  • The M24C64 is a 64-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) organized as 8 K × 8 bits.

    Over an ambient temperature range of -40 °C / +85 °C, the M24C64-W can operate with a supply voltage from 2.5 V to 5.5 V, the M24C64-R can operate with a supply voltage from 1.8 V to 5.5 V, and the M24C64-F and M24C64-DF can operate with a supply voltage from 1.7 V to 5.5 V ( the M24C64-F can also operate down to 1.6 V, under some restricting conditions).
    The M24C64-D offers an additional page, named the Identification Page (32 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:
      • 64 Kbit (8 Kbyte) of EEPROM
      • Page size: 32 byte
      • Additional Write lockable page (M24C64-D order codes)
    • Single supply voltage:
      • 1.7 V to 5.5 V over –40 °C / +85 °C
      • 1.6 V to 5.5 V over 0 °C / +85 °C
    • Write:
      • Byte Write within 5 ms
      • Page Write within 5 ms
    • 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
