How to select the proper MCUs for ISO26262 safety applications

[lu00188876926E12]

Dear all,

I am working on a prototype with anti-tilting and park-brake functions that need to be complied with ISO26262. So far the ASIL is not determined yet, I want to start development and testing the firmware in a complete toolkit.

However I am not sure which MCU to choose.

For example, the SPC56 L line and SPC58 C line both provide ASIL and safety applications, and evaluation toolkit, though mentioned that SPC58 C key functions are securing on-board communication protocol.

I have the same difficulty in selecting from other A/B/2B/G/P/etc.

And how about the generic control STM32 MCU's, if I only want the mentioned two functions, it seems the STM32 MCU is qualified as well, is it correct?

Thanks in advance for explaining with details.

Hello ,

About ASIL-D certifications ,

SPC56 L line and SPC58 C line provides ASIL-D certification.

STM8A

on STM32 , I do not know ,

i advice to ask directly in the forum STM32

Best regards

Dear Erwan,

Thanks a lot for replying.

I am new to MCU units and would like to learn how to implement ISO 26262 ASIL A/B functions in the future.

So as a start, I want to build a prototype that demonstrate EPB safety function, say the scope covers from 1 AI & 1DI to 2 DO's.

What would be your recommendation to buy as a cheap but minimal learning packages?

SPC MCU + SPC5Studio or commercial S/W packages like autosar MCAL will be needed?
