Hi Teams        Customer(BYD) have questions that what is specific safety goal for S32K3xx as SeooC. ,like MPC5746R as below: Best Regards Junjie ... View more

I have reviewed the FMEDA excel data for the S32K312 MCU, and there are a few things to check, so I would like to request it. 1) The data I have is only applied in accordance with IEC-TR-62380 regarding Permanent Failure Rate. I would like to request that NXP provide me with the Failure Rate calculated using SN29500. 2) Among the failure rates predicted by IEC-TR-62380, the percentage of permanent die and package seems strange, so I would like to know the calculation conditions for permanent failure. (i.e. No of TR. 7.894E7, MOS, BiCMOS (low voltage) digital circuits, power 0.6W & Thermal resistance 35.3degC/W, package pin pitch 0.325, package width 10) Of the Permanent Total 130.4158 FIT, 0.4158 FIT was assigned to Die in FMEDA excel, and 130 FIT was assigned to Package. There is a difference from the actual calculation result according to IEC-TR-62380, so it is necessary to check whether the die calculation was calculated as Ton + Toff = 1 rather than Ton = 1. ...

Hello NXP Team, SM_133 and SM_137 require redundancy at HW. In our system(ASILB), ADC and GPIO inputs are safety relevant. Both ADC and GPIO inputs are used to monitor the power supply. ADC check the voltages on power rails are within expected range and GPIO indicates error status of PMIC. Do the assumptions on redundancy apply for ASILB?  Will these be necessary if below SW mechanisms are implemented ADC - ADC tests suggested in manual. GPIO - Stuck to Battery/GND checks at startup. ... View more

Hi NXP team, The below assumption on NXPS32K14x is mentioned under HW requirements and requires system to monitor the error flags. Assumption: [SM_043] The overall system needs to include measures to monitor error flags in registers of the MCU and move the system to a Safe statesystem when an error is indicated. [end] Question - How is it possible to check the error flags in the registers of MCU from an external source? Is it sufficient that register monitoring is implemented in SW within the MCU and we enter safe state from SW?  If not, can you provide some implementation hints?   ... View more
