Figure 25. I2C bus AC waveforms and measurement circuit

1. Rs: Series protection resistors, Rp: Pull-up resistors, VDD_I2C: I2C bus supply.

1. The I2C characteristics are the requirements from I2C bus specification rev03. They are guaranteed by design when

I2Cx_TIMING register is correctly programmed (Refer to the RM0316 reference manual).

2. The maximum tHD;DAT could be 3.45 µs, 0.9 µs and 0.45 µs for standard mode, fast mode and fast mode plus, but must

be less than the maximum of tVD;DAT or tVD;ACK by a transition time.

3. The minimum width of the spikes filtered by the analog filter is above tSP(max).
