Figure 7: VCC current consumption profile versus time of the SARA-G350 modules or the SARA-G300 / SARA-G310 modules (with the
EXT32K input fed by a proper external 32 kHz signal), when registered with the network, with power saving enabled: the very low power
idle-mode is reached and periodical wake up to active-mode are performed to monitor the paging channel
roughly describes the current consumption profile of SARA-G300 / SARA-G310 modules
when the
EXT32K
input pin is fed by the
32K_OUT
output pin provided by these modules, when power
saving is enabled. The module is registered with the network, automatically enters the low power idle-
mode and periodically wakes up to active-mode to monitor the paging channel for paging block reception.
