VRTC is provided in order to allow for optional integration of an external battery source (2.0V to 3.25V) for
feeding the module's real-time clock (RTC). VRTC is only required to keep the date/time when the main
power supply is not connected. All other data is saved in the persistent FLASH memory. The expected
consumption is around 0.0045 mA. Based on the desired holdup time, the system integrator should select
the appropriate battery capacity. We recommend using Seiko Instruments MS621FE-FL11E coin cell battery,
which is rated at 3V output and 5.5 mAh capacity.
J1 provides standard 4-wire network connectivity. You only need 4 wires for 10/100 Base-T
network connection; please connect the appropriate network connection pins to your RJ45
connector or wiring. Network status LED pins are also accessible if needed.
