Device Operation for Synchronous Protocols  
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 on page 8). Data changes  
during SCL high periods will indicate a start or stop condition as defined below.  
START CONDITION:  
STOP CONDITION:  
ACKNOWLEDGE:  
A high-to-low transition of SDA with SCL high is a start condition which must precede any  
other command (see Figure 6 on page 8).  
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 Figure 6 on page 8).  
All addresses and data words are serially transmitted to and from the EEPROM in 8-bit  
words. The EEPROM sends a zero to acknowledge that it has received each word. This  
happens during the ninth clock cycle.  
MEMORY RESET:  
After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by  
following these steps:  
1. Clock up to 9 cycles.
