Application Scenarios & Design Considerations

SPI Serial E2PROM with Block LockTM Protection

Alternative Part Number

  • M95040-WMN6TP --: 4Kbit SPI EEPROM in SOIC-8 with 2.5V to 5.5V supply, functionally equivalent to the X25040 and widely available.
  • 25LC040A-I/SN --: 4Kbit SPI serial EEPROM in SOIC-8, drop-in compatible pinout and protocol, supports 2.5V operation.
  • CAT25040VI-GT3 --: 4Kbit SPI EEPROM in SOIC-8 with low-voltage 1.8V-5.5V range, suitable replacement for the X25040SI-2.7.
