LE24LB642CS

61009 SY / 51309 SY 20090401-S00007 No.A1464-1/11

Ordering number : ENA1464A

CMOS IC

Two Wire Serial Interface

EEPROM (64k EEPROM)

Overview

The LE24LB642CS 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.

Functions

• Capacity: 64k bits (8k × 8 bits)

• Single supply voltage: 1.7V to 3.6V

• slave addresses: S2=0, S1=0, S0=0

• Operating clock frequency: 400kHz

• Low power consumption

: Standby: 2

μA (max)

: Active (Read): 0.5mA (max)

• Automatic page write mode: 32 Bytes

• Read mode: Sequential read and random read

• Data Retention: 10 years

• High reliability: Adopts SANYO’s proprietary symmetric memory array configuration (USP6947325)

Noise filters connected to SCL and SDA pins

Incorporates a feature to prohibit write operations under low voltage conditions.
