V2DIP1-64 VNCL2-64Q Development Module Datasheet Version 1.0
Clearance No.: FTDI# 154
1 Introduction
V2DIP1-64 module is designed to allow rapid development of designs using the VNC2-64Q IC. The
V2DIP1-64 is supplied as a PCB designed to fit into a 60 pin 0.8” wide 0.1” pitch DIP socket.The module
provides access to the UART, parallel FIFO, and SPI interface pins of the VNC2-64Q device, via its IO bus
pins. One USB port is accessed via a type A USB connector.
Figure 1.1 - V2DIP1 64
The VNC2 is the second of FTDI’s Vinculum family of Embedded dual USB host controller devices. The
VNC2 device provides USB Host interfacing capability for a variety of different USB device classes
including support for BOMS (bulk only mass storage), Printer, HID (human interface devices). For mass
storage devices such as USB Flash drives, VNC2 also transparently handles the FAT file structure.
Communication with non USB devices such as a low cost microcontroller is accomplished via either UART,
SPI or parallel FIFO interfaces. The VNC2 provides a new cost effective solution for providing USB Host
capability into products that previously did not have the hardware resources available.
The VNC2 supports the capability to enable customers to develop custom firmware using the Vinculum II
development software tool suite. The development tools support compiler, linker and debugger tools
complete within an integrated development environment (IDE).
The Vinculum-II VNC2 family of devices are available in Pb-free (RoHS compliant) 32-lead LQFP, 32-lead
QFN, 48-lead LQFP, 48-lead QFN, 64-Lead lQFP and 64-lead QFN packages

3.4 UART Interface
When the data and control buses are configured in UART mode, the interface implements a standard
asynchronous serial UART port with flow control. The UART can support baud rates from 300baud to
3Mbaud. Further details on the UART interface are available on the the Vinculum-II datasheet please
refer to:- FTDI website
3.4.1 Signal Description – UART Interface
The UART signals can be programmed to a choice of available I/O pins. Table 3.3 explains the available

Table 3.7 - Asynchronous FIFO Mode Read Cycle Timing
In asynchronous mode an external device can control data transfer driving FIFO_WR# and FIFO_RD#
inputs. In contrast to synchronous mode, in asynchronous mode the 245 FIFO module generates the
output enable EN# signal. EN# signal is effectively the read signal RD#.
Current byte is available to be read when FIFO_RD# goes low. When FIFO_RD# goes high, FIFO_RXF#
output will also go high. It will only become low again when there is another byte to read.
When FIFO_WR# goes low FIFO_TXE# flag will always go high. FIFO_TXE# goes low again only when
there is still space for data to be written in to the module.

Table 3.9 - Synchronous FIFO Mode Read and Write Cycle Timing
In synchronous mode data can be transmitted to and from the FIFO module on each clock edge. An
external device synchronises to the CLKOUT output and it also has access to the output enable OE# input
to control data flow. An external device should drive output enable OE# low before pulling RD# line
down.
When bursts of data are to be read from the module RD# should be kept low. RXF# remains low when
there is still data to be read. Similarly when bursts of data are to be written to the module WR# should
be kept low. TXE# remains low when there is still space available for the data to be written

3.8 Debugger Interface
The purpose of the debugger interface is to provide access to the VNC2 silicon/firmware debugger. The
debug interface can be accessed via the appropriate pin on the DIL connector or more easily, it can be
accessed by connecting a debug module to the J3 connector. This debug module will give access to the
debugger through a USB connection to a PC via the Integrated Development Environment (IDE). The IDE
is a graphical interface to the VNC2 software development tool-chain and gives the following debug
capabilities through the debugger interface:
Flash Erase, Write and Program.
Application debug - application code can have breakpoints, be single stepped and can be halted.
Detailed internal debug - memory and register read/write access.
The Debugger Interface, and how to use it, is further described in the following applications Note
