reads the data to be a receiver. The device that
controls the data transfer is known as the master,
and the other as the slave. A data transfer can only
be initiated by the master, which will also provide
the serial clock for synchronization. The memory
device is always a slave device in all
communication.
Start Condition
START is identified by a high to low transition of
the SDA line while the clock, SCL, is stable in the
high state. A START condition must precede any
data transfer command. The memory device

START condition, and will not respond unless one
is given.
Stop Condition
STOP is identified by a low to high transition of the

communication between the memory device and
the bus master. A STOP condition at the end of a
Read command, after (and only after) a NoAck,
forces the memory device into its standby state. A
STOP condition at the end of a Write command
triggers the internal EEPROM write cycle.
Acknowledge Bit (ACK)
An acknowledge signal is used to indicate a
successful byte transfer. The bus transmitter,
whether it be master or slave, releases the SDA
bus after sending eight bits of data. During the 9
th
clock pulse period, the receiver pulls the SDA bus
low to acknowledge the receipt of the eight data
bits.
Data Input
During data input, the memory device samples the
SDA bus signal on the rising edge of the clock,
SCL. For correct device operation, the SDA signal
must be stable during the clock low-to-high
