Does not TMS320F28377D have EMU0,EMU1 pins?

Other Parts Discussed in Thread: TMS320F28377D

Hello,

In the Pin description of TMS320F28377D Datasheet, EMU0/EMU1 pin of JTAG Signal is missing.

I can`t find it. But F28377D ControlCard`s schematics has included them.

 

Does EMU pins add to next revision?

    Hi,

    If you might've noticed correctly, these pins have been emulated on the control card. Here's the schematic:

    Hello,

    Like many members of the Piccolo family, the F2837xD family of MCUs do not have EMU0/EMU1 pins.  We will not add these in a future revision to this device.

    ---

    I agree that this is unclear in the schematic and will make a note to improve this.

    In general: A:U3 & A:U11 are unnecessary for F2837xD devices.


    Thank you,
    Brett

    Thank you for answer, Brett.

    And Gautam,too.

     

    I have any other question. About a Crystal value.

    In Silicon Errata,

     

    But F28377D ControlCARD has 20MHz Crystal in schematic. And, real board too. 

    Which one is right?

    Of course ControlCARD is good acting, no problem.

    Sang-Hyeon,

    The errata takes precedence.  

    From a practical perspective, you probably won't run into any issues using the control card to evaluate the F2837xD device; we aren't saying that it definitely won't work, just that there is a possibility it could fail under some worst case conditions.  If you want to start qualifying a design using the F2837xD, you should follow the errata guidance to make sure it works every time, under all possible operating conditions.

    Hi, I’m recently designing a minimum system board of F28377D, and have the same question. the Control Card schematic confuses me.

    I still cant figure out what should I do if A:U3 & A:U11 are are unecessary.

    Since F28377D dosen‘t have EMU0/1 pins,  to where should I connect the Pin 13 &14 of the JTAG header ?or should them be left unconnected?

    Hi Ran Gao,

    Please don't post in a existing thread even if the topic seems similar. Always create a new post! Anyways,

    Ran Gao,

    In your case, pin 13 and pin 14 of your JTAG header should each be pulled-high with a 4.7Kohm resistor.


    Thank you,
