Running mbed on EFM32® Devices Will
Accelerate Deployment of Energy-Friendly Internet of Things Applications
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Labs (NASDAQ: SLAB), a leading provider of microcontroller, sensing
and wireless connectivity solutions for the Internet
of Things (IoT), today announced a collaboration with ARM to define
and deliver the first power management application programming
interfaces (API) for ARM® mbed™ platforms. Adding
power management APIs to mbed will bring energy efficiency to
standards-based solutions optimized for ultra-low-power,
battery-operated connected devices. The new APIs will enable the mbed
community of more than 100,000 registered developers to optimize their
mbed-enabled ARM Cortex®-M architecture-based designs for the
utmost energy efficiency and longer battery life.
In addition to enabling developers to manage processor and peripheral
states, the mbed power management APIs are designed with real-world,
low-energy application scenarios in mind. A new feature exposed by the
APIs on Silicon Labs' EFM32® Gecko microcontrollers (MCUs)
automatically determines and enables the optimal sleep mode based on the
MCU peripherals in use, which can dramatically reduce system-level
energy consumption. Low-energy optimization is achieved by enabling I/O
operations to be executed in the background and by allowing those
operations to continue even while the MCU core is in sleep mode or
during other processing tasks.
The automatic selection of the optimal sleep mode, combined with
low-energy, autonomous MCU peripherals, enables developers to
significantly reduce the energy consumption of their IoT applications
with minimal effort. For example, energy profiles of an application
updating a clock display every second on a memory LCD - a common use
case for IoT devices - have shown a current consumption reduction from
1.03 mA to 0.100 mA.
"The new power management APIs for ARM mbed make it possible for
developers to create applications that take advantage of the low-power
features of ARM Cortex-M based microcontrollers," said Zach Shelby, vice
president, IoT business marketing, ARM. "This is an important step
toward enabling full energy-awareness in IoT devices, and it is one of
the key building blocks for mbed OS that is due for public release later
this year."
"As pioneers in low-energy processing solutions for the IoT, Silicon
Labs and ARM have made enormous progress in defining and delivering the
new power management APIs for mbed," said Daniel Cooley, vice president
and general manager of Silicon Labs' MCU and wireless products. "We're
excited to help deliver the industry's first low-power mbed platform,
which will play a key role in accelerating the deployment of countless
battery-powered IoT applications."
Availability
Silicon Labs plans to provide mbed-enabled EFM32
Gecko starter kits in April 2015. Silicon Labs' initial platforms
supporting mbed will include the Wonder Gecko, Leopard Gecko, Giant
Gecko and Zero Gecko starter kits. Developers with existing EFM32 kits
will be able to mbed-enable their hardware through a simple software
update. For more information about Silicon Labs' mbed platforms, please
