Preliminary Information  
CAT1021, CAT1022, CAT1023  
Page Write  
The CAT1021/22/23 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, the CAT1021/22/23 will respond with  
anacknowledgeandinternallyincrementthelowerorder  
address bits by one. The high order bits remain  
unchanged.  
IftheMastertransmitsmorethan16bytesbeforesending  
theSTOPcondition, theaddresscounterwrapsaround,’  
and previously transmitted data will be overwritten.  
When all 16 bytes are received, and the STOP condition  
has been sent by the Master, the internal programming  
cycle begins. At this point, all received data is written to  
the CAT1021/22/23 in a single write cycle.
