ACE24LA1024A

Two-wire Serial EEPROM

VER 1.3

1

Description

The ACE24LA1024A provides 1048576 bits of serial electrically erasable and programmable read-

only memory (EEPROM), organized as 131072 words of 8 bits each.

The device is optimized for use in many industrial and commercial applications where low-power and

low-voltage operation are essential.

The ACE24LA1024A offers an additional page, named the Identification Page (256 bytes). The

Identification Page can be used to store sensitive application parameters which can be (later)

permanently locked in Read-only mode.
