  • This EEPROM device supports standard I²C instruction set.

    The M24128X-FCU is a 128-Kbit I2C-compatible EEPROM (electrically erasable PROgrammable memory) organized as 16 K × 8 bits and delivered in a 4-ball WLCSP package.
    The M24128X-FCU can operate with a supply voltage of 1.7 V to 5 V, over an ambient temperature range of -40 °C/+85 °C. It can also operate down to 1.6 V, under some restricting conditions
    The M24128X-FCU additionally offers an 8-bit chip enable register for the configurable device address (CDA), to configure by software up to eight possibilities of chip enable address, and the memory write protection, enabled by setting, always through software, the write protection bit.
