  • The M95M04 devices are electrically erasable programmable memories (EEPROMs) organized as 524288 x 8 bits, accessed through the SPI bus.

    The M95M04 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 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.

    Key Features

    • Compatible with the serial peripheral interface (SPI) bus
    • Memory array
      • 4 Mbit (512 Kbytes) of EEPROM
      • Page size: 512 bytes
      • Additional write lockable page (Identification page)
    • Write time
      • Byte Write within 5 ms
      • Page Write within 5 ms
    • Write protect
      • quarter array
      • half array

    • Max clock frequency: 10 MHz
    • Single supply voltage: 1.8 V to 5.5 V
    • Operating temperature range: from -40 °C up to +85 °C
    • Enhanced ESD protection (up to 4 kV in human body model)
    • More than 4 million Write cycles
    • More than 40-year data retention
    • Packages
      • SO8N (ECOPACK2)
      • TSSOP8 (ECOPACK2)
      • WLCSP (ECOPACK2)
