10.2 Methods of Programming the MTP Memory
10.2.1
The MTP memory on all FT-X devices can be programmed over USB. This method is the same as for the
EEPROM on other FTDI devices such as the FT232R. No additional hardware, connections or programming
voltages are required. The device is simply connected to the host computer in the same way that it would
be for normal applications, and the FT_Prog utility is used to set the required options and program the
device.
The FT_Prog utility is provided free-of-charge from the FTDI website, and can be found at the link below.
The user guide is also available at this link.

Additionally, D2XX commands can be used to program the MTP memory from within user applications.
For more information on the commands available, please see the D2XX Programmers Guide below.

10.2.2
In the FT200XD device, it is possible to program the MTP memory over its I
interface which is used in the normal application of the FT200XD and would normally be connected to the
I
used to access the MTP memory in the FT200XD over the same I
read and write locations in the MTP memory. No additional hardware, connections or programming
voltages are required.
