SUMMARY DESCRIPTION
The M41T6x Serial Access TIMEKEEPER
is a
low power Serial RTC with a built-in 32.768 kHz
oscillator (external crystal controlled). Eight regis-
ters (see
Table 3., page 14
) are used for the clock/
calendar function and are configured in binary
coded decimal (BCD) format. An additional 8 reg-
isters provide status/control of Alarm, 32KHz out-
put,
Calibration,
and
Addresses and data are transferred serially via a
two line, bi-directional I
2
C interface. The built-in
address register is incremented automatically af-
ter each WRITE or READ data byte.

functions.
Functions available to the user include a time-of-
day clock/calendar, Alarm interrupts (M41T62/65),
32KHz output (M41T64), programmable Square
Wave output (M41T62/63/64), and Watchdog out-
put (M41T63/65). The eight clock address loca-
tions 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 M41T6x is supplied in a 16-pin QFN.
