(8) I2C Timing
(VCC = 5.0 V
± 10%, AVSS = VSS = 0.0 V, TA = 40° C to + 85° C)
*1: R represents the pull-up resistor of the SCL and SDA lines, and C the load capacitor of the SCL and SDA lines.
*2: The maximum tHD;DAT in the Standard-mode is applicable only when the time during which the device is holding
the SCL signal at “L” (tLOW) does not extend.
*3: A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system, provided that the condition
of tSU;DAT
≥ 250 ns is fulfilled.
