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/PAGE ADDRESSES (A2, A1, A0):
The A2, A1
and A0 pins are device address inputs that are hard wired
for the AT34C02. As many as eight 2K devices may be
addressed on a single bus system (device addressing is
discussed in detail under the Device Addressing section).
WRITE PROTECT (WP):
The AT34C02 has a Write Pro-
tect pin that provides hardware data protection. The Write
Protect pin allows normal read/write operations when con-
nected to ground (GND) or when left floating. When the
Write Protect pin is connected to V
CC
, the write protection
feature is enabled for the entire array. The write protection
modes are shown in the following table.

*NOTICE:
Stresses beyond those listed under
“

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.
