Serial RTC with battery switchover

Description The M41T8x are low power Serial I2C Real Time Clocks with a built-in 32.768kHz oscillator (external crystal-controlled for the QFN16 and SO8 packages, embedded crystal for the SOX18 package). Eight bytes of the Register Map (see Table 2 on page 23) are used for the clock/calendar func

Serial I2C bus real-time clock (RTC) with battery switchover

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