Abracon AB0815-T3, Real Time Clock, 256B RAM Serial-SPI, 16-Pin QFN

The Abracon Real-Time Clock family 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 innovative SPOTTM (Subthreshold Power Optimized Technology) CMOS platform. The AB0815-T3 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.

Ultra-low supply current
Counters for hundredths, seconds, minutes, hours, date, month, year, century, and weekday
Alarm capability on all counters
Integrated power optimized RC oscillator
External interrupt monitor
Programmable low battery detection threshold
