Hello,
On the datasheet stated that "There is no requirement for the sequence of the supplies when operating in two-supply mode."
Our customer tried to validate behavior if power up VDD1P0 at first and later on power up VDDIO & VDDA2P5.
What they have captuerd was that 200mV potential on VDDIO pin. It seems caused by internal leakage current from VDD1P0.
Is this expected behavior on this device and still no problem of sequence free power up function?
Regards,
