ACE24LA128A

Two-wire Serial EEPROM

VER 1.1

1

Description

The ACE24LA128A provides 131,072 bits of serial electrically erasable and programmable read-only

memory (EEPROM), organized as 16,384 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

ACE24LA128A is available in space-saving 8-lead PDIP, 8-lead SOP, and 8-lead TSSOP packages and is

accessed via a two-wire serial interface. In addition, the ACE24LA128A is available in 1.7V (1.7V to 5.5V)

version.
