(8) I2C Timing
(VCC
= 3.3 V, AVSS = VSS = 0.0 V, TA = 40 °C to + 85 °C)
*1 : R, C : Pull-up resistor and load capacitor of the SCL and SDA lines.
*2 : The maximum tHD;DAT have only to be met if the device dose not stretch 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.
