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.
