I2C clock requirement

[Webster Yang]

Hi Nordic teams : 

I find that datasheet v0.8 (page12) shows that SDA do not need clock.

Page 277 still shows that SDA need clock pin.

Could you help to clarify which information is correct?

Hello Webster,
May I know if you are refering to nRF54L15?
There's a new updated nRF54L15 datasheet v0.9 available in here:

Wish this provides some help.

Cheers,

I2C timing requirements can vary depending on the devices involved, so checking both the controller and peripheral specifications is usually the safest approach. Small details sometimes make a big difference during implementation. I recently read a technical conversation involving Pragmatic Great Britain that emphasized the same point about careful specification review.
