanned out. This meets most application requirements. To use the FT4232H connected to a PC , the FT4232H Hub Module requires specific USB device drivers, available free from http://www.ftdichip.com. The drivers are used to make the FT4232H on the 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. The main target application for the USB hi-Speed Serial/Hub Module is that it can be attached to the FTDI VNC2 based V2DIPx modules (there are 6 different sizes) as a expansion module. By connecting the USB Hi-Speed Serial/Hub Module to the USB socket on the V2DIPx modules, the two modules can work as a single module to be placed on the bread board. The USB Hi-Speed Serial/Hub Module expands the interfaces of V2DIPx module with up to 3 USB ports and 4 serial ports. More information is available on the V2DIPx modules at http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm. 1.1 Part Numbers Part Number Description FT-MOD-4232HUB USB Hi-Speed_Serial/Hub_Module Copyright © Future Technology Devices International Limited 2 ` Document Reference No.: FT_000331 USB Hi-Speed Serial/Hub Module Version 1.4 Clearance No.: FTDI# 174 Table of Contents 1 Introduction............................................................................................ 1 1.1 2 3 Part Numbers ....................................................................................................... 2 Typical Applications .............................................................................. 4 2.1 Features ............................................................................................................... 4 2.2 Driver Support ..................................................................................................... 4 Electrical Details .................................................................................... 5 3.1 Power Supply of FT4232H Hub Module ............................................................. 8 4 Mechanical details ................................................................................. 9 5 Schematic Diagram ............................................................................. 10 6 Contact Information............................................................................. 12 Appendix A – FT4232H EEPROM Configuration........................................................ 10 Appendix B – List of Figures and Tables ................................................................... 11 List of Figures............................................................................................................... 11 List of Tables ................................................................................................................ 11 Appendix C – Revision History ................................................................................... 12 Copyright © Future Technology Devices International Limited 3 Document Reference No.: FT_000331 USB Hi-Speed Serial/Hub Module Version 1.4 Clearance No.: FTDI# 174 ` 2 Typical Applications  Expansion module for the FTDI V2DIPx modules to expand usb ports and interfaces.  Rapid USB integration into existing electronic systems.  Prototyping platform for USB interface on new systems.  USB 2.0 hub device to support up to 3 downstream USB ports.  USB to muli-port JTAG, SPI and I2C interfaces (Two Multi-Protocol Synchronous Serial Engines – MPSSE – available with the FT4232H)  USB to multi-port asynchronous serial interfaces (up to 4 ports available). 2.1 Features The USB Hi-Speed Serial/Hub Module has the following features: General:  USB 2.0 Hi-Speed compatible  Defaults to 4 RS232 interfaces.  One standard Type A USB header to connect to the Host  Asynchronous Serial data transfer rates from 300 baud to 12 Mbaud at TTL levels  USB Hi-Speed FT4232H device for USBSerial/Bitbang communications.

The estimated current consumed by the cirucuits of module is about 100-300mA depending on the application. It is important that the user ensures that the host can supply this current via USB. The maximum total current consumed by the external usb devices on downstream port 2 and 3 is 1A. If the total current exceed 1A, the fuse on the USB Hi-Speed Serial/Hub Module will be disconnected. If this occurs then LEDs D2 and D5 on the module will illuminate to indicate over-current status. There are two options to supply power to external downstream usb devices connected to ports 2 and 3. 1. Use USB bus power to supply downstream ports: Connect 5V to VCC_BUS (CN3, pin 3 to CN3, pin 2). This connection uses the power from upstream USB bus to supply the downstream USB ports of the USB hub. With this connection, user should make sure that the usb host can supply enough current to the external USB devices – in addition to the current required by the module. 2. Use external power to supply downstream ports: Connect 5V (CN3, pin 3) to external +5v DC power supply. This connection takes the power from external power to supply the downstream USB ports of USB hub. Users should also make sure that the external power can supply enough current required by the external devices. Note: 1. In USB bus power mode always ensure that CN3-pin 2 (VCC_BUS) and CN3-pin 3 (5V) are shorted together. In external power mode pins CN3-2 and CN3-3 should be disconneted and external power supply should be connected to pin CN3-3 only. 2. It is recommened to select the mode of operation before connecting the USB Hi-Speed Serial/Hub Module.
