Autonomous peripherals make smart devices more energy-efficient and batteries smaller by keeping microcontrollers in sleep mode. Take a look at our customer success story to find out more.
Situation: A major consumer electronics brand wanted a smarter design for their next generation battery-powered consumer device. The challenge was to stay true to their feature rich product image, but get rid of the initial design with a large battery which made it look and feel bulky. A solution was needed to enable a stylish design with advanced features that did not sacrifice performance, battery life or functionality.
Solution: The energy-friendly EFM32™ microcontroller (MCU) family from Silicon Labs solved the customer’s needs with its EFM32™ autonomous peripherals. These peripherals manage sensor inputs, thresholds and alarm triggers without the intervention of the main core. Circuits outside of the microcontroller which can perform complex operations on their own while the main processor core remains in sleep mode. The peripherals communicate over Silicon Labs’ unique peripheral reflex system so that the MCU can stay in sleep mode longer for even greater energy savings.
