Remarks

1: R and CL represent the pull-up resistance and load capacitance of the SCL and SDA lines, respectively. Vp indicates
the power supply voltage of the pull-up resistance and IOL indicates VOL guaranteed current.
2: The maximum tHDDAT must not extend beyond the low period (tLOW) of the device’s SCL signal.
3: The Fast mode I²C bus device can be used on a Standard-mode I²C bus system as long as the device satisfies the
requirement of tSUDAT ≥ 250 ns.
4: tCYCP is the APB bus clock cycle time. For more information about the APB bus number to which the I²C is connected, see
8.Block Diagram in this data sheet.
To use fast mode plus (Fm+), set the peripheral bus clock at 64 MHz or more.
5: The noise filter time can be changed by register settings. Change the number of the noise filter steps according to the APB
bus clock frequency.
6: When using fast mode plus (Fm+), set the I/O pin to the mode corresponding to I²C Fm+ in the EPFR register.
See Chapter 12: I/O Port in FM4 Family Peripheral Manual Main Part (MN709-00001) for the details.
