Appendix A - Cable EEPROM Configuration
Each TTL-232R cable is controlled by the FTDI FT232R IC. This FT232R device contains an EEPROM which
contains the USB configuration descriptors for that device. When the cable 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 0.1

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).
Product description depends on the cable. The following
lists the Product description for each different cable.

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).
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.
