Ordering number : ENA1440A
LE24L042CS
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 I²C memory
protocol, therefore it is best suited for application that requires small-scale re-writable nonvolatile parameter memory.
Functions
• Capacity: 4k bits (512 × 8 bits)
• Single supply voltage: 1.7V to 3.6V
• Interface: Two wire serial interface (I²C Bus*)
• Operating clock frequency: 400kHz
• Low power consumption
: Standby: 2μA (max)
: Active (Read): 0.5mA (max)
• Automatic page write mode: 16 Bytes
• Read mode: Sequential read and random read
• Erase/Write cycles: 10⁵ cycles
• Data Retention: 20 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.
• Package: LE24L042CS-LV : WLP4
