6 MTP ROM Configuration
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 UMFT231XC are shown in Table 6.1.
Table 6.1 – 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

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 FT231XC 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.
Default configuration of CBUS0 – Drives low when a dedicated
charger port is connected the USB bus. Otherwise a floating
output pin.
Enables the use of BCD_Charger# function, allows for
BCD_Charger# to be driven low when a dedicated charger
port is connected.
Disables the option of forcing PWREN# to be driven low when
a dedicated charger port is connected.
Prevents SLEEP# pin from driving low when a dedicated
charger port is connected.
Default configuration of CBUS1 – Power enable (used to
switch SWPWR).
Default configuration of CBUS2 – Drives low when in USB
suspend mode. Configured to be disabled (ties high by
internal pull-up) when using a dedicated charger port.
Default configuration of CBUS3 – Power enable. Low after USB
enumeration, high when the FT231X is connected to a USB
host/hub and not enumerated. Configured to be disabled
(floating output) when a dedicated charger port is connected
to the device.
Inverts the UART signals.
