Low Power MCU Selection Criteria

� Power consumption in active and standby modes

� Multiple operating and standby modes

� Set to different operating and standby modes for optimization of current consumption based on required operations.

� High peripheral integration

� Peripherals built into chip to simplify designs and reduce leakage current draw from external devices.

� Current consumption can be optimized by enabling only required peripherals and disabling unused peripherals.

� Flexible clocking scheme and various selectable clock sources

� Using most efficient clock source for CPU and peripherals can optimize required performance, required operation and current consumption.

� Flexible wakeup schemes from standby to active modes

� Minimal wakeup time from standby to active can optimize current consumption based on required operation and performance.

� Methods to Wakeup from Standby Modes (HALT, STOP)

� Interrupt

� Reset

– In reset, both CPU and subsystem clocks stop

– Reset released, CPU run with internal high-speed oscillator

– After reset, wakeup time dependent on external crystal, external clock or internal oscillator stabilization time.

� HALT mode� CPU clock (external system clock or internal oscillator) continue to run

� Subsystem clock continue to run

� STOP mode� CPU clock (external system clock or internal oscillator) stop

� Subsystem clock continue to run
