NEW: real-time clock (RTCs) by Micro Crystal

This RTC IC has been specially designed for ultimate low current

consumption of typically 60 nA @ VDD 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. The

factory 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.

For pick-and-place equipment, the parts are available in 12 mm tape:

7” (178 mm) reel with 1'000 or 3'000 parts

13” (330 mm) reel with 10'000 parts
