Real-time clock module RV-1805-C3

RV-1805-C3 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. User programmable offset value. Automatic Backup Switchover and Trickle Charger function. Provides year, month, date, weekday, hours, minutes, seconds, 100th. Timer, Alarm, External event and Watchdog functions. 256 bytes user RAM. The RV-1805-C3 RTC module has been specially designed for ultimate low power consumption: IoT Wearables, Portables Health Care Metering Industrial Key element for power management
