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 bi-directional 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 ACE24LC02, 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).

Write Protect (WP):

The ACE24LC02 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 pin is conceded to Vcc

the write protection feature is enabled.
