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.
