Description

The ACE24AC1024D 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, 8-lead SOP and 8-lead TSSOP

packages. A standard 2-wire serial interface is used to address all read and write functions. Our extended
