Description
The AT24C512 provides 524,288 bits of serial electrically erasable and programmable
read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device’s
cascadable feature allows up to 4 devices to share a common 2-wire bus. The device
is optimized for use in many industrial and commercial applications where low-power
and low-voltage operation are essential. The devices are available in space-saving
8-pin PDIP, 20-pin JEDEC SOIC, 8-pin Leadless Array (LAP), and 8-ball dBGA
pack-
ages. In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to
5.5V) and 1.8V (1.8V to 3.6V) 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 (A1, A0): The A1 and A0
pins are device address inputs that are hardwired or left not
connected for hardware compatibility with AT24C128/256.
When the pins are hardwired, as many as four 512K
devices may be addressed on a single bus system (device
addressing is discussed in detail under the Device
Addressing section). When the pins are not hardwired, the
default A1 and A0 are zero.
WRITE PROTECT (WP): The write protect input, when tied
to GND, allows normal write operations. When WP is tied
high to V
CC
, all write operations to the memory are inhib-
ited. If left unconnected, WP is internally pulled down to
GND. Switching WP to V
CC
prior to a write operation cre-
ates a software write protect function.
Memory Organization
AT24C512, 512K SERIAL EEPROM: The 512K is inter-
nally organized as 512 pages of 128-bytes each. Random
word addressing requires a 16-bit data word address.
Absolute Maximum Ratings*
Operating Temperature.................................. -55°C to +125°C
*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.
Storage Temperature ..................................... -65°C to +150°C
Voltage on Any Pin
with Respect to Ground .....................................-1.0V to +7.0V
Maximum Operating Voltage .......................................... 6.25V
DC Output Current........................................................ 5.0 mA
