Future Technology Devices International Ltd, Unit 1, 2 Seaward Place, Centurion Business Park, Glasgow, G41 1HH, United Kingdom. Scotland Registered Number: SC136640 Copyright © 2012 Future Technology Devices International Limited Document Reference No.: FT_000115 FT4232H Mini Module USB Hi-Speed FT4232H Evaluation Module Datasheet Version 1.8 Clearance No.: FTDI#73 ` 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 VCP TTY USB Virtual COM Port DLL D2XX TTY USB One RXD Channel of USB Mini-B FT4232H Mini Module TXD Serial UART signals One RXD Channel of USB Mini-B FT4232H Mini Module TXD Serial UART signals Software application access to USB via D2XX Figure 1.2 Using the FT4232H Mini Module Device Drivers for the FT4232H Mini Module are available free from http://www.ftdichip.com.

The FT4232H Mini Module allows configuration with both USB Bus-powered designs and USB Selfpowered 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.

Yes Serial Number See Note Pull down I/O Pins in USB Suspend A unique serial number is generated and programmed into the EEPROM during device final test. Enabling this option will make the device pull down on the Disabled UART interface lines when the power is shut off (PWREN# is high). Manufacturer Name FTDI Product Description FT4232H_MM Max Bus Power Current 500mA Power Source Bus Powered Device Type FT4232 Returns USB 2.0 device description to the host. USB Version 0200 Note: The device is be a USB 2.0 Full Speed device (12Mb/s) as opposed to a USB 2.0 High Speed device (480Mb/s). Remote Wake Up Enabled High Current I/Os Enabled Load VCP Driver Disabled Taking RI# low will wake up the USB host controller from suspend. Enables the high drive level on the UART and CBUS I/O pins. Makes the device load the VCP driver interface for the device. Table 0.1 Default Internal EEPROM Configuration The EEPROM on the FT4232H Mini Module can be re-programmed over USB using the utility program MPROG. MPROG can be downloaded from the www.ftdichip.com. Version 3.5 or later is required for the FT4232H chip.
