61009 SY /40809 SY 20090327-S00006 No.A1440-1/10

Ordering number : ENA1440A

CMOS IC

Two Wire Serial Interface EEPROM

(4k EEPROM)

Overview

The LE24L042CS is a 2-wire serial interface EEPROM. It realizes high speed and a high level reliability by

incorporating SANYO’s high performance CMOS EEPROM technology. This device is compatible with I

protocol, therefore it is best suited for application that requires small-scale re-writable nonvolatile parameter memory.
