LE24CB642

www.DataSheet.co.kr Ordering number : ENA1330A CMOS IC LE24CB642 Overview Two Wire Serial Interface EEPROM (64k EEPROM) The LE24CB642 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: 64k bits (8k × 8 bits) Single supply voltage: 2.7V to 5.5V 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: 32 Bytes Read mode: Sequential read and random read Erase/Write cycles: 106 cycles (Page writing), 105 cycles (Byte writing) 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. * I2C Bus is a trademark of Philips Corporation. * This product is licensed from Silicon Storage Technology, Inc.
