1. RP = External pull-up resistance, fSCL = I2C speed,

2. For speeds around 400 kHz, the tolerance on the achieved speed is of ±2%. For other speed ranges, the

tolerance on the achieved speed ±1%. These variations depend on the accuracy of the external

components used to design the application.

3. Guaranteed by design, not tested in production.
