The M95M04-DR device is electrically erasable programmable memory (EEPROM) organized as 524288 x 8 bits, accessed through the SPI bus.

The M95M04-DR can operate with a supply range from 1.8 to 5.5 V, and is guaranteed over the -40 °C/+85 °C temperature range.

The M95M04-DR offer an additional page, named the identification page (512 bytes). The identification page can be used to store sensitive application parameters that can be (later) permanently locked in read-only mode.
