STPM33/34 MISO & Insulating barrier

[Martin68]

Hello everyone

I am looking into the STPM33/34. I only want to use 1 SPI bus for both ICs and select it with the SCS.

In the datasheet I cannot see whether the MISO goes into tristate when the IC in question is not active.

I also cannot see any information about the galvanic isolation/barrier.

Can anyone give me information about this.
Thank you in advance.

Hello,

The MISO line is in Hi-Z mode when the STPM3x is not selected (SCS at high level).

Just note this limitation in case you use several STPM3x in parallel:
