This EEPROM device supports standard I²C instruction set.
The M24C64X is a 64-Kbit I2C-compatible EEPROM (electrically erasable PROgrammable memory) organized as 8 K × 8 bits and delivered in a 4-ball WLCSP package.
The M24C64X 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 M24C64X offers an additional 8-bit chip enable register for the configurable device address (CDA) and memory write protection feature.
Thanks to these two features, the device offers the configurable device address, authorizing, through software, to configure up to eight possibilities of chip enable address, and the write protection of the whole memory array, by setting, always through software, the software write protection bit.
