Description
The M41T66 serial access TIMEKEEPER is a low power serial RTC with a built-in
32.768 kHz oscillator (external crystal controlled). Eight registers (see Table 2 on page 15)
are used for the clock/calendar function and are configured in binary coded decimal (BCD)
format. An additional 8 registers provide status/control of alarm, square wave, calibration,
and watchdog functions. 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.
Functions available to the user include a time-of-day clock/calendar, alarm interrupts,
programmable square wave output, and watchdog output. 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 M41T66 is supplied in a 16-pin QFN.
