At present, when designing THE VDD nuclear voltage of LX2160A, the description of development board SCH-29455 is inconsistent with 0.85 of specification LX2160ARM. The former can choose 1.05V, while the latter has a maximum of 0.88V. What is the reason?In addition, how does VID control VDD voltage? Under what circumstances does it change voltage?thank you.

> The former can choose 1.05V

In which document this is stated?

Hi, ufedor

Lx2160_rdb_revb5-sch has this annotation:

VDD: 0.8V (LX2160A)
         1.0V (LS2081A)
         +/-3%
       @70A

   Please check.  Thank you!

> 1.0V (LS2081A)

This means 1.0V for the processor interposer based on the LS2081A.
