AM1815AQ, Artasie RTC, SPI and Power management

The Ambiq Artasie Real-Time Clock family AM18X5 with Power Management provides a groundbreaking combination of ultra-low power coupled with a highly sophisticated feature set. With power requirements significantly lower than any other industry RTC (as low as 14 nA), these are the first semiconductors based on Ambiq's innovative SPOTTM (Subthreshold Power Optimized Technology) CMOS platform.

The AM18x5 includes on-chip oscillators to provide minimum power consumption, full RTC functions including battery backup and programmable counters and alarms for timer and watchdog functions, and an I2C (AM1805) or SPI (AM1815)  PC serial interface for communication with a host controller. An integrated power switch and a sophisticated system sleep manager with counter, timer, alarm, and interrupt capabilities allows the AM1805 to be used as a supervisory component in a host microcontroller based system.
