Hi,
On my board VDDA_3V3 is powered from 3.3V and VDDIO is powered from 1.8V.
According to the DS there is power up sequence requirement and my board complies.
As for the power down sequence there is no mention nor requirement.
On my board there is a case where during power down VDDA3V3 will remain powered while VDDIO is removed for unlimited time.
Is this applicable? Is this safe operating condition for the device?
Can you clarify this issue and get back with answer please?
Thanks,
Erez.
