Note:

AC measurement conditions:

– CL: 100 pF

– RPUP (SDA bus line pull-up resistor to VCC): 1.3 kΩ (1000 kHz), 4 kΩ (400 kHz), 10 kΩ (100 kHz)

– Input rise and fall times: ≤ 50 ns

– Input and output timing reference voltages: 0.5 x VCC

This parameter is characterized but is not 100% tested in production.
