FS26 Replacement Part Number for MR-CANHUBK344

patricklanglois — Wed, 06 Sep 2023 20:25:53 GMT

Hi,

We have the MR-CANHUBK344 evaluation board on which we want to base a new design. Looking at the schematics, I see a preliminary part number for the FS26 SBC. What would be the final part number these days to replace this one if I have to or if I want to use the same component.

Regards,

I don't see the MR-CANHUBK344 evaluation board in this list. Is there a mistake? This list looks like an excerpt of a more complete document. Would you please provide the reference to the document where I can find the complete list if this one includes the evaluation board I mentioned here?

This EVB used this MCU:

My question is about the SBC not the mcu.

The kind of answer I'm looking for is similar to the one of the post "FS26 chip of S32K312EVB-Q172", but transposed to the eval board MR-CANHUBK344.

For the S32K344,you can select FS26 from below list:

With no intent of disrespect, as you repeat your answer, I suppose that I must repeat my question following it...

I don't see the MR-CANHUBK344 evaluation board in your list. Is there a mistake here?

But at the end, what I want to know from my initial statement is simply:

What is the production part number for the FS26 SBC to specifically replace the one on the MR-CANHUBK344 evaluation board? Your list specifies other evaluation boards, not this one that we purchased. And, the schematics of this board are still pointing a preliminary part, while a production part probably exists now. Are all the components in your list a fit to replace the one on my evaluation board and to supply the S32K3? I want to identify the right variation of the FS26 SBC to properly analyze the evaluation board design.

P.S.: Initially, I was expecting an answer like @VanB was able to provide to the post "FS26 chip of S32K312EVB-Q172". Please let me know if I demand the impossible.

There is nothing in this thread that I could consider an acceptable solution. Based on my past experiences and reading other discussions, I think it's a matter of luck if we can get a proper answer from the NXP Tech Support. Feel free to close this thread if you can't be more explicit. BTW, I can consider as acceptable a simple answer like "we have no way to identify a single production part number to the preliminary one that is suitable to replace the FS26 chip on the MR-CANHUBK344 evaluation board." But, this might bring some questions about NXP's control over what they make.

I compared your EVB FS26 regulator output sequence and Vout, there is no suitable FS26 OTP part for recommend, they are not match/different.

So you can try to buy A0 blank part and do OTP by yourself with the OTP socket board.
