Serial access real-time clock with alarms
Features
■ Counters for tenths/hundredths of seconds,
seconds, minutes, hours, day, date, month,
year, and century
■ 32 KHz crystal oscillator integrating load
capacitance and high crystal series resistance
operation
■ Oscillator stop detection monitors clock
operation
■ Serial interface supports I2C bus (400 kHz)
■ 350 nA timekeeping current at 3 V
■ Low operating current of 35 A (at 400 kHz)
■ Timekeeping down to 1.0V
■ 1.3 V to 4.4 V I2C bus operating voltage
■ 32 KHz square wave on power-up to drive a
microcontroller in low power mode
(M41T62/63/64)
■ Programmable (1Hz to 32 KHz) square wave
(M41T63/64)
■ Programmable alarm with interrupt function
(M41T62/65)
■ Accurate programmable watchdog
(from 62.5 ms to 31 min)
■ Software clock calibration to compensate
deviation of crystal due to temperature
■ Automatic leap year compensation
■ Operating temperature of –40 to 85 °C
■ Lead-free 16-pin QFN package
■ Lithium-ion rechargeable operation
