6 / 44 page Description M41T62/63/64/65 6/44 Doc ID 10397 Rev 19 1 Description The M41T6x is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator. Eight registers 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, 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 (M41T62/65), 32 KHz output (M41T62/63/64), 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 two very small packages: a tiny, 3 mm x 3 mm 16-pin QFN which requires a user-supplied 32 KHz crystal, and an ultra-small 1.5 mm x 3.2 mm LCC with embedded crystal - no external crystal is required.
