Following a power-on reset or a USB reset the FT231X 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
FT231XQ used on the UMFT231XE are shown in Table 8.1.

Table 8.1 – Default Internal MTP ROM Configuration
The internal MTP ROM in the FT231X can be 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

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 UM232R 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) 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 CVP driver interface for the
device.
Signal on this pin becomes TXD# if enable.
