Silicon Labs, ARM Team Up on Power Management APIs for IoT Market

Silicon Labs said Thursday it's partnering with ARM to define and deliver power management APIs (application programming interfaces) for ARM mbed platforms. Power management will enable energy efficiency solutions for ultra-low-power, battery-operated connected devices, the companies said. A feature in the APIs automatically determines and enables the optimal sleep mode based on the microcontroller (MCU) peripherals in use, which can significantly reduce power consumption, they said. Low-energy optimization is achieved by enabling input/output operations to be executed in the background and by allowing the operations to continue even while the MCU core is in sleep mode or during other processing tasks, they said. The mbed platform will play a key role in accelerating the deployment of “countless battery-powered IoT applications," said Daniel Cooley, general manager-Silicon Labs MCU and wireless products.
