Application Scenarios & Design Considerations

CMOS 64K 2-WIRE SERIAL EEPROM

Alternative Part Number

  • AT24C64 --: Widely available 64Kbit I2C EEPROM with the same 24C64 addressing and pinout, making it a direct functional drop-in replacement.
  • 24LC64 --: Industry-standard 64Kbit I2C serial EEPROM with identical 8-pin layout and I2C protocol, suitable for direct substitution.
  • CAT24C64 --: 64Kbit I2C EEPROM with compatible pinout and voltage range, offering a second-source option for the Holtek device.
  • 24LC64-I/P --: Industry-standard 64Kbit I2C serial EEPROM, pin and function compatible with the HT24LC64 and widely available.
  • AT24C64D-PU --: 64Kbit I2C EEPROM with the same 8-pin DIP pinout and I2C protocol, a direct functional replacement.
  • CAT24C64WI --: 64Kbit I2C CMOS serial EEPROM offering equivalent memory density and interface, suitable as a drop-in alternative.
