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

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.
Signal on this pin becomes TXD# if enable.
Signal on this pin becomes RXD# if enable.
Signal on this pin becomes RTS if enable.
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.
