24LC64-E/SN Memory by Microchip Technology

64Kb I2C compatible 2-wire Serial EEPROM


The Microchip Technology Inc. 24LC64 is a 64Kb I2C™ compatible Serial EEPROM. The device is organized as a single block of 8K x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 2.5V, with standby and active currents of only 1 µA and 1 mA, respectively. It has been developed for advanced, lowpower applications such as personal communications or data acquisition. The 24LC64 also has a page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for up to 512 Kbits address space. The 24LC64 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, DFN, TDFN and MSOP packages. The 24LC64 is also available in the 5-lead SOT-23 package.
