The M95040-WMN6P is a 4kb standard serial Electrically Erasable Programmable Memory (EEPROM) with high-speed clock. The serial EEPROM is the most flexible type of non-volatile memory. For very heavy cycling requirements with many parameters and high temperatures, EEPROM is the ideal product for your parameter storage needs. It is organized as 128/256/512 x 8-bit respectively, accessed through the SPI bus.
