BOOSTXL-TPS650861: BOOSTXL-TPS650861

Part Number: BOOSTXL-TPS650861
Other Parts Discussed in Thread: MSP430F5529, , TPS650861

Tool/software:

I want to use in-system programming but I cannot find anything that tells me what connector to use on my board so that I can use the flat cable from the BOOSTXL-TPS860851 module .  Can you provide the pinout and part number for the connector I need to put on my board?

Also, please verify that with in-system programming, only the cable from the BOOSTXL board should be connected, and no other power is needed.

    Hi Tom,

    The connector that the BOOSTXL-TPS860851 uses for the flat cable is Molex 052745-0633.
    This part may be obsolete, so similar FFC/FPC Connectors with 6 positions like Molex 0527450696 may be used.

    The pinout connections are shown below:

    Could you clarify what is meant by "only the cable from the BOOSTXL board"? Do you mean the same flat cable?

    Typically the BOOSTXL-TPS860851 board is powered by the USB input to the attached MSP430F5529 LaunchPad board.
    Are you using the MSP430 Launchpad in conjunction with the BOOSTXL board?

    Best Regards,

    Hello, Sarah,

    Thank you for the reply.  I had already found the J16 connector pinout that is on the BOOSTXL board itself, from the schematics for that board.  What I am looking for is the pinout on the other end.  In the "Description" on the TI page "https://www.ti.com/tool/BOOSTXL-TPS650861" it mentions that the BoosterPack "...includes a flat wire to enable programming of parts directly on customer board."  However, I cannot find out any information about that "flat wire."  Is it just a simple FFC flex cable, and do I need to put the same Molex FFC connector on my board as well?  Or does it have a socket so I can use standard headers?

    As for the power question, I understand that the BOOSTXL board is powered from USB.  I wanted to verify that I do not need to have my own board powered up, and that the VSYS provided from the BOOSTXL board is all that is needed to program the TPS650861 when it is soldered to my board but not being powered by anything else.

    Regards,

    Tom

    Hi Tom, 

    Thank you for the clarification, I see. I believe the description on the TI page may be misleading. 
    This flat wire connection is just a FFC flat cable, however using this is not the recommended method for customer programming. 

    In general, the BOOSTXL-TPS860851 board should be only used if you are intending to program a TPS860851 IC that is inserted into the socket itself.
    Are you attempting to program a TPS860851 in the socket, or a TPS860851 that is on your own custom board?

    If the latter, then the BOOSTXL board should not be necessary, as long as you are able to communicate to I2C directly on your own board.

    To program the TPS650861, All that is needed is a 7V supply applied to the CTL4 pin. On the BOOSTXL board, this is done with VSYS.
    No other power is needed.

    More details on the requirements for programming the TPS860851 can be found in the NVM Programming Guide.

    Let me know if you have further questions.

    Best Regards, 
    Sarah
