Note

1:

Not 100% tested.

3:

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

200 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.
