(7) I2C Timing
(Vcc
= 3.3 V, Vss = 0.0 V, TA = 20 °C to +70 °C)
*1 : R, C : Pull-up resistance and load capacitance of the SCL and SDA lines.
*2 : The maximum value of tHD;DAT is applicable only if the device does not extend the “L” width (tLOW) of the SCL signal.
*3 : A fast-mode I2C-bus device can be used in a standard-mode I2C-bus system, but the requirement tSU;DAT
≥ 250
ns must then be met.
