Two-wire Serial EEPROM
Description
The ACE24(L)C02/04/08/16 provides 2048 / 4096 / 8192 / 16384 bits of serial electrically erasable and
programmable read-only memory (EEPROM) organized as 256/512/1024/2048 words of 8 bits each. The device is
optimized for use in many industrial and commercial applications where low-power and low-voltage
operations are essential.

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 ACE24(L)C02, 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).
The ACE24(L)C04 uses the A2 and A1 inputs for hard wire addressing and a total of four 4K devices
may be addressed on a single bus system. The A0 pin is a no connect.
The ACE24(L)C08 only uses A2 input for hardwire addressing and a total of two 8K devices may be
addressed on a single bus system. The A0 and A1 pins are no connects.
The ACE24(L)C16 does not use the device address pins, which limits the number of devices on a
single bus to one. The A0, A1 and A2 pins are no connects.
Write Protect (WP):
The ACE24(L)C02/04/08/16 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.
