Application Scenarios & Design Considerations

Advanced SPI Serial E 2 PROM with Block Lock TM Protection

Alternative Part Number

  • CAT25040VI-GT3 --: 4Kb SPI EEPROM in the same small SOIC package, functionally compatible with the X25642S serial EEPROM and widely available.
  • M95040-WMN6TP --: 4Kb SPI EEPROM with compatible serial interface and supply range, suitable drop-in replacement for legacy Xicor parts.
  • 25LC040A-I/SN --: 4Kb SPI EEPROM from Microchip's 25LC series, pin-compatible and well supported for long-term availability.
  • M24512-WMN6TP --: 512 Kbit I2C serial EEPROM in SOIC-8, functionally equivalent to the X25642 with compatible pinout and supply voltage.
  • 24LC512-I/SN --: 512 Kbit I2C EEPROM in SOIC-8, widely available drop-in replacement with matching interface and memory density.
  • CAT24C512WI-GT3 --: 512 Kbit I2C serial EEPROM in SOIC-8, comparable specifications and pin-compatible alternative for the X25642S.
