_______________________________________________________________________________________
Note 1: All parameters tested at TA = +25°C. Specifications over temperature are guaranteed by design and characterization.
Note 2: When X1 is used as an external reference.
Note 3: Guaranteed by design and characterization; limits are set at ±6 sigma.
Note 4: Includes crystal accuracy.
Note 5: FXTL = 27MHz. Nominal frequency.
Note 6: See frequency selection paragraph in the Applications Information section.
Note 7: A master device must provide a hold time of at least 300ns for the SDA signal (referred to VIL of the SCL signal) in order to
bridge the undefined region of SCL’s falling edge.
Note 8: Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 VDD and 0.7 VDD.
Note 9: Bus sink current is less than 6mA. Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 VDD and
0.7 VDD.
Note 10: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
I2C TIMING CHARACTERISTICS
(VDD = VDD_P = 3.0V to 3.6V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C, VDD = VDD_P = 3.3V;
