The examples posted on this
page demonstrate the use of the FTDIChip-IDô feature of the
devices. The FTDIChip-IDô is a permanent, unique number programmed
into each IC during production that cannot be changed by the end user.
Since each number is unique, applications can be tied to specific
devices, providing a dongle feature. The
USB-Key is ideal for developers wishing to
utilise only the FTDIChip-IDô security features without a UART or FIFO
An application note is available on the FTDIChip-IDô on our
Notes page. In order to extract the FTDIChip-IDô from a
device, the FTChipID DLL is required and
D2XX drivers must be installed.
The FTChipID DLL is available for
Linux (V0.1.0) and
Mac OS X (V0.1.0). A FTChipID programmer's guide is
available from our
Programming Guides page.
Example code showing how to use the FTChipID DLL is available for the
