Figure 30. I2C bus AC waveforms and measurement circuit

1. RS = series protection resistor.

2. RP = external pull-up resistor.

3. VDD_I2C is the I2C bus power supply.

4. The maximum data hold time has only to be met if the interface does not stretch the low period of SCL

signal.

5. The minimum width of the spikes filtered by the analog filter is above tSP (max)

Table 61. SCL frequency (fPCLK1= 50 MHz, VDD = VDD_I2C = 3.3 V)(1)(2)

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

2. For speeds around 200 kHz, the tolerance on the achieved speed is of

±5%. For other speed ranges, the

tolerance on the achieved speed is

±2%. These variations depend on the accuracy of the external

components used to design the application.
