Hi Michael,
I really apologize that you did not receive back information related to your question.
We do have FIT rate data that we can provide upon request, please do contact me by email (justin.mortimer@nxp.com).
Also, we do have as part of our strategic plan to address Industrial Functional Safety (IEC61508) for these new MCUs, there is more to come in this area within 2021, but as of today, we do have IEC60730 class B enablement for LPC5500 MCU series, among others.
Regards,
Justin
