M41T81
Operation
Doc ID 7529 Rev 10
2.3
WRITE mode
In this mode the master transmitter transmits to the M41T81 slave receiver. Bus protocol is
shown in Figure 9 on page 11. 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
address location on the reception of an acknowledge clock. The M41T81 slave receiver will
send an acknowledge clock to the master transmitter after it has received the slave address
see Figure 6 on page 10 and again after it has received the word address and each data
byte.
2.4
Data retention mode
With valid VCC applied, the M41T81 can be accessed as described above with READ or
WRITE Cycles. Should the supply voltage decay, the power input will be switched from the
VCC pin to the battery when VCC falls below the battery backup switchover voltage (VSO). At
this time the clock registers will be maintained by the attached battery supply. On power-up,
For a further, more detailed review of lifetime calculations, please see application note
AN1012.
