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

programming 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

issuedtoindicatetheendofthehost’swriteopration, the

CAT24CXXXinitiatestheinternalwritecycle.ACKpolling

can be initiated immediately. This involves issueing the

start condition followed by the slave address for a write

operation. If the CAT24CXXX is still busy with the write

operation, no ACK will be returned. If a write operation

hascompleted, anACKwillbereturnedandthehostcan

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

exception, that R/W bit is set to one. Three different

READ operations are possible: Immediate/Current

Address READ, Selective/Random READ and

Sequential READ.

WRITE PROTECTION

The Write Protection feature allows the user to protect

against inadvertent memory array programming. If the

WP pin is tied to V_CC, the entire memory array is
