S32K functional safety

xinshen — Mon, 30 Nov 2020 06:17:40 GMT

We have some problem on understanding the functional safety of NXP S32K144, as below: 1. In S32K144 FMEDA Core part, there are modules like: Miscellaneous Control Module (MCM), System Mode Controller (SMC), Reset Control Module(RCM), and Test Logic. What’s the function of these modules. And MCM, SCM, and RCM are single point failures, but without safety mechanisms. What are the corresponding failure modes and how to handle/consider them? 2. In S32K144 FMEDA Clock part, there is module SCG, what’s the difference with XOSC and PLL? What’s the function of PCC, SIM and CCM modules? And these modules are single point failures, but without safety mechanisms. What are the corresponding failure modes and how to handle/consider them?

Hello Xin Shen,

All the modules are described in the S32K1xx Reference Manual.

Regarding FMEDA, please post it in the SafeAssure NDA community group:
