7 Internal MTPROM Configuration
Following a power-on reset or a USB reset the FT230X 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
FT230XQ used on the UMFT230XA are shown in Table 8.1.

Serial Number
See Note
A unique serial number is generated and programmed into
the, TP ROM during final test of the module.
Pull down I/O Pins in USB
Suspend
Disabled
Enabling this option will make the device pull down on the
UART interface lines when the power is shut off (PWREN#
is high).

Table 7.1 – Default Internal MTP ROM Configuration
The internal MTP ROM in the FT230X 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 des ign can apply to FTDI for a free block of
unique PIDs. Contact FTDI Support ([e-mail]) for this service , also see TN_100 and
TN_101.
