Can you say what could be the failure mode in case we store below -50C?

Per this report the ALT Temperature cycling test for lots ahs been done at -65 Deg C so -55 Deg C can be no issues for storage, please comment

I noticed that in both these SoC chips the ALT temperature cycling had been done for -65 to 105^o C (per Item #3), per the PQR report shared. Can this be validated for storage as well?

We don't have any test data outside of what the SoCs are specified for, as we test them particularly for these temperatures to comply with industry standards. So storing or using the nRF5340 or nRF7002 at temperatures below -40C is not tested by us and outside of specification. This means that we don't know how it will behave if exposed to temperatures outside of this, and reduced reliability and failures must be expected.

Best regards,
