K10 Vref Factory Trim

Question asked by phil74 Employee on Dec 7, 2016

Hello

 

We’re encountering an issue with VREF on MK10DX128VLH5:

VREF_OUT value (in steady state) is 1.182V whereas on other PCB we have 1.196V.

 

Conditions:

VREF_TRM[CHOPEN], VREF_SC[]REGEN] and VREF_SC[ICOMPEN] bits are set.

VREF_TRIM[TRIM] is untouched.

 

So we except to reach datasheet figures (between 1.1915 and 1.1977V).

 

Datasheet specifies two ranges with factory trim:  from 1.915 to 1.1977V or from 1.584 to 1.2376V

 Can you give us more details about these two ranges ? What should be the expected range ?

 

 

 

Thanks in advance,

Best regards,

Philippe
