AT24C02A
Description
The AT24C02A/04A provides 2048/4096 bits of serial electrically erasable and program-
mable read-only memory (EEPROM) organized as 256/512 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 is available in
space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP and 8-lead TSSOP pack-
ages 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.

*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.

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 must be hardwired for the AT24C02A. As many as eight 2K devices
may be addressed on a single bus system. (Device addressing is discussed in detail
under Device Addressing, page 8).
