Key features
  • Serial real-time clock (RTC) with alarm functions
    • 400 kHz I²C serial interface
    • Memory mapped registers for seconds, minutes, hours, day, date, month, year, and century
    • Tenths/hundredths of seconds register
  • 350 nA timekeeping current at 3 V
  • Timekeeping down to 1.0 V
  • 1.3 V to 4.4 V I²C bus operating voltage
    • 4.4 V max VCCsuitable for lithium-ion battery operation
  • Low operating current of 35 μA (at 400 kHz I²C speed)
  • 32 kHz square wave output is on at power-up. Suitable for driving a microcontroller in low-power mode. Can be disabled. (M41T62/64)
  • Programmable 1 Hz to 32 kHz square wave output (M41T62/64)
  • Programmable alarm with interrupt function (M41T62/65)
  • 32 kHz crystal oscillator integrates crystal load capacitors, works with high series resistance crystals
  • Oscillator stop detection monitors clock operation
  • Accurate programmable watchdog
    • 62.5 ms to 31 minutes timeout
  • Software clock calibration. Can adjust timekeeping to within ±2 parts per million (±5 seconds per month)
  • Automatic leap year compensation
  • –40 to +85 °C operation
  • Two package options:
    • Very small 3 x 3 mm, lead-free and halogen-free (ECOPACK2) 16-lead QFN
    • Ultra-small 1.5 x 3.2 mm, lead-free and halogen-free (ECOPACK2) 8-pin ceramic leadless chip carrier with embedded 32 kHz crystal - no external oscillator components required (M41T62)
