RPU (Note 8) SDA and SCL Bus Pull-up Resistor Off-chip Maximum is determined by tR and tF.
For Cb = 400pF, max is about 2kΩ ~ 2.5kΩ.

For Cb = 40pF, max is about 15kΩ ~ 20kΩ
NOTES:
8. Limits should be considered typical and are not production tested.
9. These are I2C specific parameters and are not tested, however, they are used to set conditions for testing devices to validate specification.
10. Cb is the capacitance of the bus in pF.
