Description
The M41T6x serial access TIMEKEEPER is a low power serial RTC with a built-in
32.768 kHz oscillator (external crystal controlled). Eight registers (see
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, 32 KHz output, calibration,
and watchdog functions. Addresses and data are transferred serially via a two line, bi-
directional 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
(M41T62/65), 32 KHz output (M41T64), programmable square wave output
(M41T62/63/64), and watchdog output (M41T63/65). 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 M41T6x is supplied in a 16-pin QFN.
