Features and Applications

The M41T11M6F is a low power serial real-time clock (RTC) with a built-in 32.768 KHz oscillator and 56 bytes of NVRAM, available in SOIC-8 package.

The clock has a built-in power sense circuit which detects power failures and automatically switches to the battery supply during power failures. The energy needed to sustain the RAM and clock operations can be supplied from a small lithium coin cell.


  • Counters for seconds, minutes, hours, day, date, month, years and century
  • 32 kHz crystal oscillator integrating load capacitance (12.5 pF) 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 5.5 V clock operating voltage
  • Automatic switchover and deselect circuitry
  • 56 bytes of general purpose RAM
  • Software clock calibration to compensate crystal deviation due to temperature
  • Automatic leap year compensation
  • Operating temperature of -40 to 85°C
  • Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately; 3.3V to 5.0V supply voltage only)
  • RoHS compliant
  • Lead-free second level interconnect
