*1: R and CL represent the pull-up resistance and load capacitance of the SCL and SDA output lines, respectively. VP
shows that the power supply voltage of the pull-up resistor and IOL shows the VOL guarantee current.
*2: The maximum tHDDAT only has to be met if the device does not extend the "L" width (tLOW) of the SCL signal.
*3: A high-speed mode I
2C bus device can be used on a standard mode I2C bus system as long as the device satisfies
the requirement of "tSUDAT
≥ 250 ns".
*4: tCPP is the peripheral clock cycle time. Adjust the clock of the peripheral bus to 8MHz or more when using I
2C.
*5: Only available with MB91F583AM/F584AM/F585AM
