M24256E-F 256-Kbit serial I2C bus EEPROM

1 Description The M24256E-F is a 256-Kbit I2C-compatible EEPROM (electrically erasable programmable read only memory) organized as 32 K × 8 bits. The M24256E-F can operate with a supply voltage from 1.65 V to 5.5 V, with a clock frequency of 1 MHz (or less), over an ambient temperature range of -40 °C/+85 °C. It can also operate down to 1.6 V, under some .
