Version: **

 

Question:

Is there a power sequence required for different supplies such as VDDIO, VDDA, and VDDD in PSoC 3 and PSoC 5LP?

 

Answer:

No, there is no power sequence required. However, VDDA should be the highest supply in the system, and VDDA should be applied before other supplies or at the same time when other supplies are on.

Note: Do not apply VDDD before VDDA supply.
