Conditions

2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region

(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.

4: This parameter is not tested but ensured by characterization. For endurance estimates in a specific

application, please consult the Total Endurance™ Model, which can be obtained from Microchip’s web site

at www.microchip.com.
