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.
VNC2 has the following advanced features:
Embedded processor core

16 bit Harvard architecture

Two full-speed or low-speed USB 2.0

interfaces capable of host or slave
functions
256kbytes on-chip E-Flash Memory

(128k x 16-bits)
16kbytes on-chip Data RAM (4k x 32-

bits
Programmable UART up to 6Mbaud

Two SPI (Serial Peripheral) slave

interfaces and one SPI master
interface
Reduced power modes capability

Variable instruction length

Native support for 8, 16 and 32 bit

data types
Use of FTDI devices in life support and/or safety applications is entirely at the user's risk, and the user agrees to
defend, indemnify and hold harmless FTDI from any and all damages, claims, suits or expense resulting from such
use.
