Part Number: CDCM6208V1F

Hi all

Would you mind if we ask CDCM6208V1F?

Our customer will use CDCM6208V1F with Y0 and Y6 only.
And the customer would like to reduce power consumption.

<Question1>
Is it possible to power off VDD_Y2_Y3, VDD_Y4, VDD_Y5, and VDD_Y7?

<Question2>
In relation to <Question1>, compared with the condition power on and each disable the outputs,
does power off VDD_Y2_Y3, VDD_Y4, VDD_Y5, and VDD_Y7 improve consumption?
It assumes that it only contributes reducing of leakage current.

<Question3>

When <Question1> and <Question2> are not problem, which is followings good for reliabitiy?
-power off VDD_Y2_Y3, VDD_Y4, VDD_Y5, and VDD_Y7
-power on and each disable the outputs

Kind regards,
