Input
Input pins for device address selection. To configure a device address,
these pins should be connected to the VCC or VSS of the device.

SDA
I/O
Bi-directional data pin for the I2C-bus serial data interface. Schmitt
trigger input and open-drain output. An external pull-up resistor must
be connected to VCC. Typical values for this pull-up resistor are 4.7 kW
(100 kHz) and 1 kW (400 kHz).

Input
Schmitt trigger input pin for serial clock input.
Input pin for hardware write protection control. If you tie this pin to VCC,

the write function is disabled to protect previously written data in the
entire memory; if you tie it to VSS, the write function is enabled.
