Description
The M41T00S Serial Access TIMEKEEPER SRAM is a low power serial RTC with a built-
in 32.768 kHz oscillator (external crystal controlled). Eight bytes of the SRAM (see Table 2
on page 13) 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,
bidirectional I2C interface. The built-in address register is incremented automatically after
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 failure 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 an 8-pin SOIC.
