  • 1.6V to 5.5V wide limit of operating voltage, possible FAST MODE 400KHz operation
  • Page Write Mode useful for initial value write at factory shipment
  • Self-timed Programming Cycle
  • Low Current Consumption
  • Prevention of Write Mistake
    Write (Write Protect) Function Added
    Prevention of Write Mistake at Low Voltage
  • More than 1 million write cycles
  • More than 40 years data retention
  • Noise filter built in SCL / SDA terminal
  • Initial delivery state FFh
