About Input the Osc clock (32.768kHz) during i.MX6 power off.

Dear All,

 

Hello. My customer has used i.MX 6Dual and PF0100.

PF0100's VSNVS output starts from 1.0 V when LICELL is valid before VIN.

*Refer to "Figure 6. Default start-up sequence" in MMPF0100Z(Rev.10).

 

And, the VSNVS output to external oscillator (32.768kHz), too.

But, the oscillator started the operation at 1V.

The Osc clock has been inputted to i.MX6 with power off.

(VDD_SNVS_CAP was 0V. So internal LDO looks disabled.)

*Refer to attached system structure.

 

[Question]

Does the Osc clock give i.MX damage during above situation?

(Or, is there possibility to destroy the i.MX6 device?)

Amplitude of osc clock was measured 1.1V.

 

Best Regards,  

Keita
