Official Spy-bi-wire connector size and type?

Jtag have the 14pin dual-row 2.54mm pin header.

But is there a Official Spy-bi-wire Connector size and type?

What is prefered Production-Line Programming, using spybiwire. 
pads/through holes or pins?

    Yes: same connector, mos tpins uinused. Because the FET430UIF does 4.wire JTAG and SBW through the same cable and connector. If it is too large, feel free to make your own converter cable and use any connector you want (with at least 4 pins, including GND and VSense)

  • >Yes: same connector

    Way to big, I can not make the pcb twice as big to accommodate this large jtag connector.

    If I program often I put a micro-usb connector, I don't connect 5v pin as my curcuit can not handle more than 4.2v
    and if someone by mistake connect non modifed usb cable.

    But it's also shared with 4pin holes for production line programming., were 3.3v goes to mcu to only power it as curcuit have diode to not power up the rest of pcb.

    Come guys, new smaller spywire connector standard !

    You asked for an official connector, not for one that suits your needs :) With the proper adaptor, any connector of your choice is fine. But the 14 pin header is the only official one. For both, SBW and 4-wire.

  • With that kind of thinking our cell-phones will use USB-B connectors today.

    I'm asking TI, to come up with a new smaller standard.

    Ti could jsut define the signals and not recommend any header at all.
    The fact that the 14 pin is the only standard, means that you won't see a FET with anything else as connector, adn if you use it, you
    'll be able to connect any FET to any board without need of an adaptor.
    However, nobody keeps you from using any conenctor type you want, from free wires (not really recommended) over test points, micro-USB connectors (also not recommended as surely someone will put a real USB cable into it sooner or later) or whatever.

    What you currently do is to tell TI the should define a connector that fits to your personal purposes better, build it into their devices and support it.

    Besides this, it makes no sense to change standards every day. A new 'standard of the day' each day isn't better than no standard at all.

  • I made a 14pin-dual-row to micro-usb cable, but connecting round cables to a connector made for ribbon type is never a good look.

    So if future MSP-FET430UIF have a second port for just spy-bi-wire.
    USB-A to Micro-USB maybe?, though accidental 5v from a usb charger is not good.
    Though I could make IDpin the 3.3v sense/source and if users pcb need and can handle 5v he/she connects theVbus trace.

    But a team at TI, should be able to determine the best type of connector.

    Sure, I could try to start a trend and see where it goes.

     

     

  • Most people just make an adaptor. Most recently (for 4-wire JTAG plus GND, Vsense, TEST, and RST) I used a ZIF socket  on the target and an adaptor like this:

    Works perfectly.

  • They created a straight 1.27mm pitch pin header standard for their eZ430 series.

    Example: http://processors.wiki.ti.com/index.php/EZ430-RF2500

    The MSP430 LaunchPad has this header on its right side unpopulated (you need to buy the requisite right-angle header for it).  I personally have built a board that mounts overtop the MSP430 LaunchPad v1.5's 2.54mm pitch SBW header, but in retrospect using the eZ430 pinout would have worked too.  It's probably closer to what you're thinking.

    See page 10 of SLAU227 - http://www.ti.com/lit/ug/slau227e/slau227e.pdf

    Just be sure NOT to plug it in upside down--the Vcc and GND pins are in symmetric locations, so flip-flopping them will result in a bad situation (inverse voltage).

    I saw another eZ430 board (F2013?) had a 4-pin version of that, and it appears the 6-pin version is designed to be fully compatible; the 4-pin variant just has the inner 4 pins for Vcc, GND and SBW only, while the 6-pin variant adds UART to the outer pins.

    You are comparing apples to oranges. USB is consumer-designated connector, JTAG and other similar kind of connectors are not.

    If you want standard, then you shall talk to IEEE instead.

    Or just pads or unpopulated thru-holes on board. That's the beauty of your connector which shall be used only by your engineers or manufacturers - you are free from standards and manufacturers of connectors :D
