3.4.2. Deep Sleep Mode

Based on system performance, the module consumes an ultra-low current (typically 4.2μA power
consumption) in Deep Sleep mode. Deep Sleep mode is designed to reduce power consumption of the
module and improve battery life. The following figure shows the power consumption of the module in
different modes.
BC950N-N1_Hardware_Design
Connected state: in Connected mode, module can send and receive data,
and modem can be switched to DRX/eDRX mode or PSM mode.
Idle state: in DRX/eDRX mode, modem is in idle state and downlink data
can only be received in paging window. In this mode, modem can be
switched to Connected or PSM mode.
Power saving state: modem is in disconnected state and cannot receive
downlink data. In this mode, modem can be switched to Connected mode.
Wake-up state: When AP is in Normal mode or modem is in Connected
mode, module is in Active mode. In this mode, all services can be
processed normally and power consumption reaches the highest level.
Light sleep state: When AP is in Idle mode and modem is in DRX/eDRX
mode, the module will enter into Light Sleep mode. At this time, AP task
is suspended, modem does not receive downlink data or only receives
downlink data in paging window, and power consumption is greatly
reduced to μA level.
Deep sleep state: When AP is in Idle mode and modem enters into PSM
mode, module will enter into Deep Sleep mode. At this point, CPU will be
powered down and only internal RTC still works; while power
consumption of the module reaches the lowest level, which is about
4.2μA.
