Artasie Real-Time Clock - AM0805 01

Artasie RTC AM0805 AM0805AQ (Back)

The Ambiq® Artasie Real-Time Clock AM0805 provides a ground-breaking 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 SPOT® (Subthreshold Power Optimized Technology) CMOS platform.
