About the VSNVS output voltage of PMIC and VDD_SNVS_IN input voltage of i.MX6

Dear all,

We use i.MX6Solo and PF0100F0AEP.
I seem that a spec of the VSNVS output of PMIC do not match a spec of VDD_SNVS_IN.
I think that the Min value of VSNVS is less than the Min value of VDD_SNVS_IN.

Does this affect the operation of i.MX6solo?
Or, Is it the mistake of specifications of which?


For VDD_SNVS_IN of i.MX6Solo,
According to the "Table 8 Operating Ranges" in Datasheet, it is defined at 2.9V - 3.3V.

However, for VSNVS of PF0100,
According to the "Table 111. VSNVS electrical characteristics" in Datasheet, it is defined in 3.0V +/-5.0%.
So, the voltage range is from 2.85V to 3.15V.

May I have an advice?

Best Regards,
Yuuki

Hello,

 

  The selected in red variant of output PMIC SNVS voltage does not contradict

i.MX6 specs. Also, customers can use the case, based on external coin cell for

the PMIC: 2.84 V < VCOIN < 3.3 V.

 

Have a great day,

Yuri
