Typically, designers want to run MCU functions as fast as possible and return to “sleep mode” to conserve energy. This is a benefit that the M0+ core brings; it runs fast. Add to that the enhancements that the Kinetis L brings to the table, like bit manipulation, bridge controls, and other low-power options to further reduce the time a design has to stay “powered up”. The Kinetis L family is designed to stay in the low power mode with a host of peripherals designed to reduce the necessity to wake up the core, resulting in improved energy efficiency and increased battery life.
