  • The M41T60 is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator (external crystal controlled). Eight registers are used for the clock/calendar function and are configured in binary-coded decimal (BCD) format. Addresses and data are transferred serially via a two-line, bidirectional bus. The built-in address register is increased automatically after each WRITE or READ data byte.

    The eight clock address locations contain the century, year, month, date, day, hour, minute, and second in 24-hour BCD format. Corrections for 28-, 29- (leap year), 30-, and 31-day months are made automatically.
    The M41T60 is supplied in a 16-lead QFN package.

    Key Features

    • Counters for seconds, minutes, hours, day, date, month, years, and century
    • 32 KHz crystal oscillator integrating load capacitance and high crystal series resistance operation
    • Oscillator stop detection monitors clock operation
    • Serial interface supports I2C bus (400 kHz)
    • 350 nA timekeeping current at 3 V
    • Low operating current of 35 μA (at 400 kHz)
    • Timekeeping down to 1.0 V
    • 1.3 V to 4.4 V I2C bus operating voltage
    • Software clock calibration to compensate deviation of crystal due to temperature
    • Software programmable output (OUT)
    • Operating temperature of –40 to 85 °C
    • Automatic leap year compensation
    • Lead-free 16-pin QFN package
    • Li-ion rechargeable operation
