WRITE Mode
In this mode the master transmitter transmits to the M41T11 slave receiver. Bus protocol is shown in
Figure 8
. Following the START condition and slave address, a logic '0' (R/W = 0) is placed on the bus and
indicates to the addressed device that word address An will follow and is to be written to the on-chip
address pointer. The data word to be written to the memory is strobed in next and the internal address
pointer is incremented to the next memory location within the RAM on the reception of an acknowledge
clock. The M41T11 slave receiver will send an acknowledge clock to the master transmitter after it has
received the slave address and again after it has received the word address and each data byte (see
Figure 7 on page 10
).
2.4
Data retention Mode
With valid V
CC
applied, the M41T11 can be accessed as described above with read or write cycles.
Should the supply voltage decay, the M41T11 will automatically deselect, write protecting itself when V
CC
falls (see
Figure 15
).
