Figure 7 demonstrates the timing and current consumption in each mode associated with commanding the chip
from SHUTDOWN to TX state. Figure 8 demonstrates the timing and current consumption for each mode
associated with commanding the chip from STANDBY to TX state. The most advantageous state to use will
depend on the duty cycle of the application or how often the part is in either RX or TX state. In most applications
the utilization of the STANDBY state will be most advantageous for battery life but for very low duty cycle
applications SHUTDOWN will have an advantage. For the fastest timing the next state can be selected in the “Start
RX” or “Start TX” API commands to minimize SPI transactions and internal MCU processing.
TX = 19 mA
Tune = 100 µs @ 7.3 mA
Reg Inrush = 5 µs @ 2 mA
Ready = 300 µs @ 1.8 mA
POR = 20 ms @ 1.25 mA
Standby = 10 µs @ 50 nA
Shutdown = 30 nA
Shutdown = 30 nA
