When operating in slave mode
(VDDE
= 3.3 V ± 0.3 V, VDDI = 1.8 V ± 0.15 V, VSS = 0 V, Ta = 40 °C to + 85 °C)
*1 : For use at over 100 kHz, set the resource clock to 6 MHz or higher.
*2 : R and C represent the pull-up resistance and load capacitance of the SCL and SDA output lines, respectively.
*3 : M = Resource clock cycle (ns)
*4 : A high-speed mode I2C bus device can be used on a standard mode I2C bus system as long as the device
satisfies the requirement of “tSUDAT
≥ 250 ns”.
When a device does not extend the “L” period of the SCL signal, the next data must be output to the SDA line
within 1250 ns (maximum SDA/SCL rise time
+ tSUDAT) from when the SCL line is released.
