AT24C01
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 (refer to
Data Validity timing diagram). 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
which must precede any other command (refer to Start and Stop Definition timing
diagram).
STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition
which terminates all communications. After a read sequence, the stop command will
place the EEPROM in a standby power mode (refer to Start and Stop Definition timing
diagram).
ACKNOWLEDGE: All addresses and data words are serially transmitted to and from
the EEPROM in 8-bit words. Any device on the system bus receiving data (when com-
municating with the EEPROM) must pull the SDA bus low to acknowledge that it has
successfully received each word. This must happen during the ninth clock cycle after
each word received and after all other system devices have freed the SDA bus. The
EEPROM will likewise acknowledge by pulling SDA low after receiving each address or
data word (refer to Acknowledge Response from Receiver timing diagram).
STANDBY MODE: The AT24C01 features a low power standby mode which is enabled:
(a) upon power-up and (b) after the receipt of the STOP bit and the completion of any
internal operations.
MEMORY RESET: After an interruption in protocol, power loss or system reset, any 2-
wire part can be reset by following these steps:
(a) Clock up to 9 cycles, (b) look for SDA high in each cycle while SCL is high and then
(c) create a start condition as SDA is high.
