MC56F8037 I2C rise time

EngHuiPeng — Mon, 07 Nov 2016 14:08:38 GMT

Would like to check whether there is any tolerance/allowance on the I2C rise time of the DSC. Customer informed that their I2C rise time is approx ~1.744uS which exceeds the max 1uS rise time recommendation but the communication have no issue.

Thanks.

Regards,

Hui Peng

Hi, Hui,

The data sheet specifies that the maximum rising time for both SCL and SDA is 1uS in standard mode, but I think it is okay if the I2C module works fine even if the rising time is 1.7uS.

Hope it can help you
