Small JTAG Header - abufadel - Sep 10 0:28:02 2008
Greetings,
I am trying to minimize the size of my board as much as possible.
All the real msp430 programmers have rather large jtag connectors. I
read in a previous post that the ez430 usb stick (which allows for a
small connector for programming) is not an ideal programming solution.
Any ideas?
Thank you,
A

make an adapter to go from one of the 'real' programmers to smaller
connector that you choose for your design.

for details on SPW pin connections go through the FET user guide.

Not all micros will take the 2 pin interface (4 with power/gnd), but for
those that do I have experienced no serious issues at all, so don't know
why you might think it not suited.
Ever since I started wit the MSp430 some 10 years ago I have never used
their IDEC connector, rather I make up a small adapter cable. Typically
this has a 14 pin IDC at the JTAG end and in the first boards a 6 pin
1.25mm spaced Hirose/harwin header at the other. More recently I have
switched to a GradConn 1mm spaced connector. I also often use an 8 pin
these days to accomodate the TEST/Vpp function to blow the jtag fuse,
and to provide external Vcc.
here's a neat idea too, for some boards I use 0.2mm, 0.1mm or even flex
PCB. In these cases I create a finger type edge connector on part of
trhe PCB and plug the board into a vertical mount FPC connecor. just
watch the maximum PCB thickness for the PCB end of this.
Finally go to my images on the group site where I have an example of a
snap off connector scheme that I use for programming and development.
Once this stage is finished the PCB has a series of small vias on the
main board that allow bedof nails bulk programming or in field updates
with a simple sprung alligator clip adaptor.

A good solution is to have the minimum number of connections to pads that
are contacted by spring-loaded pins.

A,
We have a couple of off-the-shelf smaller programming adapters that
help solve this problem. One is for the 14-pin format to an 8-pin flex
cable:
http://www.softbaugh.com/ProductPage.cfm?strPartNo=JFPC
And the other is for a 4-pin SpyBiWire:
http://www.softbaugh.com/ProductPage.cfm?strPartNo=PASBW
Both are compatible with all 14-pin programmers, such as our
USBP/USBPPRO:
