Description

The ACE24AC1024E series are 1,048,576 bits of serial Electrical Erasable and Programmable Read

Only Memory, commonly known as EEPROM. They are organized as 131,072 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 and 8-lead SOP A standard 2-wire serial

enables wide spectrum of applications.
