However, I am concerned about the value of the answer.
Previously, we confirmed FIT and MTTF of other products (WiFi / BT combo chip), but FIT and MTTF of this response were the same as those of other products (WiFi / BT combo chip).
Is this answer correct with FIT and MTTF of CYBT-343026-01?
I think this answer is correct. My understanding is the module has the same FIT/MTTF with the chip on it, and the reason you see the values are same both for BT and WiFi/BT combo chips is they use same technology process. I would recommend you to contact your local Cypress office support team if you have doubt with this information.
