Key Features

  • 64Kbit (8Kx8) I2C serial EEPROM with 400kHz clock and I2C control byte 1010DDDR for multi-device bus addressing
  • 1 million write/erase cycle endurance with 200-year minimum data retention ensuring long-term non-volatile storage reliability
  • 2.5V operation in an SOIC-8 package enabling integration in low-voltage microcontroller and embedded systems

Applications

The 24LC64-I/SN is widely used for non-volatile storage of configuration data, calibration parameters, and user settings in microcontroller-based embedded systems. Its I2C interface and low 2.5V operating voltage make it compatible with modern low-power MCUs, IoT sensors, and communication modules. The high endurance and long data retention make it ideal for data logging, medical devices, and industrial electronics requiring persistent reliable memory.
