AC Characteristics
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.
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.
After an interruption in protocol, power loss or system reset, any 2-wire part can be reset by
following these steps:
