... Die Sales: Wafer Form, Waffle Pack and Bumped Wafers Description The AT24C256C provides 262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 32,768 words of 8 bits each. The device’s cascadable feature allows up to eight devices to share a common two-wire bus ...

... ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The EEPROM sends a “0” during the ninth clock cycle to acknowledge that it has received each word. STANDBY MODE: The AT24C256C features a low-power standby mode that is enabled upon power-up and after the receipt of the stop bit and the completion of any internal operations. ...
