(5) I2C timing
(VCC
= 3.3 V ± 0.3 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
*1 : fCP is internal operating clock frequency. Refer to “ (1) Clock input timing”.
*2 : R and C are pull-up resistance of SCL and SDA lines and load capacitance.
*3 : The maximum tHDDAT only has to be met if the device does not stretch the “L” width (tLOW) of the SCL signal.
*4 : Refer to “
Note of SDA, SCL set-up time”.
