Figure 1. Block Diagram
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 AT24HC02B. 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).
WRITE PROTECT (WP): The AT24HC02B has a WP pin that provides hardware data
protection. The WP pin allows normal read/write operations when connected to ground
(GND). When the WP pin is connected to V
and operates as shown.

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.
