7.6 Two-Wire Timing Requirements

at TA = –40°C to +125°C and V+ = 1.7 V to 3.6 V (unless otherwise noted)
The master and the slave have the same V+ value. Values are based on statistical analysis of samples tested during initial release.
MIN MAX UNIT
fSCL SCL operating frequency Fast mode 0.001 0.4 MHz
High-speed mode 0.001 2.56
tBUF Bus free time between stop and start condition Fast mode 1300 ns
High-speed mode 160
tHD;STA Hold time after repeated start condition.
After this period, the first clock is generated.		 Fast mode 600 ns

(1) The maximum tHD;DAT can 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).
