AB18X5

The ABRACON AB18X5 Real-Time Clock family provides a
groundbreaking combination of ultra-low power coupled with a
highly sophisticated feature set.The AB08X5 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. An
integrated power switch and a sophisticated system sleep manager
with counter, timer, alarm, and interrupt capabilities allow the AB18X5
to be used as a supervisory component in a host microcontroller
based system.
