Functional Description
Start Condition
A high-to-low transition of the SDA with the SCL high is needed in order to start read, write operation (See start
condition and stop condition).
Stop Condition
A low-to-high transition of the SDA with the SCL high is a stop condition. The stand-by operation starts after a read
sequence by a stop condition. In the case of write operation, a stop condition terminates the write data inputs and place
the device in a internally-timed write cycle to the memories. After the internally-timed write cycle which is specified as
t WC , the device enters a standby mode (See write cycle timing).

Acknowledge
All addresses and data words are serially transmitted to and from in 8-bit words. The receiver sends a zero to
acknowledge that it has received each word. This happens during ninth clock cycle. The transmitter keeps bus open to
receive acknowledgment from the receiver at the ninth clock. In the write operation, EEPROM sends a zero to
acknowledge after receiving every 8-bit words. In the read operation, EEPROM sends a zero to acknowledge after
receiving the device address word. After sending read data, the EEPROM waits acknowledgment by keeping bus open.
If the EEPROM receives zero as an acknowledge, it sends read data of next address. If the EEPROM receives
acknowledgment "1" (no acknowledgment) and a following stop condition, it stops the read operation and enters a
stand-by mode. If the EEPROM receives neither acknowledgment "0" nor a stop condition, the EEPROM keeps bus
open without sending read data.
