2.1. Operating Modes
The Si4330 provides several operating modes which can be used to optimize the power consumption for a given
application. Depending upon the system communication protocol, an optimal trade-off between the radio wake time
and power consumption can be achieved.
Table 8 summarizes the operating modes of the Si4330. In general, any given operating mode may be classified as
an active mode or a power saving mode. The table indicates which block(s) 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 operating mode. An “X” in any cell means that, in the given mode of operation,
that block can be independently programmed to be either ON or OFF, without noticeably impacting the current
consumption. The SPI circuit block includes the SPI interface hardware and the device register space. The 32 kHz
OSC 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, general purpose ADC, and low-battery detector.
