Device Operation
CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an external device. Data on the SDA pin
may change only during SCL low time periods (refer to Figure 2). Data changes during SCL high periods will indicate a
start or stop condition as defined below.

START CONDITION: A high-to-low transition of SDA with SCL high is a start condition that must precede any other
command (refer to Figure 3).

STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence, the stop
command will place the EEPROM in a standby power mode (refer to Figure 3).
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.
