Table 8.1 Default Internal MTP Memory Configuration
8.2 Methods of Programming the MTP Memory
8.2.1 Programming the MTP memory over USB
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. Note that the FT-X devices require FT_Prog version 2.5 or
later.

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.

Notes
Options are normal or Schmitt
Options are 4mA, 8mA, 12mA, 16mA
Options are slow or fast
Options are normal or Schmitt
Enables the high drive level on the FIFO data bus
and control I/O pins.
Enabling this will load the VCP driver interface for
the device.
Used to detect when the device is connected to a
USB host and power is available.
Prevents the device from entering suspend state
when unplugged.
