Description
The Abracon Corporation AB08XX Real Time Clock family
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 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 AB08XX 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
SPI serial interface for communication with a host controller.
