*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.

2. Pin Description
SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM
device and negative edge clock data out of each device.
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 (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are
hard wired or left not connected for hardware compatibility with other AT24CXX devices. When
the pins are hardwired, as many as eight 64K devices may be addressed on a single bus system
(device addressing is discussed in detail under the Device Addressing section). If the pins are
left floating, the A2, A1 and A0 pins will be internally pulled down to GND if the capacitive cou-
