AUSTIN, TX -- Ambiq Micro, the leader in ultra-low power solutions, reveals Misfit, Inc. has selected the Apollo microcontroller (MCU) as the 'brain' in the Misfit Shine 2 Fitness and Sleep Monitor. Announced just last week, the next-generation Misfit Shine 2 provides new features, functions and capabilities without sacrificing its market leading 6-months of battery life. Shine 2 tracks activity and sleep more accurately with a 3-axis accelerometer and newly added 3-axis magnetometer, displays progress and tells time in a halo of rainbow-colored lights, and gets users motivated with Misfit Move, a feature that encourages users to be active with a vibrational nudge. Text and call notifications and a silent vibration alarm are also new with Shine 2.
The Misfit Shine 2 also incorporates dramatically improved touch responsiveness with capacitive sensing technology, faster syncing, and extended Bluetooth range. Its 12 lights display over 16 million colors and are bright enough to be seen in direct sunlight.
"Shine 2 would not be what it is without this processor," said Steve Diamond, VP of Hardware Engineering at Misfit. "It allowed us to focus less on power optimization and more building a next-generation product with the same great battery life."
The Apollo MCU will operate as the central processor and controller in the new Misfit Shine 2, handling overall device operations including processing inputs from the device's motion and environmental sensors and also controlling wireless communication with the outside world.
Ambiq Micro's interim CEO, Mike Noonen, said: "The selection by a major wearable electronics leader such as Misfit to use the Apollo microcontroller is a significant endorsement of our unique production ready technology and our ability to work closely with world-class consumer companies. The Ambiq Micro team is thrilled that our order of magnitude low power advantage is used so effectively in the Shine 2."
Based on the 32-bit ARM® Cortex-M4 with FPU, in real-world applications the Apollo MCU delivers typically 5 to 10 times lower energy consumption than other competitive MCUs. This high level of performance per watt can mean significantly extended battery life, the use of smaller or fewer batteries, and/or the ability to add new features not previously possible. These benefits are critically important for wearable electronics and other battery-powered applications.
The dramatic reduction in energy consumption is achieved using Ambiq's patented Subthreshold Power Optimized Technology (SPOTTM ) platform. In addition, the Apollo MCU offers best-in-class power consumption numbers in both active-mode and sleep-mode - a capability that is unique in the industry. The Apollo MCU consumes an industry-leading 34µA/MHz when executing instructions from flash memory and features sleep-mode currents as low as 140nA.
