6.7 Two-Wire Interface Timing

Over free-air temperature range and V+ = 1.7V to 5.5V for TA = –55°C to 70°C, or V+ = 1.8V to 5.5V for TA = –55°C to 150°C (unless otherwise noted)
STANDARD FAST-MODE UNIT
MIN MAX MIN MAX
fSCL SCL operating frequency 1 1 400 KHz
tBUF Bus free time between STOP and START conditions 1300 ns
tHD;STA Hold time after repeated START condition.
After this period, the first clock is generated(1)		 5 600 ns
tSU;STA Repeated START condition setup time 600 ns
tSU;STO STOP condition setup time 600 ns
tHD;DAT Data hold time 0 ns
tVD;DAT Data valid time(2) 0.9 µs
tSU;DAT Data setup time 100 ns
tLOW SCL clock low period 1300 ns
tHIGH SCL clock high period 600 ns
tF – SDA Data fall time 20 × (V+ /5.5) 300 ns
tF, tR – SCL Clock fall and rise time 300 ns
tR Rise time for SCL ≤100 kHz 1000 ns
Serial bus timeout (SDA bus released if there is no clock) 20 40 ms
(1) The maximum tHD;DAT could be 0.9 µs for Fast-Mode, and is less than the maximum tVD;DAT by a transition time.
(2) tVD;DAT = time for data signal from SCL "LOW" to SDA output ("HIGH" to "LOW", depending on which is worse).
