Application Scenarios & Design Considerations

1 Kbit x8 Dual Mode Serial EEPROM for VESA PLUG & PLAY

Alternative Part Number

  • 24LC21A --: Pin-compatible 2-wire serial EEPROM with similar 1Kbit density and I2C interface, widely available and commonly used as a direct substitute.
  • AT24C21 --: I2C serial EEPROM in the same 1Kbit class with compatible addressing and voltage range, suitable for drop-in replacement in most designs.
  • CAT24C21 --: Low-power I2C serial EEPROM offering equivalent memory density and interface, a viable alternative when the original ST part is unavailable.
