Description
The M41T8x are low power serial I2C real-time clocks with a built-in 32.768 kHz oscillator
(external crystal-controlled for the QFN16 and SO8 packages, embedded crystal for the
SOX18 package). Eight bytes of the register map (see Table2 on page21) are used for the
clock/calendar function and are configured in binary coded decimal (BCD) format. An
additional 17 bytes of the register map provide status/control of the two alarms, watchdog,
8-bit counter, and square wave functions. An additional seven bytes are made available as
user SRAM.
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 M41T8x 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 battery
when a power failure occurs.
Functions available to the user include a non-volatile, time-of-day clock/calendar, two alarm
interrupts, watchdog timer, programmable 8-bit counter, and square wave outputs. The eight
clock address locations contain the century, year, month, date, day, hour, minute, second,
and tenths/hundredths of a second in 24-hour BCD format. Corrections for 28, 29 (leap
year), 30, and 31 day months are made automatically. The M41T83 is supplied in either a
QFN16 (QA) or an SOX18 (MY), 300 mil SOIC which includes an embedded 32 KHz crystal.
The SOX18 package requires only a user-supplied battery to provide non-volatile operation.
The M41T82 is available only in an SO8 (M) package.
