SCL

This input clock pin is used to synchronize the data

transfer to and from the device.

SDA

The SDA is a Bi-directional pin used to transfer addresses

and data into and out of the device. The SDA pin is an open

drain output and can be wire-Ored with other open drain

or open collector outputs. The SDA bus requires a pullup

resistor to Vcc.

A0, A1, A2

The A0, A1 and A2 are the device address inputs that are

hardwired or left not connected for hardware compatibility

with the 24C16. When pins are hardwired, as many as eight

32K/64K devices may be addressed on a single bus

system. When the pins are not hardwired, the default values

of A0, A1, and A2 are zero.

WP

WP is the Write Protect pin. The input level determines if all,

partial, or none of the array is protected from modifications.
