I
The characterization timing is done considering an output load of 10 pF on SCL and SDA.
The operating conditions are V = 0.90 V, T
in best case.
Figure 17. I
Figure 18. I
The flip-flops used to capture the incoming signals are re-synchronized with the AHB clock
(HCLK): so, no input delay calculation is required.
