The tiny package of just 3.5 x 1.5 x 0.8 mm combines the quartz crystal with the RTC circuit, offering also an integrated battery-back-up switch. The extreme low power consumption allows using MLCC capacitors to cover the back-up time. Together with an event detection input it features all the prerequisites for Wearables, Medical Healthcare and power sensitive IoT applications.
- Industries lowest current consumption of only 40 nA at 3 V supply
- Factory calibrated time reference ±1.0 ppm at 25°C
- Integrated 32.768 kHz Quartz Crystal
- Battery back-up switch with trickle charge ideal also for MLCC and Supercap
- Wide voltage range 1.2 to 5.5V
- Ultra-miniature ceramic SMD package: 3.2 x 1.5 x 0.8 mm
- Provides year, month, date, weekday, hours, minutes and seconds
- 32 bit Unix time counter e.g. for security code calculations
- I²C interface 400 kHz
