SUMMARY DESCRIPTION
The M41T00S Serial Access TIMEKEEPER
SRAM is a low power Serial RTC with a built-in
32.768kHz oscillator (external crystal controlled).
Eight bytes of the SRAM (see Table 2., page 11)
are used for the clock/calendar function and are
configured in binary coded decimal (BCD) format.
Addresses and data are transferred serially via a
two line, bi-directional I2C interface. The built-in
address register is incremented automatically af-
ter each WRITE or READ data byte.
The M41T00S has a built-in power sense circuit
which detects power failures and automatically
switches to the battery supply when a power fail-
ure occurs. The energy needed to sustain the
clock operations can be supplied by a small lithium
button supply when a power failure occurs. The
eight clock address locations contain the century,
year, month, date, day, hour, minute, and second
in 24 hour BCD format. Corrections for 28, 29
(leap year - valid until year 2100), 30 and 31 day
months are made automatically.
The M41T00S is supplied in either an 8-pin SOIC
or an 18-pin (MY), 300mil SOIC package which in-
cludes an embedded 32kHz crystal.
The 18-pin, embedded crystal SOIC requires only
a user-supplied battery to provide non-volatile op-
eration.
