Description
The Abracon Corporation AB18XX Real Time Clock with
Power
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 15nA), these are
the first semiconductor products based on Abracon Corporation’s
innovative SPOT (Sub-threshold Power Optimized Technology
by Ambiq Micro) CMOS platform. The AB18XX 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 either
an I
controller. An integrated power switch and a sophisticated
system sleep manager with counter, timer, alarm, and interrupt
capabilities allows the AB18XX to be used as a supervisory
component in a host microcontroller-based system.
