Creating a simple, sleek design is harder than it looks!
Situation: A top fitness watch manufacturer wanted to bring a smart watch to market with complex fitness algorithms, including heart rate monitoring, packaged inside a sleek design. To provide the ultimate user experience with a long lasting battery, the designers needed a high-performance processor with an energy-friendly power profile; and Silicon Labs’ MCU family offered the most advanced and flexible energy-friendly MCUs on the market.
Solution: Not only are they energy efficient across active and sleep modes, but they also have ultra-fast wake-up times. These MCUs feature best-in-class architectural innovations to achieve power reduction within every block of the MCU, resulting in longer battery life. The EFM32 Wonder Gecko has an ARM® Cortex®-M4F core, with a digital signal processor (DSP) hardware floating-point unit (FPU) for faster computation performance.
The energy-efficient EFM32 MCU in a small package, allowed the product managers to reached their goal of an ultra-thin, lightweight product. Not only was the product design sleeker, but it also delivered a 2x longer battery life than the other MCUs they considered.
Benefit: The EFM32 family also offers MCU fundamentals that make energy management simple.
Energy Mode: Operating condition that balances effective circuit operation with the lowest possible energy usage. EFM32 offers five energy modes: Run, Sleep, Deep Sleep, Stop and Shutoff. Learn more
Simplicity Studio™: A suite of software and documentation tools for automatic code creation, debugging and power profiling, enabling designers to easily capitalize on IoT and embedded design challenges. Learn more
