ACE24AC128
Two-wire Serial EEPROM
Description
The ACE24AC128 series are 131,072 bits of serial Electrical Erasable and Programmable Read Only
Memory, commonly known as EEPROM. They are organized as 16,384 words of 8 bits (one byte) each.
The devices are fabricated with proprietary advanced CMOS process for low power and low voltage
applications. These devices are available in standard 8-lead DIP, 8-lead SOP, 8-lead MSOP, 8-lead
TSSOP and 8-lead USON3*2-8 packages. A standard 2-wire serial interface is used to address all read
and write functions. Our extended V_CC range (1.8V to 5.5V) devices enables wide spectrum of
applications.
