MSP430F6779A: How can I find supply currents value at 3.3 V?

Part Number: MSP430F6779A


I have seen MSP430F6779A's data sheet (SLAS982A) and also see "Using power solutions to extend battery life in MSP430™ MCU applications" (SLYT356A). From my point of view all of recommend supply currents in MSP430F6779A's data sheet might be increase in linearly as well as below figure from SLYT356A. Am I right?

Because I have problem about finding current consumption of MCU when it is supplied with 3.3 V of power supply. But entirely data sheet is specified in range of 3.0 V as below figure is from Active mode supply current in MSP430F6779A's data sheet.

The question is how can I find supply current @3.3V for this table and other tables in MSP430F6779A's data sheet?

Thank you.

    Hello Nattapol,

    As mentioned in another posting, yes, I would expect the current to be slightly higher than what is shown in the datasheet when operating at higher VCC.  Likewise with an increase in temperature.

    As suggested in the other posting, you will probably do best by characterizing a small number of samples.
