AT24C01A/02/04/08A/16ANote: 1. This parameter is characterized and is not 100% tested (TA = 25°C).2. This parameter is characterized.Device Operation CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an exter-nal device. Data on the SDA pin may change only during SCL low time periods (see toFigure 4 on page 7). Data changes during SCL high periods will indicate a start or stopcondition as defined below.START CONDITION: A high-to-low transition of SDA with SCL high is a start conditionwhich must precede any other command (see to Figure 5 on page 7).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 powermode (see Figure 5 on page 7).ACKNOWLEDGE: All addresses and data words are serially transmitted to and from theEEPROM in 8-bit words. The EEPROM sends a “0” to acknowledge that it has receivedeach word. This happens during the ninth clock cycle.STANDBY MODE: The AT24C01A/02/04/08A/16A features a low-power standby modewhich is enabled: (a) upon power-up and (b) after the receipt of the STOP bit and thecompletion of any internal operations.Table 5.
