Description
The ABRACON 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 14 nA), these are
the first semiconductors based on innovative
SPOTTM (Subthreshold Power Optimized
Technology) 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 I2C or
SPI serial interface for communication with a host
controller.
Disclaimer: AB08XX series of devices are
based on innovative SPOT technology,
proprietary to Ambiq Micro.
