5. 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 (see Figure 5-1 ).
Data changes during SCL high periods will indicate a start or stop condition as defined below.
Figure 5-1.

START CONDITION: A high-to-low transition of SDA with SCL high is a start condition that must
precede any other command (see Figure 5-2 ).

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 (see Fig-
ure 5-2 ).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the
EEPROM in 8-bit words. . The EEPROM sends a “0” to acknowledge that it has received each
word. This happens during the ninth clock cycle.
STANDBY MODE: The AT24HC02B features a low-power standby mode that is enabled: (a)
upon power-up and (b) after the receipt of the Stop bit and the completion of any internal
operations.
