XStream™ OEM RF Module – Product Manual v5.x00 [2006.02.24]
Pin Sleep (SM = 1)
Pin Sleep requires the least amount of power. In order to achieve this state, SLEEP pin must be
asserted (high). The module remains in Pin Sleep until the SLEEP pin is de-asserted.
After enabling Pin Sleep Mode, the SLEEP pin controls whether the module is active or in Sleep
Mode. When SLEEP is de-asserted (low), the module is fully operational. When SLEEP is asserted
(high), the module transitions to Sleep Mode and remains in its lowest power-consuming state
until the SLEEP pin is de-asserted. SLEEP is only active if the module is setup to operate in this
mode; otherwise the pin is ignored.
Once in Pin Sleep Mode,
is de-asserted (high), indicating that data should not be sent to the
module. The PWR pin is also de-asserted (low) when the module is in Pin Sleep Mode.
Note: The module will complete a transmission or reception before activating Pin Sleep.
Serial Port Sleep (SM = 2)
Serial Port Sleep is a Sleep Mode in which the XStream Module runs in a low power state until
serial data is detected on the DI pin.
When Serial Port Sleep is enabled, the module goes into Sleep Mode after a user-defined period
of inactivity (no transmitting or receiving of data). This period of time is determined by ST (Time
before Sleep) Command. Once a character is received through the DI pin, the module returns to
Idle Mode and is fully operational.
Cyclic Sleep (SM = 3-8)
Cyclic Sleep is the Sleep Mode in which the XStream Module enters into a low-power state and
awakens periodically to determine if any transmissions are being sent.
When Cyclic Sleep settings are enabled, the XStream Module goes into Sleep Mode after a user-
defined period of inactivity (no transmission or reception on the RF channel). The user-defined
period is determined by ST (Time before Sleep) Command.
While the module is in Cyclic Sleep Mode,
is de-asserted (high) to indicate that data should
not be sent to the module during this time. When the module awakens to listen for data,
is
asserted and any data received on the DI Pin is transmitted. The PWR pin is also de-asserted
(low) when the module is in Cyclic Sleep Mode.
The module remains in Sleep Mode for a user-defined period of time ranging from 0.5 seconds to
16 seconds (SM Parameters 3 through 8). After this interval of time, the module returns to Idle
Mode and listens for a valid data packet for 100 ms. If the module does not detect valid data (on
any frequency), the module returns to Sleep Mode. If valid data is detected, the module
transitions into Receive Mode and receives incoming RF packets. The module then returns to
Sleep Mode after a Period of inactivity that is determined by ST “Time before Sleep” Command.
The module can also be configured to wake from cyclic sleep when SLEEP (pin 2) is de-asserted
(low). To configure a module to operate in this manner, PW (Pin Wake-up) Command must be
issued. Once SLEEP is de-asserted, the module is forced into Idle Mode and can begin
transmitting or receiving data. It remains active until no data is detected for the period of time
specified by the ST Command, at which point it resumes its low-power cyclic state.
Note: The cyclic interval time defined by SM (Sleep Mode) Command must be shorter than the
interval time defined by LH (Wake-up Initializer Timer).
For example: If SM=4 (Cyclic 1.0 second sleep), the LH Parameter should equal 0x0B (“1.1”
seconds). With these parameters set, there is no risk of the receiving module being asleep for the
duration of wake-up initializer transmission. “Cyclic Scanning” explains in further detail the
relationship between “Cyclic Sleep” and “Wake-up Initializer Timer”
