M41T00M6F Datasheet

Real Time Clock


The M41T00M6F is a low power serial real time clock with a built-in 32.768 kHz oscillator (external crystal controlled). Eight bytes of the RAM areused for the clock/calendar function and are configured in binary coded decimal (BCD) format. Addresses and data are transferred serially via a two-line bi-directional bus. The built-in address register is incremented automatically after each WRITE or READ data byte. M41T00M6F Features • For new designs use M41T00S• Counters for seconds, minutes, hours,day, month, years, and century• 32 kHz crystal oscillator integrating load capacitance (12.5pF) providing exceptional oscillator stability and high crystal series resistance operation• Serial interface supports I2C bus (100 kHz protocol)• Ultra low battery supply current of 0.8 μA (typ at 3V)• 2.0 to 5.5V clock operating voltage• Automatic switchover and deselect circuitry (for 3V application select M41T00S datasheet)• Software clock calibration to compensate crystal deviation due to temperature• Automatic leap year compensation• Operating temperature of -40 to 85C
