6.15.4 I2C electrical characteristics

VDDQ = 2.7 - 3.6V, VDD = 1.65 - 2V, TA = -40 / 85 °C unless otherwise specified.

Table 32.

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
