Si4313-B1
2.2. Operating Modes
The Si4313 provides several operating modes, which can be used to optimize the power consumption of the
receive application. Depending upon the system communication protocol, an optimal trade-off between radio wake
time and power consumption can be achieved.
In general, any given operating mode may be classified as an Active mode or a Power Saving mode. Table 8
indicates which blocks are enabled (active) in each corresponding mode. With the exception of the Shutdown
mode, all can be dynamically selected by sending the appropriate commands over the SPI. An "X" in any table cell
means that the block can be independently programmed to be either ON or OFF (in that given operating mode)
without noticeably impacting current consumption. The SPI block includes the SPI interface hardware and the
register space. The 32 kHz OSC circuit block includes the 32.768 kHz RC oscillator or 32.768 kHz crystal oscillator
and wake-up timer. AUX (Auxiliary Blocks) includes the temperature sensor and low-battery detector.
