Pin Description
The X24C16A does not use the device address pins. The A0, A1 and
A2 pins are no-connects.
The SDA pin is bidirectional for serial data transfer. This pin is
open-drain driven and may be wired-ORed with any number of other
open-drain or open collector devices.
The SCL input is used to positive edge clock data into each EEPROM
device and negative edge clock data out of each device.
The X24C16A has a WP pin that provides hardware data protection.
The WP pin allows normal read/write operations when connected
to ground (GND). When the WP pin is connected to Vcc, the write
protection feature is enabled.
