Description
The AT24C01A/02/04/08A/16A provides 1024/2048/4096/8192/16384 bits of serial
electrically erasable and programmable read-only memory (EEPROM) organized as
128/256/512/1024/2048 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low-power and low-voltage operation
are essential. The AT24C01A/02/04/08A/16A is available in space-saving 8-lead
PDIP,
8-lead JEDEC SOIC,
8-lead Ultra T hin Mini-MAP (MLP 2x3)
, 5-lead SOT23
(AT24C01A/AT24C02/AT24C04), 8-lead TSSOP, and 8-ball dBGA2 packages and is
accessed via a Two-wire serial interface. In addition, the entire family is available in
2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

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

AT24C01A/02/04/08A/16A
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 AT24C01A and the AT24C02. As many as
eight 1K/2K devices may be addressed on a single bus system (device addressing is
discussed in detail under the Device Addressing section).
The AT24C04 uses the A2 and A1 inputs for hard wire addressing and a total of four 4K
devices may be addressed on a single bus system. The A0 pin is a no connect and can
be connected to ground.
The AT24C08A only uses the A2 input for hardwire addressing and a total of two 8K
devices may be addressed on a single bus system. The A0 and A1 pins are no connects
and can be connected to ground.
The AT24C16A does not use the device address pins, which limits the number of
devices on a single bus to one. The A0, A1 and A2 pins are no connects and can be
connected to ground.
WRITE PROTECT (WP):
The AT24C01A/02/04/08A/16A has a Write Protect pin that
provides hardware data protection. The Write Protect pin allows normal Read/Write
operations when connected to ground (GND). When the Write Protect pin is connected
to V
CC
, the write protection feature is enabled and operates as shown in Table 2.

Memory Organization
AT24C01A, 1K SERIAL EEPROM:
Internally organized with 16 pages of 8 bytes each,
the 1K requires a 7-bit data word address for random word addressing.
AT24C02, 2K SERIAL EEPROM:
Internally organized with 32 pages of 8 bytes each,
the 2K requires an 8-bit data word address for random word addressing.
AT24C04, 4K SERIAL EEPROM:
Internally organized with 32 pages of 16 bytes each,
the 4K requires a 9-bit data word address for random word addressing.
AT24C08A, 8K SERIAL EEPROM:
Internally organized with 64 pages of 16 bytes
each, the 8K requires a 10-bit data word address for random word addressing.
AT24C16A, 16K SERIAL EEPROM:
Internally organized with 128 pages of 16 bytes
each, the 16K requires an 11-bit data word address for random word addressing.
