Appendix A – FT232R EEPROM Configuration
This FT232R device within the UB232R module contains an EEPROM which contains the USB configuration
descriptors for that device. When the UB232R is plugged into a PC or a USB reset is performed, the PC
will read these descriptors. The default values stored into the internal EEPROM are defined in Table 6.1
Parameter
Value
Notes
USB Vendor ID (VID)
0403h
FTDI default VID (hex)
USB Product UD (PID)
6001h
FTDI default PID (hex)
Serial Number Enabled?
Yes
Serial Number
See Note
A unique serial number is generated and programmed into
the EEPROM during device final test.
Pull down I/O Pins in USB
Suspend
Disabled
Enabling this option will make the device pull down on the
UART interface lines when the power is shut off (PWREN#
is high).

Disabled
Signal on this pin becomes CTS if enable.
Table 6.1 Default Internal EEPROM Configuration
The internal EEPROM in the FT232R can be re-programmed over USB using the utility program FT_PROG.
FT_PROG can be downloaded from the www.ftdichip.com. 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.
