6.13.4 I2C electrical characteristics
VDDQ = 2.7 - 3.6V, VDD = 1.65 - 2V, TA = -40 / 85 °C unless otherwise specified.
Table 24.
I2C Electrical Characteristics
Notes: 1 The device must internally provide a hold time of at least 300 ns for the SDA signal in order to
bridge the undefined region of the falling edge of SCL
2 The maximum hold time of the START condition has only to be met if the interface does not
stretch the low period of SCL signal
3Cb = total capacitance of one bus line in pF
