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 free ing 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

(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


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
