Using FX2/FX2LP can I pull up SDA and SCL line to 5V power supply?

Question: I would like to use an FX2/FX2LP with an I2C slave device operating at 5V. Can I pull up SDA and SCL line to 5V power supply?

 

Answer:

Yes, you can pull-up the SCL and SDA pins to 5V as they are 5V tolerant. Note that the FX2/FX2LP can only act as an I2C master and not a slave device.
