DEVICE OPERATION
The X24F064/032/016 supports a bidirectional bus ori-
ented protocol. The protocol defines any device that
sends data onto the bus as a transmitter, and the re-
ceiving device as the receiver. The device controlling
the transfer is a master and the device being controlled
is the slave. The master will always initiate data trans-
fers, and provide the clock for both transmit and receive
operations. Therefore, the X24F064/032/016 will be
considered a slave in all applications.
Clock and Data Conventions
Data states on the SDA line can change only during
SCL LOW. SDA state changes during SCL HIGH are
reserved for indicating start and stop conditions. Refer
to Figures 1 and 2.
Start Condition
All commands are preceded by the start condition,
which is a HIGH to LOW transition of SDA when SCL is
HIGH. The X24F064/032/016 continuously monitors
the SDA and SCL lines for the start condition and will
not respond to any command until this condition has
been met.
