Note 1: The pull high/low impedance was defined under C
b
(total capacitance load for each SDA/SCL lines)400pF
for standard mode and 300pF for fast mode. If C
b
smaller than 400pF/300pF, I2C circuit can chose higher
impedance for saving sink power. The minimum impedance was defined under I
d
(sink current) of 3mA. All
the above condition was defined with internal pull high impendence of 4.7k to 5.3k.
Note 2: The power consumption depends on sensor loading condition.
