8 Internal MTP ROM Configuration
Following a power-on reset or a USB reset the FT234XD will scan its internal MTP ROM and read the USB
configuration descriptors stored there. The default values programmed into the internal MTP ROM in the
FT234XD used on the UMFT234XD are shown in Table 8.1.

Notes
FTDI default VID (hex)
FTDI default PID (hex)
A unique serial number is generated and programmed into
the MTP ROM during final test of the UMFT234XD module.
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 a USB 2.0 Full Speed device (12Mb/s).
Taking RI# low will wake up the USB host controller from
suspend.
Enables the high drive level on the serial and CBUS I/O
pins.
Makes the device load the VCP driver interface for the
device.
The internal MTP ROM in the FT234XD can be programmed over USB using the utility program FT_PROG.
FT_PROG can be downloaded from 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 ([e-mail]) for this service.
