MTTF/MTBF of nRF52840, nRF52833 and nRF52832?

[Job Groenendaal]

Hi,

I am writing to inquire about the MTTF, MTTFd, MTBF and/or FIT value of the nRF52840. nRF52833 and nRF52832. Where can I find these values?

This question has been previously asked for the nRF52832 (https://devzone.nordicsemi.com/f/nordic-q-a/31985/what-is-the-lifetime-expectancy-of-nrf52832-ic), but the value might be outdated since the request is over 3 years old.

Thanks in advance.

Thanks for your fast reply.
Does this processor have a safety manual, where the FIT rate and other safety relevant topics are provided?
