Serial Data (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open drain driven and may be wire-ORed with any number of other open-drain or open-collector devices. Device Addresses (E2, E1, E0): The E2, E1 and E0 pins are device address inputs. Typically, the E2, E1 and E0 pins are for hardware addressing and a total of 8 devices can be connected on a single bus system. If these pins are left floating, the E2, E1 and E0 pins will be internally pulled down to GND. Write Control (WCB): The Write Control input, when WCB is connected directly to VCC, all write operations to the memory are inhibited. When connected to GND, allows normal write operations. If the pin is left floating, the WCB pin will be internally pulled down to GND. 2.
