The Ambiq Micro AM18xx Low Power Real-Time Clock (RTC) family provides a groundbreaking combination of ultra-low power coupled with a highly sophisticated feature set optimized for system-level power management. With power requirements significantly lower than any other industry RTC (as low as 14nA in RC mode, 22nA in auto calibration mode, 55nA in XT mode), these are the first semiconductor products based on Ambiq Micro’s innovative SPOT™ (Subthreshold Power Optimized Technology) CMOS Platform.

Advanced power management features includes an integrated power switch and a sophisticated system sleep manager with counter, timer, alarm, and interrupt capabilities that allows the AM18xx to be used as a complete system-level power manager.
