7.6 I2C Interface Timing

minimum and maximum specifications are over –40 °C to 125 °C and VDD = 1.62 V to 5.5 V (unless otherwise noted)(1)
STANDARD MODE FAST MODE FAST MODE PLUS UNIT
MIN MAX MIN MAX MIN MAX
f(SCL) SCL operating frequency(2) 1 100 1 400 1 1000 kHz
t(BUF) Bus-free time between STOP and START conditions 4.7 – 1.3 – 0.5 – µs
t(SUSTA) Repeated START condition setup time 4.7 – 0.6 – 0.26 – µs
t(HDSTA) Hold time after repeated START condition.
After this period, the first clock is generated.		 4.0 – 0.6 – 0.26 – µs

(1) The controller and target have the same I/O supply value. Values are based on statistical analysis of samples tested during initial release.
(2) The TMP4718 is equipped with a 50-ns spike filter on both SCL and SDA lines. The filter allows the device to be used alongside I3C devices without impacting the communcation.
(3) The maximum t(HDDAT) can be 3.45 µs and 0.9 µs for Standard Mode and Fast Mode, but must be less than the maximum of t(VDAT) by a transition time.
(4) t(VDAT) = time for data signal from SCL LOW to SDA output (HIGH to LOW, depending on which is worse).
