XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23]
Sleep Mode
Pin/Host-controlled Sleep Modes
Sleep Modes enable the RF module 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 module
having a non-zero SM parameter value):
Table 2‐04. Sleep Mode Configurations
The SM command is central to setting Sleep Mode configurations. By default, Sleep Modes are dis-
abled (SM = 0) and the module remains in Idle/Receive Mode. When in this state, the module is
constantly ready to respond to serial or RF activity.
The transient current when waking from pin sleep (SM = 1 or 2) does not exceed the idle current
of the module. 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 inac-
tivity). This mode is voltage level-activated; when Sleep_RQ (pin 9) is asserted, the module will
finish any transmit, receive or association activities, enter Idle Mode, and then enter a state of
sleep. The module will not respond to either serial or RF activity while in pin sleep.
To wake a sleeping module operating in Pin Hibernate Mode, de-assert Sleep_RQ (pin 9). The
module will wake when Sleep_RQ is de-asserted and is ready to transmit or receive when the CTS
line is low. When waking the module, the pin must be de-asserted at least two 'byte times' after
CTS goes low. This assures that there is time for the data to enter the DI buffer.
Pin Doze (SM = 2)
Pin Doze Mode functions as does Pin Hibernate Mode; however, Pin Doze features faster wake-up
time and higher power consumption.
To wake a sleeping module operating in Pin Doze Mode, de-assert Sleep_RQ (pin 9). The module
will wake when Sleep_RQ is de-asserted and is ready to transmit or receive when the CTS line is
