(13) I2C Timing
(TA
= –40°C to +105°C, VCC = 5.0 V ± 10%, VSS = 0.0 V)
*1: For use at over 100 kHz, set the machine clock to at least 6 MHz.
*2: R,C: Pull-up resistor and load capacitor of the SCL and SDA lines.
*3: The maximum tHDDAT meets the requirement that it does not extend the “L” width (tLOW) of the SCL signal.
*4: A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system, but the requirement
tSUDAT
≥ 250 ns must then be met.
