Internal MTP Memory Configuration
The FT230X includes an internal MTP memory which holds the USB configuration descriptors, other
configuration data for the chip and also user data areas. Following a power-on reset or a USB reset the
FT230X will scan its internal MTP memory and read the USB configuration descriptors stored there.
In many cases, the default values programmed into the MTP memory will be suitable and no re-
programming will be necessary. The defaults can be found in Section 8.1.
The MTP memory in the FT230X can be programmed over USB if the values need to be changed for a
particular application. Further details of this are provided from section 8.2 onwards.
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. See TN_100 – USB Vendor ID/Product ID
Guidelines for more details.
8.1 Default Values
The default factory programmed values of the internal MTP memory are shown in Table 8.1.

See Note
A unique serial number is generated and
programmed into the MTP memory during device
final test.
Enabling this option will make the device pull down
on the UART interface lines when in USB suspend
mode (PWREN# is high).
