WRITE Mode
In this mode the master transmitter transmits to
the M41T00S slave receiver. Bus protocol is
shown in Figure 11. Following the START condi-
tion 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 address location on the reception of an
acknowledge clock. The M41T00S slave receiver
will send an acknowledge clock to the master
transmitter after it has received the slave address
see Figure 8., page 8 and again after it has re-
ceived the word address and each data byte.
Data Retention Mode
With valid VCC applied, the M41T00S can be ac-
cessed as described above with READ or WRITE
Cycles. Should the supply voltage decay, the pow-
er input will be switched from the VCC pin to the
battery when VCC falls below the Battery Back-up
Switchover Voltage (VSO). At this time the clock
registers will be maintained by the attached bat-
tery supply. On power-up, when VCC returns to a
nominal value, write protection continues for tREC.
For a further, more detailed review of lifetime cal-
culations, please see Application Note AN1012.
