Typ. Max. SCL clock frequency fSCL 0 400 kHz SCL hold time (start/restart condition) tHD:STA 0.6 µs SCL ”L” level time tLOW 1.3 µs SCL ”H” level time tHIGH 0.6 µs SCL setup time (restart condition) tSU:STA 0.6 µs SDA hold time tHD:DAT 0 µs SDA setup time tSU:DAT 0.1 µs SDA setup time (stop condition) tSU:STO 0.6 µs Bus-free time tBUF 1.3 µs Note: Current drive ability of PA3, PA5, PB0 and PB6 in N-ch open drain mode is lower than that of PA0 and PB7. Therefore, the fast mode (400kbps) cannot be available when PA5 or PB0 is set as SCL function and when PA3 or PB6 is set as SDA function. For more details, see the characteristics of VOL1 and VOL2 in DC Characteristics (VOHL, IOHL).
