Description
This RTC IC has been specially designed for ultimate low current
consumption of typically 60 nA @ V_DD 3.0V for 32.768 kHz XTAL mode.
Additionally, there is an RC-Mode consuming only 17nA and an
autocalibrated RC-mode consuming 22nA which permits to operate this
RTC module several hours at Backup Supply Voltage using low-cost MLCC.
The very small SMT ceramic-package combines the 32.768 kHz crystal unit
with the CMOS-based oscillator and real-time-clock IC. The calender
function track year, month, date, and day-of-the-week. Thefactory
calibrated clock achieves a time accuracy of typ. ±2.0 ppm @ 25°C and
tracks hundredths of second, second, minute and hour in AM/PM or
24-hour format. Additional features include Alarm, Timer and Interrupt
functions, Watchdog Timer, Power Management with Power-Switch,
Trickle Charger and Automatic Switchover to backup supply voltage.
