Can L9788 be interfaced to a microcontroller via SPI?

[AlxCrt]

Hello all, 

this post just to know if the L9788 Automotive Engine Management System IC can be interfaced to a microcontroller via SPI instead of MSC bus (single ended interface instead of differential one).

Thanks a lot,

Regards.

AC.

Surely, the datasheet would tell you that?

Welcome @AlxCrt, to the community!

The MSC is an asymmetric bus, see also here.

Perhaps MSC could be replicated with two SPI and some gluelogic, but I am not aware of any such implementation. But why emulate it when there are MCUs that have this interface natively?

Thank you so much Peter for your answer,

"But why emulate it when there are MCUs that have this interface natively?" 

because I must use a microcontroller that doesn't have MSC bus properly "natively" it has the MSC support by one specific mode of the DSPI unit, so since the driver for the SPI is just ready and the MSC driver should be written, I made the question just to save time in case.

I know there are other chips that permit to interface with SPI or MSC that is why I asked you.

PS. I know Infineon implement MSC bus natively on some microcontroller, which ST's Automotive microcontroller implement it natively?

Regards,

AC.

Hello,

Please refer to this Eval board: EVAL-L9788 its using SPC563M64L automotive MCU.

I don't have idea about the MSC interface but according to the schematics of the previously mentioned Eval board:

It shows the following (last page):

May be you need to look at this direction.
