Features and Applications

The M41T00M6F is a part of M41T series I2C RTC. It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOIC-8 Packaging.

The M41T00 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.


  • 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 85˚C
