Summary description

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 registers (see Table 3 on page 19) 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, 32KHz 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), 32KHz 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.
