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.
