Low power modes
RF transceiver operational modes
|Transmit (TX)||TR is transmitting an RF packet||Very short periods||As low as possible, but given mostly by RF output power||Important|
|Receive (RX)||TR is receiving or attempting to detect incoming RF packet||Majority of non-sleeping time||As low as possible||Crucial|
|Run||TR is operating (either with or without RF circuitry sleeping) but no RX or TX is in progress||Negligible||Not critical||Negligible|
|Sleep||No operation (including incoming RF signal detection) is possible until TR wakes up.||Majority of time||1 µA order of magnitude for battery life of years||Necessary|
|Deep sleep||No operation (including incoming RF signal detection) is possible. Complete initialization of RF circuitry must be performed after TR awakening.||Very long periods (if applicable)||Extremely low power in very long periods of inactivity. In special applications only.||Either not critical or crucial|
IQRF extra low power consumption
IQRF is outstandingly suitable for battery operated devices.
- Sleep - tens or hundreds of nanoAmpers
- RX - as low as outstanding 15 µA in consumption optimized (XLP) mode. To optimize the consumption in this most crucial mode (see the table above) for various needs, three RX/TX modes are available: STD (Standard), LP (Low Power) and XLP (Extra Low Power).
- Even lower is receiving in LP combined with sub-µA precisely timed sleeping.
That is why battery-operated network Coordinator and routers are enabled.
