3.3
The MC1322x is inherently a very low power device, but it also has extensive power management and an
onboard buck regulator option to maximize battery life.
3.3.1
The MC1322x operating currents are a function of operating mode. There are two basic low power modes
of Hibernate and Doze, and both have options of how much RAM contents are retained. The difference
between Hibernate and Doze is that Doze mode keeps the primary reference oscillator running.
Highest operating current is when the radio is active for transmit or receive. Refer to
Current Characteristics”
3.3.2
The MC1322x power management is controlled through the Clock and Reset Module (CRM). The CRM
is a dedicated module to handle MCU clock, reset, and power management functions which includes
control of the power regulators. All these functions have impact on attaining lowest power.
