(13) I2C Timing
(TA
= −40 °C to +125 °C, VCC = AVCC = 5.0 V ± 10%, fCP ≤ 24 MHz, VSS = AVSS = 0 V)
*1 : R,C : Pull-up resistor and load capacitor of the SCL and SDA lines.
*2 : The maximum tHDDAT has to meet at least that the device does not exceed 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
tSUDAT
≥ 250 ns must be met.
*4 : For use at over 100 kHz, set the machine clock to at least 6 MHz.
*5 : Refer to “
• Note of SDA, SCL set-up time”.
