Electrical characteristics

STM32F302xB STM32F302xC

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 RM0365 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).
