    RTC battery voltage range and connections

    Blackhole

      Hi,

       

      Please reply to following queries regarding RTC:

       

      1. What is the voltage range of battery that can be connected to V_VBAT_BKUP pin (pin23 on the edison, pin 5 of J18 on the mini breakout)?

      2. Can the -ve terminal of battery be connected to any common ground?

      3. What is the power rating of the RTC circuit?

      4. Can we connect rechargeable battery to RTC? What are the configuration settings to enable the recharge when power is on?

      5. On Mini breakout board, can I connect the same 3.7V battery to J2 & V_VBAT_BKUP?

       

      Regards
