Using USB programming tool for bare MCUs

I know this may be a weird question but I'm just hoping someone has a solution. I want to buy some F2012 MCUs and program them using the ez430 USB dev tool I have. The target board is pretty simple from what I've seen so this should not be a problem. The problem I have is getting the right signals from the ez430 tool.

I looked at the TPx pins exposed on the tool but they don't seem to offer the needed SBWTCK and SBWTDIO signals. So, the only other alternative I thought about is to use the small connector on the USB tool. The problem is that I don't want to bend the pins and I can't find a matching female connector so small (as the one on the target boards). Does anyone have any idea of how I can accomplish prohgramming a bare MCU using the USB tool?

Thanks a lot in advance for any ideas.

    You can get the mating connector from DigiKey. I do not remember the part  number. It comes in a long strip any you cut it yourself.

    You can also buy F2012 target boards from TI. 3 boards for $20 is well worth it!

    Awesome! Thank you so much, I had no idea about the connector being on Digikey, I'll search for it.

    About the target boards: this is my plan for now, I am just getting ready to order a few of them and use them in my project without having to mess with weird connectors. However, for the future I was thinking to try to use the F2012 directly, I found it for sale for $1.88 each while the target boards are almost double in price so the final price would be lower.

    But overall, I totally agree with you: the target boards have the integrated LED and they are definitely worth a lot more than messing with the processor directly.

    Thanks again.

    the manufacturer part numbers for the eZ430 headers are listed in the FAQ of the tool user guide.  

    for small prototypes, i usually order them from mouser.  the headers are hard to find in 4- or 6-pin lengths, but strips of 50-pin are much easier to get a hold of.  it's pretty simple to snap off the length that you need.

    here are the parts you need:

    from mouser catalog:

    Great, thanks a lot for the info, adrian, I was not able to find it at Digikey so this helps a lot!

    Not to nitpick but I thought it was 3 F2012 target boards for $10 or $20 for the EZ430-F2013 dev kit.[:)]
