M41T66
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)
■ 525 nA timekeeping current at 3 V
■ Low operating current of 35 A (at 400 kHz)
