ACE24(L)C02/04/08/16
Technology
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.
