URGENT - Liv4F operating voltage range

[EGola.1]

Liv4F module. 

 

Operating voltage range in the data sheet stated 3v-3.3v

In the Manual 1.8v-3.3v  what is true? 

 

Can you fix the documents???

Hi @EGola.1 ,

 

Thank you for the valuable remark :

on our TESEO LIV4F module . 

have a great Sunday

So, 1-8v-3.3v? 

 

Correct?

Hi,

LIV4F can operate only at 3.3V. 

We are fixing the documentation and releasing it this quarter.

Thanks for your patience.

so now we have also conflicting statements from ST employees here: STOne-32 points to UM3004 (stating 1.8V to 3.3V, can be left floating) and GalaxyQuest writes "only 3.3V" which is not even the spec from the data sheet (3V too 3.63V).

Is there any chance of a final statement? And fixed documentation?

[GalaxyQuest]

Hi,

For operating conditions like voltage, the datasheet takes precedence, therefore 3V - 3.63V. LIV4F cannot operate down to 1.8V. The hardware manual, UM3004 is mainly for pin guidelines.

Hope this helps.

Thank you @GalaxyQuest  confirming the statement . Much appreciated 

Dear @bofh ,

Hope now it is more clear .

have a great day
