Vinculum-II
Embedded Dual USB Host
Controller IC
Vinculum-II is FTDI’s 2nd generation of USB Host
device. The CPU has been upgraded from the
previous VNC1L device, dramatically increasing the
processing power. The IC architecture has been
designed to take care of most of the general USB
data transfers, thus freeing up processing power
for user applications. Flash and RAM memory have
been increased providing larger user areas of
memory for the designer to incorporate his own
code. The designers also have the ability to create
their own firmware using the new suite of software
development tools.
