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,

If your I2C peripheral demands tight voltage regulation during fast clock transitions, the MIC5512-3.3YMT-TR LDO is ideal. It offers excellent transient response and low dropout, making it suitable for supporting I2C operations in noise-sensitive embedded systems where stable 3.3V is crucial for reliable communication.
