Do GreenPAK devices use I2C clock stretching?

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?
