MC1322x Technical Data, Rev. 1.3
Freescale Semiconductor

3.3
Low Power Operation and Power Management
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
Operating Current
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 Section 7.4, “Supply
Current Characteristics” for more details and specifications.
3.3.2
Power Management
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.
3.3.2.1
CRM Features
The CRM features include:
Control of system reset
Control clock gating for power savings
Sleep mode (Hibernate and Doze) management
— Degree of chip power down
— Retention of programmed parameters
— Programmable retention of RAM contents
— Clock management
Wake-up management
— Graceful power-up
— Clock management
— Wake-up via programmable timer or external interrupts.
Wake-up timer
— Hibernate mode - based on onboard 2 kHz oscillator or optional 32.768 kHz crystal oscillator
— Doze mode - based on main reference oscillator, typically 24 MHz
Controls reference clocks based on default 24 MHz crystal oscillator or optional 13-26 MHz
oscillator with PLL (external filter) for 24 MHz frequency synthesis.
MCU watchdog timer (COP)
Software initiated reset
Management control of onboard linear regulators and optional buck regulator
