tiva 129x current consumption

Hi,

I wish to use TMC129x processor for my application. But however i would lie to know the  power consumption and current consumption of the processor for building the hardware.

Regards,

Dhanush

    The current consumption power number for TM4C129X series is already there in the data sheet. The power consumption would be maths after that.

    @Amit,
     
    May I applaud your directing poster to a, "basic read" of a rather detailed MCU data manual?  Too often - such effort-free/lite posts are detail-answered by forum staff - which myself/others believe encourages further poster "inaction."
     
    In some cases - data may not be fully available.  (i.e. marked as tbd)  Smart posters likely note this - adding legitimacy to their request.
     
    Current draw is influenced by several MCU variables - fully under the user's control.  These may include: frequency of MCU System Clock, number of peripherals active/enabled, and time spent in operation vs. "sleep/deep-sleep."  As the system board becomes more populated - other components add to the total current/power budget.
     
    Much (perhaps all) of this detail emerges upon serious read of the MCU data manual.  (and that of any accessory components, as well...)

    Thanks cb1_mobile for the note. I should have been more specific on some of the data considering the details in the datasheet.

    @Dhanush

    You may want to look at the Current Consumption Chapter of the Electrical Characteristics Section of the Datasheet. Specifically the table which lists the IDD_RUN.

    Please note that the current numbers mentioned there are for All Peripherals ON and OFF with a while 1 execution.
