New ContributorCyclone V VCCIO increases when VCCPD is applied
Hi,
Our VCCIO is 1.25V and applied before VCCPD is applied
When VCCPD (2.5V as requested by the datasheet) is applied VCCIO increases by 50mV
Is this normal behaviour ?
My device is : 5CEFA...

Regular ContributorHello,
Do you refer to the Pin Connection Guideline and Power Sequence documentation in your design?
You can refer here:
