RV-1805-C3 (Not recommended for new Design) Real Time Clock with Power Management provides a groundbreaking combination of ultra-low power coupled with a highly sophisticated feature set. The power requirement is significantly lower than any other industry RTC (as low as 17 nA). The RV-1805-C3 includes an on-chip oscillator to provide a minimum power consumption, full RTC functions including battery backup and programmable counters and alarms for timer and watchdog functions, and either an I²C 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 RV-1805-C3 to be used as a supervisory component in a host microcontroller based system.

  • Extreme low power consumption: XTAL mode, 60 nA @ 3 V.
