Preliminary Information
CAT1026, CAT1027
Doc No. 3010, Rev. E
Page Write
The CAT1026 and CAT1027 write up to 16 bytes of data
in a single write cycle, by 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 CAT1026 and CAT1027 will respond
with an acknowledge and internally increment the lower
order address bits by one. The high order bits remain
unchanged.
If the Master transmits more than 16 bytes before sending
the STOP condition, the address counter ‘wraps around,’
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 CAT1026 and CAT1027 in a single write cycle.
