Appendix A – FT4232H EEPROM Configuration
The FT4232H Mini 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.

Table 6.1 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. 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. Contact FTDI support for this
service.

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 High 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.
