Hello,
GreenPAK devices such as SLG47004V and SLG46826G use I2C slaves for programming and for normal operation.
Do these I2C slaves use I2C clock stretching? I couldn't find any reference in the datasheet.

Thanks
For some GreenPAK devices (including the SLG47004 and the SLG46826), the SCL pin is documented to be an input (not input/output). Therefore, there can be no clock stretching on those devices.
For other GreenPAK devices (such as the SLG46538), the SCL pin is documented to be input/open drain output. For those devices, clock stretching cannot be ruled out from reading the datasheet.
Thanks @klamm, the output only is a good observation.
Renesas, can you please confirm that the rest of the GreenPAK family also doesn't use I2C clock stretching?
Hi,
I will get back to you for other Greenpack.
Unfortunately, GreenPAK doesn’t have such feature of IIC Clock Stretching

Thanks AB. That's actually good for my use case.
