Hi Nxp,
I have been using FS2613 SBC chip and I found safety requirement (SM48) which is related to Fail safe oscillator drift Fault (FS_OSC_DRIFT). But ASIL level information is not available in reference manual.
So, kindly clarify that, this fault comes under either ASIL B/ ASIL D/ QM?
Thanks,
Sivahari G
Hello Sivahari
Good day!
The FS_OSC_DRIFT fault (SM48) corresponds to the monitoring of the independent fail-safe oscillator used by the FS26 fail-safe state machine. According to the FS26 Safety Manual, this mechanism is implemented within the ASIL D fail-safe domain.
You can find this representation in Figure 8. Safety architecture.
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
