1 Introduction
The following data sheet details the features and specifications of the VNC2 debug module. The VNC2
debug module is designed to provide connectivity between the Vinculum-II IDE development software
and the debug interface pin on the FTDI Vinculum-II (VNC2) USB host controller device.
The VNC2 debug module consists of a miniature board with a USB miniB connector, which provides USB
connectivity to Vinculum-II IDE development tools running on a PC. The VNC2 debug module can be
used to program and debug firmware running on the VNC2 device.
The module connects to the VNC2 device via a 6-way, 2mm pitch, keyed, female connector. The V2DIPx-
x, VNC2 based development modules are equipped with a compatible male connector to host the VNC2
debug module. Designers intending to use the module with their own VNC2 based hardware are required
to have a similar compatible male connector on their hardware. Details on the debug interface and
connectors are outlined in subsequent sections of this document.

3.4 Connecting Debug Module on V2DIPx-x Modules
The V2DIPx-x modules have a compatible 6-pin, 2mm pitch male connector for directly connecting the
VNC2 debug module to the V2DIPx-x board.
Figure 3.2 Example Connection of Debug Module Connection to V2DIP2-64
3.5 Connecting Debug Module on Custom PCB
Where a customer is developing their own VNC2 based hardware, customers can support the VNC2 debug
module connectivity by hosting a compatible connector on their PCB. The VNC2 debug module requires a
6-pin, 2mm pitch male connector providing connectivity to the VNC2 debug pin, PROG# and RESET# pins,
as well as GND and VCC pins. Details on the required connectivity are shown on
Figure 3.3.
A Samtec connector, part number TMM-106-01-G-S-RA, has been used as the mating male connector for
the debug module on the V2DIPx-x modules. Similiar connectors are available from other vendors.
Figure 3.3 VNC2 Debug Module Interfaced To VNC2 Custom Application
Notes:
Debug pin: By default the VNC2 debug pin is mapped to IOBUS0 pin on the VNC2. However
the debug pin can be relocated to altering the IOMUX multiplexer settings for the device in a
user application. Designers are advised to check the configuration of the debug pin prior to
connecting the VNC2 debug pin to their board.
VCC +5V Supply: Optional requirement for the debug interface. +5V supplied from the USB
interface via connector CN1. Can be used to supply up to 400mA to an external circuit on the
mating board.

3.6 Confirm Debug Connection Using IDE
Having connected the VNC2 debug module to the VNC2 hardware, a user can verify the operation of the
debug interface operation using the Vinculum II IDE development software.
Simply connect the debug module to a PC via the mini-B USB connector. Open the Vinculum II IDE
software. Under the ‘Debug’ tab the ‘VII Debugger Module’ should be listed as an available debug
interface. Once detected, users can now use the VNC2 debug module to debug code and program the
VNC2 device.
