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.
