Features and Applications

The M41T56M6F 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.

Features:

  • 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 450 nA (typ at 3 V)
  • 5 V ±10% supply voltage
  • Timekeeping down to 2.5 V
  • Automatic power-fail detect and switch 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 °C to 85 °C
  • Available in an 8-lead, 150-mil, plastic SOIC (SO8)
  • RoHS compliant
  • Lead-free second level interconnect
