AB1815-T3 Description
The ABRACON AB18X5 Real-Time Clock with Power Management 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 the innovative SPOTTM(Subthreshold Power Optimized Technology) CMOS
platform. The AB18X5 includes on-chip oscillators to provide minimum power consumption, full RTC functions including battery backup, programmable
counters and alarms for timer and watchdog functions, and an I2C or SPI 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 AB18X5 to be used as a supervisory
component in a host microcontroller-based system.
