Hi team,

My customer asks about how long SDI hold time is required.

It's not defined in Electrical Spec table, can you support this question?

best regards,

Hi FUJIHARA-san,

Data is captured on the falling edge of SCLK and expectation is that data does not change during SCLK low period. So, we can say that SDI hold time is same as SCLK low min duration, which is 45ns. Are they facing any issues with it or they are just asking as they didnt find this information in the datasheet?

Regards,

Murthy

Hi Murthy-san,

Thanks for prompt support.

Customer don't have issue in SPI access, it's because they are just required to clarify it during customer internal design review.
