At slave mode operating
(VDDE
= 3.3 V ± 0.3 V, VDDI = 1.8 V ± 0.15 V, VSS = 0 V, Ta = 10 °C to + 70 °C)
*1 : M = Resource clock cycle (ns)
*2 : A high-speed mode I2C bus device can be used for a typical mode I2C bus system as long as the device satisfies
a requirement of “tSUDAT
≥ 250 ns”.
When a certain 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) in which the SCL line is released.
*3 : For use at over 100 kHz, set the resource clock to 6 MHz or higher.
*4 : R and C represent the pull-up resistor and load capacitor of the SCL and SDA output lines, respectively.
