Hi,
The datasheet (https://www.renesas.com/us/en/document/dst/upd720201upd720202-data-sheet) states
"It is recommended that the time difference between the start of power-supply rise (3.3V or 1.05V) and the point where both power supplies are stabilized should be within 100ms, regardless of the order of power source."
While below this statement there's a Figure 3-1 showing 3.3V rising/falling prior to 1.05V in both the on and off sequence.
It's a bit unclear to me whether I can power up with 1.1V first then 3.3V, as long as the 100ms stabling period is met?
From the written statement it seems so, however I'd like to confirm my understanding is correct.
Thanks and looking forward to any feedback,
Ayo
