Appendix A – FT4232H EEPROM Configuration
The USB Hi-Speed Serial/Hub Module utilizes an EEPROM which contains the USB configuration
descriptors for the FT4232H. When the Mini Module is plugged into a PC or a USB reset is performed, the
PC will read these descriptors. The default values stored into the EEPROM are defined in Table 6.1.

The EEPROM for FT4232H chip on the USB Hi-Speed Serial/Hub Module can be re-programmed over USB
using the utility program FT_Prog. FT_Prog can be downloaded from
http://www.ftdichip.com/Support/Utilities.htm. Users who do not have their own USB Vendor ID but who
would like to use a unique Product ID in their design can apply to FTDI for a free block of unique PIDs.

Notes
FTDI default VID (hex)
FTDI default PID (hex)
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
UART interface lines when the power is shut off (PWREN#
is high).
Returns USB 2.0 device description to the host.
Note: The device is be a USB 2.0 Full Speed device
(12Mb/s) as opposed to a USB 2.0 Hi-Speed device
(480Mb/s).
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.
