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.

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.

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.
