Wearable devices, from smart watches to portable health and fitness trackers, are changing many aspects of our daily lives. A successful wearable device must deliver the right combination of price, performance, functionality and battery life, as well as a unique look, feel and behavior to differentiate itself from its competitors.
To reduce the microcontroller’s impact on the wearable platform’s energy budget, it is important to minimize the frequency and duration of any task that requires it to awaken from a low-power sleep mode. One of the primary ways to optimize a low-power embedded design is to find an MCU offering the lowest sleep mode that still provides adequate response to real-time events. Most MCUs using the ARM Cortex®-M processing core support multiple sleep modes.
Powering some of today’s hottest wearable products such as the Misfit Shine and the Magellan Echo smart sports watch, our EFM32 Gecko microcontroller family uses standard 32-bit ARM Cortex®-M cores combined with an energy-optimized set of peripherals and clocking architecture.
The EFM32 architecture has been designed from the ground up specifically for energy-sensitive applications. The architecture features a range of power modes that enable developers to achieve the optimal energy efficiency required by wearables.
