is the cycle time for the internal operation clock. Refer to (1) “Clock timing ratings”.
*2 : The high-speed mode I
2
C bus device can be used in a standard mode I
2
C bus system. However, the device
must satisfy the required condition “t
SUDAT
250 ns”. If the device does not extend the “L” period of the SCL
signal, the succeeding data must be output to the SDA line before a period of 1250 ns (the maximum time of
SDA/SCL rise
+
t
SUDAT
) in which the SCL line is open.
*3 : Set the internal operation clock to 6MHz or higher when using this over 100kHz.
*4 : “R” and “C” are the pull-up resistance and load capacitance of the SCL/SDA lines.
