Appendix A - Cable EEPROM Configuration
Each C232HD cable is controlled by the FTDI FT232H IC. This cable 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 the following table

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 a the Product descriptions for each different cable.
C232HD-DDHSP-0
C232HD-EDHSP-0
Includes power to operate the FT232H plus the cable
output current.
Returns USB 2.0 device description to the host.
Note: The device is a USB 2.0 Hi-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.
