3. Pin Description
5134E–SEEPR–3/08
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,
8).
WRITE PROTECT (WP): The AT24HC02B has a WP pin that provides hardware data protec-
tion. The WP pin allows normal read/write operations when connected to ground (GND). When
the WP pin is connected to V
