Advanced Information  
ACKNOWLEDGE  
location. The CAT24CXXX acknowledges once more  
and the Master generates the STOP condition. At this  
time,thedevicebeginsaninternalprogrammingcycleto  
nonvolatile memory. While the cycle is in progress, the  
device will not respond to any request from the Master  
device.  
Afterasuccessfuldatatransfer, eachreceivingdeviceis  
requiredtogenerateanacknowledge.TheAcknowledg-  
ing device pulls down the SDA line during the ninth clock  
cycle, signaling that it received the 8 bits of data.  
The CAT24CXXX responds with an acknowledge after  
receivingaSTARTconditionanditsslaveaddress. Ifthe  
device has been selected along with a write operation,  
it responds with an acknowledge after receiving each 8-  
bit byte.  
Page Write  
The 24CXXX writes up to 16 bytes of data in a single  
write cycle, using the Page Write operation. The page  
write operation is initiated in the same manner as the  
byte write operation, however instead of terminating  
after the initial byte is transmitted, the Master is allowed  
to send up to 15 additional bytes. After each byte has  
been transmitted, CAT24CXXX will respond with an  
acknowledge, and internally increment the lower order  
address bits by one. The high order bits remain un-  
changed.  
When the CAT24CXXX begins a READ mode it trans-  
mits 8 bits of data, releases the SDA line, and monitors  
the line for an acknowledge. Once it receives this ac-  
knowledge, the CAT24CXXX will continue to transmit  
data. IfnoacknowledgeissentbytheMaster, thedevice  
terminates data transmission and waits for a STOP  
condition.  
WRITE OPERATIONS  
If the Master transmits more than 16 bytes before  
sendingtheSTOPcondition,theaddresscounter‘wraps  
around’,andpreviouslytransmitteddatawillbeoverwrit-  
ten.  
Byte Write  
In the Byte Write mode, the Master device sends the  
START condition and the slave address information  
(with the R/W bit set to zero) to the Slave device. After  
theSlavegeneratesanacknowledge, theMastersends  
a 8-bit address that is to be written into the address  
pointers of the CAT24CXXX. After receiving another  
acknowledge from the Slave, the Master device trans-  
mits the data to be written into the addressed memory  
When all 16 bytes are received, and the STOP condi  
tion has been sent by the Master, the internal program-  
ming cycle begins. At this point, all received data is  
written to the CAT24CXXX in a single write cycle.
