M24256X-F 256-Kbit serial I2C bus EEPROM

1 Description The M24256X-F is a 256-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) organized as 32 K × 8 bits. The M24256X-F can operate with a supply voltage from 1.65 V to 3.6 V, with a clock frequency up to 1 MHz, over an ambient temperature range from -40 °C to +85 °C. It can also operate down to 1.6 V, under some restricting .
