8 / 30 page 8 of 30 July 17, 2012 Pin Assignment Pin Description Pin Functional Descriptions Serial Clock (SCL) This input signal is used to strobe all data in and out of the device. In applications where this signal is used by slave devices to synchronize the bus to a slower clock, the bus master must have an open drain output, and a pull-up resistor can be connected from Serial Clock (SCL) to VDDSPD. (refer to the Maximum RL Value vs. Bus Capacitance figure on how the value of the pull-up resistor can be calculated). In most applications, though, this method of synchronization is not employed, and so the pull-up resistor is not necessary, provided that the bus master has a push-pull (rather than open drain) output. Serial Data (SDA) This bi-directional signal is used to transfer data in or out of the device. It is an open drain output that may be wire-ORed with other open drain or open collector signals on the bus. A pull up resistor must be connected from Serial Data (SDA) to the most positive VDDSPD in the I2C chain. (refer to the Maximum RL Value vs. Bus Capacitance figure on how the value of the pull-up resistor can be calculated).
