24LLC08
8K-Bit Serial EEPROM
PAGE WRITE OPERATION
The 24LLC08 can also perform 16-byte page write operation. A page write operation is initiated in the same way
as a byte write operation. However, instead of finishing the write operation after the first data byte is transferred,
the master can transmit up to 15 additional bytes. The 24LLC08 responds with an ACK each time it receives a
complete byte of data (see Figure 3-10).

Figure 3-10. Page Write Operation
The 24LLC08 automatically increments the word address pointer each time it receives a complete data bytes.
When one byte has been received, the internal word address pointer increments to the next address and the
next data byte can be received.
If the master transmits more than 16 bytes before it generates a stop condition to end the page write operation,
the 24LLC08 word address pointer value “rolls over” and the previously received data is overwritten. If the
master transmits less than 16 bytes and generates a stop condition, the 24LLC08 writes the received data to
the corresponding EEPROM address.
During a page write operation, all inputs are disabled and there is no response to additional requests from the
master until the internal write cycle is completed.
