I/O logic support at 1.2V for QSPI

[saminathan]

Hi,

we are planning to use STM32H742xI/G controller in our design, we have reviewed the datasheet and need a clarification on the IO logic for QSPI.

Does this controller supports 1.2v IO logic for the QSPI.

Hello @saminathan and welcome to the community;

 

Unfortunately, 1V2 IO logic for QUADSPI interface isn't supported. Please look at this post.

This request is already shared with expert.

 

Thank you.

Hi @KDJEM.1,

Ok as suggestion, we are going to plan to use bi-directional level translator SN74AXC4T245PWR.

Does it work if we use level translator?

Thanks,

Hello @saminathan ;

 

To verify whether it is functional or not, you need to check that the signals required for SN74AXC4T245PWR must be compatible with the QUADSPI signals.

 

Thank you.
