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
Eight bit wide FIFO Interface
Firmware upgrades via UART, SPI, and
FIFO interface
12MHz oscillator using external crystal
General-purpose timers
+3.3V single supply operation with 5V
safe inputs
Software development suite of tools to
create customised firmware. Compiler
Linker –Debugger –IDE
Available in six RoHS compliant
packages - 32 LQFP, 32 QFN, 48 LQFP,
48 QFN, 64 LQFP and 64 QFN
VNC2-48L1 package option compatible
with VNC1L-1A
44 configurable I/O pins on the 64 pin
device, 28 I/O pins on the 48 pin
device and 12 I/O on the 32 pin device
using the I/O multiplexer
-40°C to +85°C extended operating
temperature range
Simultaneous multiple file access on
BOMS devices
Eight Pulse Width Modulation outputs
to allow connectivity with motor
control applications
Debugger interface module
System Suspend Modes
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.

3.12 Pin Configuration Input / Output
VNC2 has multiple interfaces available for connecting to external devices. These are UART, FIFO, SPI
slave, SPI master, GPIO and PWM. The Interface I/O Multiplexer is used to share the available I/O Pins
between each peripheral.
VNC2 is configured with default settings for the I/O pins however they can be easily changed to suit the
needs of a designer. This is explained in Section 5 –I/O Multiplexer. Default configuration for each
package type is shown in Table 3.4- Default I/O Configuration. The signal names are also indicated
for the VNC1L device as it is pin-compatible with the 48 pin LQFP VNC2 device.
Note: The default value of the pins listed in the following table are only available when the I/O
Mux is enabled. A blank VNC2 chip defaults to all I/O pins as inputs.
