I have an microcontroller. MSP430FR2310.
I am supposed to interface this microcontroller with a temperature sensor (TMP100)and Level translator (3.3V to 1.8v).
I have selected the chips. I am asked to do power calculations for this system.
How should I do it ?
Should I just take in the supply voltage of each chip and multiply with the load current?
I googled this.
But it doesn't seem that simple to just multiply the voltage and current.
It seems that we have to calculate the current at each pin of the peripheral device ( TMP100) and then take the total current and multiply it with the supply voltage?
Can someone explain it clearly in step by step process with an example on how should my calculation look?
Please.
