Vinculum-II Embedded
Dual USB Host Controller
IC
Vinculum-II is FTDI‟s 2nd generation of USB Host
devices. 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 has
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 3Mbaud.
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,
FIFO interface or USB Flash Drive.
12MHz oscillator using external crystal.
General-purpose timers..
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
VNC2-48L1A 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.
+3.3 volt supply.
-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.
