  • The M95010/ M95020/M95040 devices (M950x0) are electrically erasable programmable memories (EEPROMs) organized as 128/256/512 x 8 bits respectively, accessed through the SPI bus.

    The M950x0-W can operate with a supply voltage from 2.5 V to 5.5 V, the M950x0-R can operate with a supply voltage from 1.8 V to 5.5 V, and the M950x0-DF can operate with a supply voltage from 1.7 V to 5.5 V, over an ambient temperature range of -40 °C / +85 °C.
    The M950x0-DF offers an additional page, named the Identification Page (16 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.

    Key Features

    • Compatible with SPI bus serial interface (Positive clock SPI modes)
    • Single supply voltage:
      • 2.5 V to 5.5 V for M950x0-W
      • 1.8 V to 5.5 V for M950x0-R
      • 1.7 V to 5.5 V for M95040-DF
    • High-speed 20 MHz clock rate, 5 ms write time
    • Memory array:
      • 1/2/4 Kbit (128/256/512 bytes) of EEPROM
      • Page size: 16 bytes
      • Write protection by block: 1/4, 1/2 or whole memory
      • Additional Write lockable Page (Identification page)
    • Enhanced ESD protection
    • More than 4 million write cycles
    • More than 200-year data retention
    • Packages RoHS-compliant and Halogen-free (ECOPACK®)
