Write Operation  
Byte/Page Write:  
If a write operation is entered (R/W=0) and an acknowledgement is sent, then the next sequence requires an  
8-bit data word address. After an acknowledgement is received from this word address, the 1st byte of data  
can be loaded. The device will send an acknowledgement after each byte to confirm the transmission.  
To being the write cycle, a STOP condition must be issued ( refer to Figure 7). Both byte and page write  
operations are supported, so the STOP condition can be issued after the 1st byte or the last byte in the page.  
When the STOP condition occurs, an internal time is started, all inputs are disabled, and the EEPROM will  
not respond to any more commands until the write cycle is completed.  
Note: The number of bytes in a page depends on the density used. If 1K density is used, then the page size  
is 8 bytes. In contrast, if the 16K density is used, then the page size is 16 bytes. Refer to the Memory  
Organization section for more details.  
The internal page counter is incremented after each byte received, but the row location of the memory page  
will always remain the same. Therefore the device will wrap around to the 1st byte in the page after the last  
byte in the page is received. Any further data loaded into the page buffer will overwrite the previous data  
loaded.  
Acknowledge Polling:  
After the STOP condition is issued, the write cycle begins. Acknowledge polling can be initiated by  
sending a START condition followed by the device address word. If the EEPROM has completed the  
internal write cycle and returned to standby mode, the device will respond by sending back an  
acknowledgement by pulling the SDA pin low. Otherwise, the sequence will be ignored and no  
acknowledgement will be sent.  
Read Operations  
There are three types of read operations: current address read, random address read, and sequence read. A  
random address read can be considered a current address read operation with an additional sequence in the  
beginning to load a different address into the internal counter. A sequential read occurs when subsequent  
bytes are clocked out after a current address read or random address read occurs.
