3.4.3. Sleep Mode
Pin/Host-controlled Sleep Modes
Sleep Modes enable the RF modem to enter states of low-power consumption when not in use. In
order to enter Sleep Mode, one of the following conditions must be met (in addition to the modem
having a non-zero SM parameter value):
Table 3‐04. Sleep Mode Configurations
The SM command is central to setting Sleep Mode configurations. By default, Sleep Modes are
disabled (SM = 0) and the modem remains in Idle/Receive Mode. When in this state, the modem is
constantly ready to respond to serial or RF activity.
Higher Voltages. Sleep Mode current consumption is highly sensitive to voltage. Voltages above
3.0V will cause much higher current consumption.
Table 3‐05. Sample Sleep Mode Currents
The transient current when waking from pin sleep (SM = 1 or 2) does not exceed the idle current
of the modem. The current ramps up exponentially to its idle current.
Pin Hibernate (SM = 1)
Pin Hibernate Mode minimizes quiescent power (power consumed when in a state of rest or
inactivity). This mode is voltage level-activated; when DTR is de-asserted, the modem will finish
any transmit, receive or association activities, enter Idle Mode and then enter a state of sleep. The
modem will not respond to either serial or RF activity while in pin sleep.
To wake a sleeping modem operating in Pin Hibernate Mode, assert DTR (Data Terminal Ready).
The modem will wake when DTR is asserted and is ready to transmit or receive when the CTS line
is low. When waking the modem, the pin must be asserted at least two 'byte times' after CTS goes
low. This assures that there is time for the data to enter the DI buffer.
