Description
The AT24C02A/04A/08A provides 2048/4096/8192 bits of serial electrically erasable
and programmable read only memory (EEPROM) organized as 256/512/1024 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
AT24C02A/04A/08A is available in space saving 8-pin PDIP, 8-pin and 14-pin JEDEC
SOIC, and 8-pin TSSOP packages and is accessed via a 2-wire serial interface. In
addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), 2.5V
(2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

Block Diagram
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 AT24C02A. 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).
The AT24C04A 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 con-
nect.
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.
WRITE PROTECT (WP):
The AT24C02A/04A/08A 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

Memory Organization
AT24C02A, 2K SERIAL EEPROM:
Internally organized
with 256 pages of 1-byte each, the 2K requires an 8 bit
data word address for random word addressing.
AT24C04A, 4K SERIAL EEPROM:
The 4K is internally
organized with 256 pages of 2-bytes each. Random word
addressing requires a 9 bit data word address.
AT24C08A, 8K SERIAL EEPROM:
The 8K is internally
organized with 4 blocks of 256 pages of 4-bytes each.
Random word addressing requires a 10 bit data word
address.
