## Power consumption in CY27410

How should I calculate the power consumption? Is there a spreadsheet that can be calculated?

The data sheet have IDDs. However, the number of descriptions is small and the conditions are quite limited.

Thanks,
Tetsuo

Do Iddpm need to be considered? In my opinion, Itot is expressed by the following equation.

Itot = Iddo + Iddpm

And in the data sheet, there is no mention of frequency other than CMOS. I want to use a differential output(LVDS). Is Iddo frequency dependent when using differential outputs?

You can refer to our knowledge base article as below which also contains the formulas for calculation the power dissipation.

Is the "IDDO" in the CY27410 datasheet Idc or Iac? If it is equivalent to Itot, should I just look at IDDO?

IDDO will be the total current.
