Serial SPI bus real-time clock (RTC) with battery switchover

Features  Ultra-low battery supply current of 365 nA  Factory calibrated accuracy ±5 ppm typical after 2 reflows (SOX18) (much better accuracies are achievable using built-in programmable analog and digital calibration circuits)  2.0 V to 5.5 V clock operating voltage  Counters for ten
