(13) I2C Timing
(VCC
= 2.7 V to 3.6 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
*1 : fcp is internal operation clock frequency. Refer to “ (1) Clock Timing Standards”.
*2 : R,C : Pull-up resistor and load capacitor of the SCL and SDA lines.
*3 : The maximum tHDDAT only has to be met if the device does not stretch the “L” width (tLOW) of the SCL signal.
Note : VCC
= VCC3 = VCC5
