Description

The ACE24AC512 series are 524,288 bits of serial Electrical Erasable and Programmable Read Only

Memory, commonly known as EEPROM. They are organized as 65,536 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.
