Application Scenarios & Design Considerations

1K/2K 2-Wire CMOS Serial EEPROM

Alternative Part Number

  • AT24C01 --: Pin-compatible 1Kbit I2C EEPROM with the same 8-pin layout and I2C protocol, widely available and directly interchangeable in most designs.
  • 24C01 --: Standard 1Kbit I2C serial EEPROM matching the HT24LC01 function and pinout, a common second-source option.
  • CAT24C01 --: 1Kbit I2C EEPROM with compatible pinout and voltage range, suitable as a drop-in replacement for the HT24LC01.
