CB ≤ 100 pF
Note 1: Not 100% tested. CB = 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: The combined TSP and VHYS specifications are due to new Schmitt Trigger inputs which provide improved noise spike
suppression. This eliminates the need for a TI specification for standard operation.
4: This parameter is not tested but established 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.
5: Max. clock frequency is 100 kHz for E-temp devices <4.5V. 1.7-2.5V (100 kHz) timings must be used.
6: Max. clock frequency is 400 kHz for 24FC1025, VCC < 2.5V.
