Figure 7. Memory Protection
of data, which are each acknowledged by the mem-
ory. After each byte is transfered, the internal byte
address counter (4 least significant bits only) is
incremented. The transfer is terminated by the
master generating a STOP condition. Care must be
taken to avoid address counter ’roll-over’ which
could result in data being overwritten. Note that, for
any write mode, the generation by the master of the
STOP condition starts the internal memory pro-
gram cycle. All inputs are disabled until the comple-
tion of this cycle and the memory will not respond
to any request.
Minimizing System Delays by Polling On ACK.
During the internal write cycle, the memory discon-
nects itself from the bus in order to copy the data
from the internal latches to the memory cells. The
maximum value of the write time (t
W
) is given in the
AC Characteristics table, since the typical time is
shorter, the time seen by the system may be re-
duced by an ACK polling sequence issued by the
master.
