S32K342 EMMC memory 64GB

[thomasfelixberg]

Hi Guys

For a new project i search a solution to connect a 64GB EMMC memory IC to a S32K342 processor to safe CAN Data on it.

Due to the rough environment i cant use an SD Card.

Do you know if this is possible?

How do i have to connect it?

Is there an EVAL board that can be used to try this out?

Thanks that helped me.

Do one of you have experience with EMMC and the S32k?

Which maximal size of the EMMC is possible?

Which standard is possible? 4.1 od 5.0?

Regarding size, there is probably no hard limit and it is given only by addressing of eMMC. Supported version you see below:

Unfortunately we don't have experience.

Thank you for your feedback.

Do you have any idea how we can test it? 

Is there a demoboard where we can adopt to the EMMC interface an make a demo setup?

On the other hand - do you have a other solution for our problem?

We want to log 4 CANFDs and safe it for a long period of time (5-10 years)

the uC has to start and log very fast

We have one board with SDHC connector mounted:

eMMC seems to be used with S32G device, seems there is directly installed memory, not a slot:

S32G is supported by different support group, in case there are questions to this, please create new thread/case. Thanks for understanding

Thats what i needed.

best regards

RTD_MEM_43_EEP driver supports eMMC cards, but S32K342 does not have uSDHC controller that is necessary.

It is needed to have one of MCU below:
