LE24CB642MC ^{Two Wire Serial Interface EEPROM}
(64k EEPROM)
Overview
The LE24CB642MC 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

• 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)
