Our PA team is doing the timing verification and found that the Tf/Tr of the I2C signal can not meet the timing requirement. We see theLP5521 define the I2C fast mode (clk < 400kHz) in the datasheet but we use standard mode (clk < 100kHz) to operate it. The fail item is the Tf/Tr because the fast mode defines a min. value but the standard only defines the maximum value.
Does the LP5521 support the standard mode timing for us to ignore the Tf/Tr issue?
