STM32F030 datasheet: Misleading VDDA vs VDD sequencing description?

Split from: Power Supply for STM32F030 Cortex TSSOP20 VDDA and VDD pin; specifically this post.

that satisfies the condition. 


But only the "VDDA >= VDD" condition - it doesn't satisfy the "VDDA must be first" condition. 

As noted, I suspect that the 2nd condition is incorrectly stated; I guess it should say, "VDD must not come after VDDA" or similar ?

That is the most common configuration.


Indeed it is!

@fredy - you could check out some ST board schematics to verify ...

    @mƎALLEm  Can the misleading datasheet wording be flagged for clarification?

    Do you mean the statement "must be provided first" ?
