Note 1:
Not 100% tested. C
B
= total capacitance of one bus line in pF.
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.
3:
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:
www.microchip.com.
