CAT24CXX1/XX2  
Acknowledge Polling  
protected and becomes read only. The CAT24CXXX  
will accept both slave and byte addresses, but the  
memory location accessed is protected from program-  
ming by the device's failure to send an acknowledge  
after the first byte of data is received.  
Disabling of the inputs can be used to take advantage of  
the typical write cycle time. Once the stop condition is  
issued to indicate the end of the host’s write operation,  
CAT24CXXX initiates the internal write cycle. ACK poll-  
ing can be initiated immediately. This involves issuing  
the start condition followed by the slave address for a  
writeoperation. IfCAT24CXXXisstillbusywiththewrite  
operation, no ACK will be returned. If  
CAT24CXXX has completed the write operation, an  
ACK will be returned and the host can then proceed with  
the next read or write operation.  
READ OPERATIONS  
The READ operation for the CAT24CXXX is initiated in  
the same manner as the write operation with one excep-  
tion, that R/W bit is set to one. Three different READ  
operations are possible: Immediate/Current Address  
READ,Selective/Random READandSequential READ.  
WRITE PROTECTION  
The Write Protection feature allows the user to protect  
against inadvertent programming of the memory array.  
If the WP pin is tied to VCC, the entire memory array is
