Hi
I have some question about definition of ripple range.
It is defined 5% Vp-p of supply voltage average value in Hardware Development Guide.
If VDD_ARM_CAP average value is 1.27V, ripple spec allowed 1.238V( = 1.27x0.975) ~ 1.301V( = 1.27x1.025).
Is it correct?
If so,
Absolute maximum voltages of VDD_ARM_CAP is defined to 1.3V in Datasheet.
Is it OK that average value is 1.27V of VDD_ARM_CAP because average value is less than 1.3V?
Or is it NG because top of ripple voltage is over a 1.3V?
Best regards,
Ishii.

Hi Ishii
1.27V+-0.0635V (allowed 5%) should be within allowed by datasheet range.

Dear igor
Thank you for your quick reply.
How about Absolute Maximum Ratings.
Is it applies an average value (i.e. 1.27V)?
Or average value + ripple (1.27V + 0.0653)?
Best regards,
Ishii.
Hi Ishii
average value + ripple

Dear igor
Thank you for your quick response.
I understand a spec definition of datasheet.
Best regards,
