*1: The I2C Bus Fast Mode I/O buffer is downward compatible with standard mode.
*2: 90nm Technology: Complies with the maximum ratings 4[V].
*3: Cb: Capacitance for 1 bus line (Unit: pF).
*4: The I2C Bus Fast Mode I/O buffer itself has no function to prevent spike of 50ns pulse width (max.). Therefore,
provide any input filter to prevent spike for both internal and external semiconductor device.
Note:
External pin for I2C IO buffer is as follows.
I2C_SCL0, I2C_SDA0, I2C_SCL1, I2C_SDA1
