terminates data transmission and waits for a STOP
condition.
WRITE OPERATIONS
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
the Slave generates an acknowledge, the Master sends
two 8-bit address words that are to be written into the
address pointers of the CAT24WC256. After receiving
another acknowledge from the Slave, the Master device
transmits the data to be written into the addressed
memory location. The CAT24WC256 acknowledges
once more and the Master generates the STOP condi-
tion. At this time, the device begins an internal program-
ming cycle to nonvolatile memory. While the cycle is in
progress, the device will not respond to any request from
the Master device.
Page Write
The CAT24WC256 writes up to 64 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 63 additional bytes. After each byte has
been transmitted, CAT24WC256 will respond with an
acknowledge, and internally increment the six low order
address bits by one. The high order bits remain un-
changed.
If the Master transmits more than 64 bytes before sending
the STOP condition, the address counter ‘wraps around’,
and previously transmitted data will be overwritten.
When all 64 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 CAT24WC256 in a single write cycle.
Acknowledge Polling
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,
CAT24WC256 initiates the internal write cycle. ACK
polling can be initiated immediately. This involves issu-
ing the start condition followed by the slave address for
a write operation. If CAT24WC256 is still busy with the
write operation, no ACK will be returned. If
CAT24WC256 has completed the write operation, an
ACK will be returned and the host can then proceed with
the next read or write operation.
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
protected and becomes read only. The CAT24WC256
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.
