PAGE WRITE OPERATION

The 24LLC16 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 24LLC166 responds with an ACK each time

it receives a complete byte of data (see Figure 5-10).

Figure 5-10. Page Write Operation

The 24LLC16 automatically increments the word address pointer each time it receives a complete data byte.

When one byte is received, the internal word address pointer increments to the next address so that 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 24LLC16 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 24LLC16 writes the received data to

the corresponding EEPROM address.

During a page write operation, all inputs are disabled and there would be no response to additional requests from

the master until the internal write cycle is completed.
