Low Power MCU Selection Criteria


Power consumption in active and standby modes
Multiple operating and standby modes



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

4
Set to different operating and standby modes for optimization of current
consumption based on required operations.
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
