(8) I
*1 : R, C : Pull-up resistor and load capacitor of the SCL and SDA lines.
*2 : The maximum t
*3 : A fast-mode I
*4 : Refer to “ • Note of SDA and SCL set-up time”.
Note : The rating of the input data set-up time in the device connected to the bus cannot be satisfied depending on
SCL clock frequency
SDA ↓ → SCL ↓
SCL clock “L” width
SCL clock “H” width
SCL ↑ → SDA ↓
Data hold time SCL ↓ → SDA ↓ ↑
Data setup time SDA ↓ ↑ → SCL ↑
Stop condition setup time

Be sure to adjust the pull-up resistor of SDA and SCL if the rating of the input data set-up time cannot be
satisfied.
• Note of SDA and SCL set-up time
