Appendix A - Cable EEPROM Configuration
Each TTL-232RG 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 the following table
Parameter
Value
Notes
USB Vendor ID (VID)
0403h
FTDI default VID (hex)
USB Product UD (PID)
6001h
FTDI default PID (hex)
Serial Number Enabled?
Serial Number
Pull down I/O Pins in USB
Suspend
Yes
See Note
Disabled
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).
