  • The M24512 is a 512-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) organized as 64 K × 8 bits.

    The M24512-W can operate with a supply voltage from 2.5 V to 5.5 V, the M24512-R can operate with a supply voltage from 1.8 V to 5.5 V and the M24512-DF can operate with a supply voltage from 1.7 V to 5.5 V. All these devices operate with a clock frequency of 1 MHz (or less) over an ambient temperature range of -40 °C / +85 °C.
    The M24512-D offers an additional page, named the Identification Page (128 byte). 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 all I2C bus modes:
      • 1 MHz
      • 400 kHz
      • 100 kHz
    • Memory array:

      • Page size: 128 byte
      • Additional Write lockable page (M24512-D order codes)
    • Single supply voltage and high speed:
      • 1 MHz clock from 1.7 V to 5.5 V
    • Write:
      • Byte Write within 5 ms
      • Page Write within 5 ms
    • Operating temperature range:
      • from -40 °C up to +85 °C
    • Random and sequential Read modes
    • Write protect of the whole memory array
    • Enhanced ESD/Latch-Up protection
    • More than 4 million Write cycles
    • More than 200-years data retention
    • Packages
