Serial 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

QFN16 3 mm x 3 mm

■ Serial interface supports I C bus (400 kHz)

■ 525 nA timekeeping current at 3 V

■ Low operating current of 35 µA (at 400 kHz)

■ Timekeeping down to 1.0 V

■ 1.3 V to 4.4 V I C bus operating voltage

– Allows use in lithium ion rechargeable

applications

■ 32 KHz square wave on power-up to drive a

microcontroller in low-power mode

■ Programmable (1 Hz to 32 KHz) square wave

■ Programmable alarm with interrupt function

■ 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
