Ordering information
Serial Clock (SCL):
data out of each device.
Serial Data (SDA):
wire-ORed with any number of other open-drain or open-collector devices.
Device/Page Addresses (A2, A1, A0):
as eight 2K devices may be addressed on a single bus system (device addressing is discussed in
detail under the Device Addressing section).
may be addressed on a single bus system. The A0 pin is a no connect.
addressed on a single bus system. The A0 and A1 pins are no connects.
single bus to one. The A0, A1 and A2 pins are no connects.
Write Protect (WP):
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.
Write Protect Description
The ACE24(L)C02/04/08/16 has a Write Protect pin that provides hardware data protection. The Write Protect
WP Pin Status
The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock
The SDA pin is bi-directional for serial data transfer. This pin is open-drain driven and may be
The A2, A1 and A0 pins are device address inputs that are hard wired for the ACE24(L)C02, As many
The ACE24(L)C04 uses the A2 and A1 inputs for hard wire addressing and a total of four 4K devices
The ACE24(L)C08 only uses A2 input for hardwire addressing and a total of two 8K devices may be
The ACE24(L)C16 does not use the device address pins, which limits the number of devices on a
