The table below shows detailed information about the typical power consumption for the RTCU
NX-910 device when it is in power-saving modes.
The following power-saving modes are used:
➢
Mode 1:
LED blinks every ~10 s, resumes the application when it is awoken.
➢
Mode 2:
Does not blink, resumes the application when it is awoken.
➢
Mode 3:
Does not blink, resets the device when it is awoken.
See the RTCU IDE on-line manual for information about how to use the power saving modes.

Note:
If wake-up on both power fail and power apply are enabled, mode 2 and 3 are not supported.
Note:
Power consumption from a fully charged battery.
Note:
The RS232 ports have support for two different wake-up configurations. Mode 0 will wake
on valid data while mode 1 will wake on any change on the interface.
Note:
The power consumption for wake on S0 will be drawn as long as S0 is enabled.
AC power consumption: Device operating in power-saving modes
The power consumption from external AC is less than 1 W in all the power saving modes.
